Purpose: Rule 9 covers a central principle of the game: “play the ball as it lies.”

  • If the player’s ball comes to rest and is then moved by natural forces such as wind or water, the player normally must play it from its new spot.
  • If a ball at rest is lifted or moved by anyone or any outside influence before the stroke is made, the ball must be replaced on its original spot.
  • Players should take care when near any ball at rest, and a player who causes his or her own ball or an opponent’s ball to move will normally get a penalty (except on the putting green).

Deciding Whether Ball Moved and What Caused It to Move
9.2a
Deciding Whether Ball Moved
9.2a/1
When a Ball Is Treated as Having Moved

As stated in the definitions, to "move", a ball at rest must leave its original spot and come to rest on any other spot and the movement must be enough that it can be seen by the naked eye. In order to treat the ball as moved, there must be knowledge or virtual certainty that the ball has moved.

An example of when it is known or virtually certain that a ball has moved is:

  • A player marks, lifts and replaces his or her ball on the putting green. As the player walks away, the ball rolls a short distance and comes to rest. The player does not see this, but another player observes the ball moving and informs the player. Since it is known that the ball moved, the player must replace the ball on its original spot under Rule 13.1d(2) (Ball Moved by Natural Forces).

An example of when it is not known or virtually certain that a ball has moved is:

  • Player A and Player B play their approach shots to the putting green, but because of the contours of the putting green they could not see where the two balls came to rest. Unknown to the players, Player B's ball struck Player A's ball at rest and it rolled some distance farther from the hole. As long as this information does not come to the attention of the players before Player A makes the next stroke, Player A does not get a penalty for playing from where his or her ball came to rest after being struck by Player B's ball.
9.2a/2
Player Responsible for Actions that Cause Ball to Move Even When Not Aware Ball Moved

In the second bullet point in 9.2a/1, the player did not make a stroke from a wrong place because it was not known or virtually certain that the ball had moved at the time the ball was played.

However, if it was the player's actions (or the actions of the player's caddie or partner) that caused the ball to move, the player is always responsible for the movement, even when the player is not aware that his or her actions caused the ball to move.

Examples of this include:

  • A player's ball lies in the general area and he or she removes a loose impediment near the ball that causes the ball to move. Because the player is not looking at the ball, he or she was not aware that the ball moved. The player gets one penalty stroke under Rule 15.1b (Ball Moved When Removing Loose Impediment) and he or she must replace the ball.
  • A player's caddie or his or her partner removed roping and staking, and this causes the player's ball to move while the player was watching another player make a stroke. There is no penalty for moving the ball under Rule 15.2a(1) (Removal of Movable Obstruction) but the player must replace the ball.

In both of these situations, even though the player was not aware that the ball moved, if the player makes a stroke without first replacing the ball, the player gets the general penalty for playing from a wrong place under Rule 14.7a (Place from Where Ball Must Be Played).

When Lifted or Moved Ball Must Be Replaced
9.4a/1
Procedure When Player’s Ball Is Dislodged From Tree

Rule 9.4 applies wherever a ball in play is on the course. This includes when a ball is in a tree. However, when the player does not intend to play the ball as it lies but is trying only to identify it, or intends to retrieve it to use another Rule, the Exceptions to Rule 9.4b apply and there is no penalty. For example:

  • In searching for his or her ball, a player sees a ball lying in a tree but cannot identify it. The player climbs the tree in an attempt to identify the ball and in doing so accidentally dislodges the ball from the tree. The ball is identified as the player's ball.
    In this case, since the ball was accidentally moved in taking reasonable actions to identify it, there is no penalty for moving the ball (Rule 7.4).
    The player must replace the ball or may directly use a relief Rule (such as Rule 19 - Unplayable Ball).
    In two situations, the player's only option is to take relief under a relief Rule:
    • The player is unable to replace the ball because he or she cannot reach the spot where the ball was moved from when the player was identifying it, or
    • The player can reach that spot but the ball will not come to rest on that spot and the player cannot reach the spot where it will come to rest under Rule 14.2e (Replaced Ball Does Not Stay on Spot).
  • A player's ball has not yet been found but is believed to be lodged in a tree in the general area. The player makes it clear that if the ball is found he or she will take unplayable ball relief under Rule 19. The player shakes the tree; the ball falls down and is identified by the player within three minutes of starting search.
    The player may now take relief under Rule 19 (Unplayable Ball) adding only the one penalty stroke prescribed by that Rule with no additional penalty for causing the ball to move. If not known, the player must estimate the spot where the ball lay in the tree when applying Rule 19.

However, if the player moves the ball when he or she is not intending to identify it or without intending to take relief under another Rule, the player does get a penalty for a breach of Rule 9.4. For example:

  • A player's ball is in a tree and he or she intends to play it. In preparing for the stroke, the player accidentally dislodges the ball.
    The player gets one penalty stroke under Rule 9.4 for causing the ball to move. The player must replace the ball or may take relief directly under a relief Rule. If the player takes relief under Rule 19, he or she gets a total of two penalty strokes, one under Rule 9.4 and one under Rule 19.
9.4b
Penalty for Lifting or Deliberately Touching Ball or Causing It to Move
9.4b/1
Ball Deliberately Touched but Not Moved Results in Penalty to Player

When the ball in play is deliberately touched by the player, even if it does not move, the player gets one penalty stroke under Rule 9.4b.

For example, a player gets one penalty stroke if he or she:

  • Without first marking the ball's spot, rotates the ball on the putting green to line up the trademark with the hole, even if the ball remains on the same spot. If the player had marked the ball before touching or rotating it, there would have been no penalty.
  • Without first marking the ball's spot, rotates the ball anywhere on the course to identify it and the ball is the player's ball.
  • Deliberately touches the ball with a club in preparing to make a stroke.
  • Holds the ball steady with his or her hand or positions a pine cone or stick against the ball to prevent the ball from moving while he or she removes some loose impediments or brushes something off the ball.
9.4b/2
Meaning of “Trying to Find”

In Rule 7.4 (Ball Accidentally Moved in Trying to Find or Identify It) and Exception 2 of Rule 9.4, there is no penalty if a ball is accidentally moved while "trying to find" it. "Trying to find" includes actions that can reasonably be considered part of searching for the ball, including the actions allowed by Rule 7.1 (How to Fairly Search for Ball). It does not include actions before a search begins such as walking to the area where the ball is expected to be.

For example, a player's ball is hit towards a wooded area. The player is not aware the ball has struck a tree and deflected back towards the teeing area. When the player is still some distance from the area where he or she believes the ball is likely to be and before starting to search, the player accidentally kicks his or her ball. Because this was not while trying to find the ball, the player gets one penalty stroke under Rule 9.4b for accidentally moving his or her ball and must replace the ball.

9.4b/3
Ball Moved When Search Temporarily Stopped

In 9.4b/2 a player gets a penalty if the ball is moved when he or she is not trying to find it.

However, If a player accidentally moves his or her ball when search is temporarily stopped due to circumstances outside the player’s control, the player gets no penalty for moving the ball.

For example:

  • The player stops searching for his or her ball to get out of the way of another group who is going to play through. While getting out of the way, the player accidentally moves his or her ball.
  • The Committee suspends play and the player begins to leave the area and accidentally steps on and moves his or her ball.
9.4b/4
Meaning of “While” in Rule 9 .4b Exception 4

Exception 4 uses "while" to govern the time period when the Exception will apply to a player who moves his or her ball in play as a result of "reasonable actions". For the meaning of "reasonable actions", see 9.4b/5.

The use of the word "while" indicates that every reasonable action in applying a Rule has a beginning and an end and, if the ball’s movement occurs during the time that such action is taking place, the Exception applies.

Examples of situations covered by Exception 4, therefore resulting in no penalty for causing the ball to move, include when:

  • The player finds a ball that he or she believes to be his or her ball in play. In the process of identification, the player approaches the ball to mark and lift it and accidentally slips and moves the ball.
    Even though the player was not marking or lifting the ball when it was moved, it was still moved while the player was identifying the ball.
  • The player has dropped a ball when taking relief and then reaches down to lift the tee that was marking the relief area. When standing up, he or she accidentally drops a club that he or she was holding and the club hits and moves the ball in play.
    Even though the player has already dropped the ball to take relief, the ball was moved while he or she was taking relief.
9.4b/5
Meaning of “Reasonable Actions” in Rule 9.4b Exception 4

In many situations, the Rules require a player to perform actions near or next to the ball (such as lifting, marking, measuring, etc.). If the ball is accidentally moved while taking these "reasonable actions", Exception 4 to Rule 9.4 applies.

However, there are other situations when the player is taking actions farther from the ball where, even though the ball might be moved as a result of those actions, Exception 4 also applies because those actions are "reasonable".

These include when:

  • The player approaches his or her ball for the purpose of taking relief and accidentally kicks a rock or accidentally drops his or her club that strikes and moves the ball.
  • The player removes stakes and rope (movable obstructions) used for gallery control purposes some distance ahead of the ball and in removing one of the stakes, he or she causes the others to become loose and fall to the ground, moving his or her ball in play.
  • The player restores the line of play by brushing sand away from the fringe with his or her hat under Rule 8.1d (Restoring Conditions Worsened After Ball Came to Rest), and the sand splashes onto the ball and causes it to move.

In other situations, Exception 4 to Rule 9.4 does not apply because the player's actions are not "reasonable".

These include when:

  • The player approaches his or her ball to take relief and kicks a rock in frustration that accidentally strikes and moves the ball.
  • The player throws a club down into the relief area in preparing to measure, and the club accidentally strikes and moves the ball.
  • The player lifts a bunker rake or his or her club and throws it out of a bunker. The rake or club falls back into the bunker, striking and moving the ball.
9.4b/6
Player Lifts Ball Under Rule 16 .1b That Allows Free Relief but Then Decides Not to Take Free Relief

In the general area, if a player lifts his or her ball with the intention to take free relief under Rule 16.1b (Abnormal Course Conditions), but then decides not to proceed under that Rule despite relief being available, the player's right to lift the ball under Rule 16.1b is no longer valid.

After lifting the ball but before doing anything else, the player has the following options:

  • Replace the ball in its original position with a penalty of one stroke (Rule 9.4b);
  • Replace the ball in its original position with a penalty of one stroke (Rule 9.4b) and then take relief under Rule 19.2 (Unplayable Ball Relief), getting an additional penalty of one stroke for a total of two penalty strokes;
  • Directly take relief under Rule 19.2b or c, without replacing the ball and using the spot where the original ball lay to determine the reference point for the relief procedure, getting a penalty of one stroke under Rule 19.2 and an additional penalty of one stroke under Rule 9.4b for a total of two penalty strokes;
  • Drop the ball under Rule 16.1b and then either play the ball as it lies without penalty or, using its new position to determine the reference point, take relief under any of the options of Rule 19.2, getting a penalty of only one stroke; or
  • Directly take stroke-and-distance relief, without dropping the ball under Rule 16.1b, getting a penalty of one stroke under Rule 19.2a and no penalty under Rule 9.4b, as the player does not need to establish a new reference point before taking relief under Rule 19.2a.

Ball Lifted or Moved by Opponent in Match Play
9.5b
Penalty for Lifting or Deliberately Touching Ball or Causing It to Move
9.5b/1
Player Declares Found Ball as His or Hers and This Causes Opponent to Lift Another Ball That Turns Out to Be the Player’s Ball

Under Rule 9.5b, an opponent gets one penalty stroke for lifting the player's ball unless one of the Exceptions applies.

For example, during a search Player A finds a ball and states that it is his or hers. Player B (the opponent) finds another ball and lifts it. Player A then realizes the found ball was not in fact his or her ball and the ball Player B lifted was Player A's ball.

Since the ball was not in fact found when Player B lifted Player A's ball, it is considered to have been accidentally moved during search and Exception 3 to Rule 9.5b applies. The player or opponent must replace the ball without penalty to anyone.

9.6
Ball Lifted or Moved by Outside Influence
9.6/1
Outside Influence Moved by Wind Causes Ball to Move

Wind is not itself an outside influence, but if wind causes an outside influence to move a player's ball, Rule 9.6 applies.

For example, if a player's ball comes to rest in a plastic bag (movable obstruction) that is lying on the ground, and a gust of wind blows the bag and moves the ball, the bag (outside influence) is considered to have moved the ball. The player may either:

  • Directly take relief under Rule 15.2a by estimating the point right under where the ball was at rest in the plastic bag before the ball was moved, or
  • Replace the ball moved by the bag by applying Rule 9.6 (by replacing the ball and the bag) and then decide to play the ball as it lies or take relief under Rule 15.2a (Relief From Movable Obstruction).
9.6/2
Where to Replace Ball When It Was Moved from Unknown Location

If a ball has been moved by an outside influence and the original spot where the ball lay is not known, the player must use his or her reasonable judgment (Rule 1.3b(2)) to determine where the ball had come to rest before it was moved.

For example, on a particular hole, part of the putting green and adjoining area cannot be seen by the players playing towards it. Near the putting green there is a bunker and a penalty area. A player plays towards the putting green and cannot tell where the ball came to rest. The players see a person (outside influence) with a ball. The person drops the ball and runs away. The player identifies it as his or her ball. The player does not know whether the ball was on the putting green, in the general area, in the bunker, or in the penalty area.

As it is impossible to know where the ball should be replaced, the player must use reasonable judgment. If it is equally likely the ball came to rest on the putting green, in the general area, in the bunker, or in the penalty area, a reasonable judgment would be to estimate the ball came to rest in the general area.

9.6/3
Player Learns That Ball Moved After Stroke Made

If it is not known or virtually certain that the player's ball has been moved by an outside influence, the player must play the ball as it lies. If information that the ball was in fact moved by an outside influence only becomes known to the player after the ball has been played, the player did not play from a wrong place because this knowledge did not exist when the player made the stroke.

9.6/4
Ball at Rest Played and then Discovered to Have Been Moved by Outside Influence; Ball Turns Out to be Wrong Ball

If a player discovers, after playing his or her ball, that it had been moved onto the course by an outside influence after the ball had come to rest out of bounds, the player has played a wrong ball (see Definition). Because it was not known or virtually certain at the time the ball was played, the player does not get a penalty for playing a wrong ball under Rule 6.3c(1) but might need to correct the mistake by proceeding under Rule 18.2b (What to Do When Ball Is Lost or Out of Bounds) depending when that discovery is made:

  • In match play, the player must correct the mistake if the discovery that the ball was moved onto the course by the outside influence is made before the opponent makes his or her next stroke or takes a similar action (such as conceding the hole).
    If that discovery occurs after the opponent makes his or her next stroke or takes a similar action, the player must continue to play out the hole with the wrong ball.
  • In stroke play, the player must correct the mistake if the discovery that the ball was moved onto the course by an outside influence is made before making a stroke to begin another hole or, for the final hole of the round, before returning his or her scorecard.
    If that discovery occurs after the player has made a stroke on the next hole or, for the final hole of the round, after returning his or her scorecard, the player’s score with the wrong ball counts.
Moved

When a ball at rest has left its original spot and come to rest on any other spot, and this can be seen by the naked eye (whether or not anyone actually sees it do so).

This applies whether the ball has gone up, down or horizontally in any direction away from its original spot.

If the ball only wobbles (sometimes referred to as oscillating) and stays on or returns to its original spot, the ball has not moved.

 

Interpretation Moved/1 - When Ball Resting on Object Has Moved

For the purpose of deciding whether a ball must be replaced or whether a player gets a penalty, a ball is treated as having moved only if it has moved in relation to a specific part of the larger condition or object it is resting on, unless the entire object the ball is resting on has moved in relation to the ground.

An example of when a ball has not moved includes when:

  • A ball is resting in the fork of a tree branch and the tree branch moves, but the ball's spot in the branch does not change.

Examples of when a ball has moved include when:

  • A ball is resting in a stationary plastic cup and the cup itself moves in relation to the ground because it is being blown by the wind.
  • A ball is resting in or on a stationary motorized cart that starts to move.

Interpretation Moved/2 - Television Evidence Shows Ball at Rest Changed Position but by Amount Not Reasonably Discernible to Naked Eye

When determining whether or not a ball at rest has moved, a player must make that judgment based on all the information reasonably available to him or her at the time, so that he or she can determine whether the ball must be replaced under the Rules. When the player's ball has left its original position and come to rest in another place by an amount that was not reasonably discernible to the naked eye at the time, a player's determination that the ball has not moved is conclusive, even if that determination is later shown to be incorrect through the use of sophisticated technology.

On the other hand, if the Committee determines, based on all of the evidence it has available, that the ball changed its position by an amount that was reasonably discernible to the naked eye at the time, the ball will be determined to have moved even though no-one actually saw it move.

Known or Virtually Certain

The standard for deciding what happened to a player’s ball – for example, whether the ball came to rest in a penalty area, whether it moved or what caused it to move.

Known or virtually certain means more than just possible or probable. It means that either:

  • There is conclusive evidence that the event in question happened to the player's ball, such as when the player or other witnesses saw it happen, or
  • Although there is a very small degree of doubt, all reasonably available information shows that it is at least 95% likely that the event in question happened.

"All reasonably available information" includes all information the player knows and all other information he or she can get with reasonable effort and without unreasonable delay.

 

Interpretation Known or Virtually Certain/1 - Applying "Known or Virtually Certain" Standard When Ball Moves

When it is not "known" what caused the ball to move, all reasonably available information must be considered and the evidence must be evaluated to determine if it is "virtually certain" that the player, opponent or outside influence caused the ball to move.

Depending on the circumstances, reasonably available information may include, but is not limited to:

  • The effect of any actions taken near the ball (such as movement of loose impediments, practice swings, grounding club and taking a stance),
  • Time elapsed between such actions and the movement of the ball,
  • The lie of the ball before it moved (such as on a fairway, perched on longer grass, on a surface imperfection or on the putting green),
  • The conditions of the ground near the ball (such as the degree of slope or presence of surface irregularities, etc), and
  • Wind speed and direction, rain and other weather conditions.

Interpretation Known or Virtually Certain/2 - Virtual Certainty Is Irrelevant if It Comes to Light After Three-Minute Search Expires

Determining whether there is knowledge or virtual certainty must be based on evidence known to the player at the time the three-minute search time expires.

Examples of when the player's later findings are irrelevant include when:

  • A player's tee shot comes to rest in an area containing heavy rough and a large animal hole. After a three-minute search, it is determined that it is not known or virtually certain that the ball is in the animal hole. As the player returns to the teeing area, the ball is found in the animal hole.
  • Even though the player has not yet put another ball in play, the player must take stroke-and-distance relief for a lost ball (Rule 18.2b - What to Do When Ball is Lost or Out of Bounds) since it was not known or virtually certain that the ball was in the animal hole, when the search time expired.
  • A player cannot find his or her ball and believes it may have been picked up by a spectator (outside influence), but there is not enough evidence to be virtually certain of this. A short time after the three-minute search time expires, a spectator is found to have the player's ball.

The player must take stroke-and-distance relief for a lost ball (Rule 18.2b) since the movement by the outside influence only became known after the search time expired.

Interpretation Known or Virtually Certain/3 - Player Unaware Ball Played by Another Player

It must be known or virtually certain that a player's ball has been played by another player as a wrong ball to treat it as being moved.

For example, in stroke play, Player A and Player B hit their tee shots into the same general location. Player A finds a ball and plays it. Player B goes forward to look for his or her ball and cannot find it. After three minutes, Player B starts back to the tee to play another ball. On the way, Player B finds Player A's ball and knows then that Player A has played his or her ball in error.

Player A gets the general penalty for playing a wrong ball and must then play his or her own ball (Rule 6.3c). Player A's ball was not lost even though both players searched for more than three minutes because Player A did not start searching for his or her ball; the searching was for Player B's ball. Regarding Player B's ball, Player B's original ball was lost and he or she must put another ball in play under penalty of stroke and distance (Rule 18.2b), because it was not known or virtually certain when the three-minute search time expired that the ball had been played by another player.

Moved

When a ball at rest has left its original spot and come to rest on any other spot, and this can be seen by the naked eye (whether or not anyone actually sees it do so).

This applies whether the ball has gone up, down or horizontally in any direction away from its original spot.

If the ball only wobbles (sometimes referred to as oscillating) and stays on or returns to its original spot, the ball has not moved.

 

Interpretation Moved/1 - When Ball Resting on Object Has Moved

For the purpose of deciding whether a ball must be replaced or whether a player gets a penalty, a ball is treated as having moved only if it has moved in relation to a specific part of the larger condition or object it is resting on, unless the entire object the ball is resting on has moved in relation to the ground.

An example of when a ball has not moved includes when:

  • A ball is resting in the fork of a tree branch and the tree branch moves, but the ball's spot in the branch does not change.

Examples of when a ball has moved include when:

  • A ball is resting in a stationary plastic cup and the cup itself moves in relation to the ground because it is being blown by the wind.
  • A ball is resting in or on a stationary motorized cart that starts to move.

"All reasonably available information" includes all information the player knows and all other information he or she can get with reasonable effort and without unreasonable delay.

 

Interpretation Known or Virtually Certain/1 - Applying "Known or Virtually Certain" Standard When Ball Moves

When it is not "known" what caused the ball to move, all reasonably available information must be considered and the evidence must be evaluated to determine if it is "virtually certain" that the player, opponent or outside influence caused the ball to move.

Depending on the circumstances, reasonably available information may include, but is not limited to:

  • The effect of any actions taken near the ball (such as movement of loose impediments, practice swings, grounding club and taking a stance),
  • Time elapsed between such actions and the movement of the ball,

  • A player's tee shot comes to rest in an area containing heavy rough and a large animal hole. After a three-minute search, it is determined that it is not known or virtually certain that the ball is in the animal hole. As the player returns to the teeing area, the ball is found in the animal hole.
  • Even though the player has not yet put another ball in play, the player must take stroke-and-distance relief for a lost ball (Rule 18.2b - What to Do When Ball is Lost or Out of Bounds) since it was not known or virtually certain that the ball was in the animal hole, when the search time expired.
  • A player cannot find his or her ball and believes it may have been picked up by a spectator (outside influence), but there is not enough evidence to be virtually certain of this. A short time after the three-minute search time expires, a spectator is found to have the player's ball.

The player must take stroke-and-distance relief for a lost ball (Rule 18.2b) since the movement by the outside influence only became known after the search time expired.

Interpretation Known or Virtually Certain/3 - Player Unaware Ball Played by Another Player

It must be known or virtually certain that a player's ball has been played by another player as a wrong ball to treat it as being moved.

For example, in stroke play, Player A and Player B hit their tee shots into the same general location. Player A finds a ball and plays it. Player B goes forward to look for his or her ball and cannot find it. After three minutes, Player B starts back to the tee to play another ball. On the way, Player B finds Player A's ball and knows then that Player A has played his or her ball in error.

Player A gets the general penalty for playing a wrong ball and must then play his or her own ball (Rule 6.3c). Player A's ball was not lost even though both players searched for more than three minutes because Player A did not start searching for his or her ball; the searching was for Player B's ball. Regarding Player B's ball, Player B's original ball was lost and he or she must put another ball in play under penalty of stroke and distance (Rule 18.2b), because it was not known or virtually certain when the three-minute search time expired that the ball had been played by another player.

Replace

To place a ball by setting it down and letting it go, with the intent for it to be in play.

If the player sets a ball down without intending it to be in play, the ball has not been replaced and is not in play (see Rule 14.4).

Whenever a Rule requires a ball to be replaced, the Rule identifies a specific spot where the ball must be replaced.

 

Interpretation Replace/1 - Ball May Not Be Replaced with a Club

For a ball to be replaced in a right way, it must be set down and let go. This means the player must use his or her hand to put the ball back in play on the spot it was lifted or moved from.

For example, if a player lifts his or her ball from the putting green and sets it aside, the player must not replace the ball by rolling it to the required spot with a club. If he or she does so, the ball is not replaced in the right way and the player gets one penalty stroke under Rule 14.2b(2) (How Ball Must Be Replaced) if the mistake is not corrected before the stroke is made.

Putting Green

The area on the hole the player is playing that:

  • Is specially prepared for putting, or
  • The Committee has defined as the putting green (such as when a temporary green is used).

The putting green for a hole contains the hole into which the player tries to play a ball. The putting green is one of the five defined areas of the course. The putting greens for all other holes (which the player is not playing at the time) are wrong greens and part of the general area.

The edge of a putting green is defined by where it can be seen that the specially prepared area starts (such as where the grass has been distinctly cut to show the edge), unless the Committee defines the edge in a different way (such as by using a line or dots).

If a double green is used for two different holes:

  • The entire prepared area containing both holes is treated as the putting green when playing each hole.

But the Committee may define an edge that divides the double green into two different putting greens, so that when a player is playing one of the holes, the part of the double green for the other hole is a wrong green.

Moved

When a ball at rest has left its original spot and come to rest on any other spot, and this can be seen by the naked eye (whether or not anyone actually sees it do so).

This applies whether the ball has gone up, down or horizontally in any direction away from its original spot.

If the ball only wobbles (sometimes referred to as oscillating) and stays on or returns to its original spot, the ball has not moved.

 

Interpretation Moved/1 - When Ball Resting on Object Has Moved

For the purpose of deciding whether a ball must be replaced or whether a player gets a penalty, a ball is treated as having moved only if it has moved in relation to a specific part of the larger condition or object it is resting on, unless the entire object the ball is resting on has moved in relation to the ground.

An example of when a ball has not moved includes when:

  • A ball is resting in the fork of a tree branch and the tree branch moves, but the ball's spot in the branch does not change.

Examples of when a ball has moved include when:

  • A ball is resting in a stationary plastic cup and the cup itself moves in relation to the ground because it is being blown by the wind.
  • A ball is resting in or on a stationary motorized cart that starts to move.

Interpretation Moved/2 - Television Evidence Shows Ball at Rest Changed Position but by Amount Not Reasonably Discernible to Naked Eye

When determining whether or not a ball at rest has moved, a player must make that judgment based on all the information reasonably available to him or her at the time, so that he or she can determine whether the ball must be replaced under the Rules. When the player's ball has left its original position and come to rest in another place by an amount that was not reasonably discernible to the naked eye at the time, a player's determination that the ball has not moved is conclusive, even if that determination is later shown to be incorrect through the use of sophisticated technology.

On the other hand, if the Committee determines, based on all of the evidence it has available, that the ball changed its position by an amount that was reasonably discernible to the naked eye at the time, the ball will be determined to have moved even though no-one actually saw it move.

Known or Virtually Certain

The standard for deciding what happened to a player’s ball – for example, whether the ball came to rest in a penalty area, whether it moved or what caused it to move.

Known or virtually certain means more than just possible or probable. It means that either:

  • There is conclusive evidence that the event in question happened to the player's ball, such as when the player or other witnesses saw it happen, or
  • Although there is a very small degree of doubt, all reasonably available information shows that it is at least 95% likely that the event in question happened.

"All reasonably available information" includes all information the player knows and all other information he or she can get with reasonable effort and without unreasonable delay.

 

Interpretation Known or Virtually Certain/1 - Applying "Known or Virtually Certain" Standard When Ball Moves

When it is not "known" what caused the ball to move, all reasonably available information must be considered and the evidence must be evaluated to determine if it is "virtually certain" that the player, opponent or outside influence caused the ball to move.

Depending on the circumstances, reasonably available information may include, but is not limited to:

  • The effect of any actions taken near the ball (such as movement of loose impediments, practice swings, grounding club and taking a stance),
  • Time elapsed between such actions and the movement of the ball,
  • The lie of the ball before it moved (such as on a fairway, perched on longer grass, on a surface imperfection or on the putting green),
  • The conditions of the ground near the ball (such as the degree of slope or presence of surface irregularities, etc), and
  • Wind speed and direction, rain and other weather conditions.

Interpretation Known or Virtually Certain/2 - Virtual Certainty Is Irrelevant if It Comes to Light After Three-Minute Search Expires

Determining whether there is knowledge or virtual certainty must be based on evidence known to the player at the time the three-minute search time expires.

Examples of when the player's later findings are irrelevant include when:

  • A player's tee shot comes to rest in an area containing heavy rough and a large animal hole. After a three-minute search, it is determined that it is not known or virtually certain that the ball is in the animal hole. As the player returns to the teeing area, the ball is found in the animal hole.
  • Even though the player has not yet put another ball in play, the player must take stroke-and-distance relief for a lost ball (Rule 18.2b - What to Do When Ball is Lost or Out of Bounds) since it was not known or virtually certain that the ball was in the animal hole, when the search time expired.
  • A player cannot find his or her ball and believes it may have been picked up by a spectator (outside influence), but there is not enough evidence to be virtually certain of this. A short time after the three-minute search time expires, a spectator is found to have the player's ball.

The player must take stroke-and-distance relief for a lost ball (Rule 18.2b) since the movement by the outside influence only became known after the search time expired.

Interpretation Known or Virtually Certain/3 - Player Unaware Ball Played by Another Player

It must be known or virtually certain that a player's ball has been played by another player as a wrong ball to treat it as being moved.

For example, in stroke play, Player A and Player B hit their tee shots into the same general location. Player A finds a ball and plays it. Player B goes forward to look for his or her ball and cannot find it. After three minutes, Player B starts back to the tee to play another ball. On the way, Player B finds Player A's ball and knows then that Player A has played his or her ball in error.

Player A gets the general penalty for playing a wrong ball and must then play his or her own ball (Rule 6.3c). Player A's ball was not lost even though both players searched for more than three minutes because Player A did not start searching for his or her ball; the searching was for Player B's ball. Regarding Player B's ball, Player B's original ball was lost and he or she must put another ball in play under penalty of stroke and distance (Rule 18.2b), because it was not known or virtually certain when the three-minute search time expired that the ball had been played by another player.

Moved

When a ball at rest has left its original spot and come to rest on any other spot, and this can be seen by the naked eye (whether or not anyone actually sees it do so).

On the other hand, if the Committee determines, based on all of the evidence it has available, that the ball changed its position by an amount that was reasonably discernible to the naked eye at the time, the ball will be determined to have moved even though no-one actually saw it move.

Replace

To place a ball by setting it down and letting it go, with the intent for it to be in play.

If the player sets a ball down without intending it to be in play, the ball has not been replaced and is not in play (see Rule 14.4).

Whenever a Rule requires a ball to be replaced, the Rule identifies a specific spot where the ball must be replaced.

 

Interpretation Replace/1 - Ball May Not Be Replaced with a Club

For a ball to be replaced in a right way, it must be set down and let go. This means the player must use his or her hand to put the ball back in play on the spot it was lifted or moved from.

For example, if a player lifts his or her ball from the putting green and sets it aside, the player must not replace the ball by rolling it to the required spot with a club. If he or she does so, the ball is not replaced in the right way and the player gets one penalty stroke under Rule 14.2b(2) (How Ball Must Be Replaced) if the mistake is not corrected before the stroke is made.

Known or Virtually Certain

The standard for deciding what happened to a player’s ball – for example, whether the ball came to rest in a penalty area, whether it moved or what caused it to move.

Known or virtually certain means more than just possible or probable. It means that either:

  • There is conclusive evidence that the event in question happened to the player's ball, such as when the player or other witnesses saw it happen, or

Putting Green

The area on the hole the player is playing that:

  • Is specially prepared for putting, or
  • The Committee has defined as the putting green (such as when a temporary green is used).

The putting green for a hole contains the hole into which the player tries to play a ball. The putting green is one of the five defined areas of the course. The putting greens for all other holes (which the player is not playing at the time) are wrong greens and part of the general area.

The edge of a putting green is defined by where it can be seen that the specially prepared area starts (such as where the grass has been distinctly cut to show the edge), unless the Committee defines the edge in a different way (such as by using a line or dots).

If a double green is used for two different holes:

  • The entire prepared area containing both holes is treated as the putting green when playing each hole.

But the Committee may define an edge that divides the double green into two different putting greens, so that when a player is playing one of the holes, the part of the double green for the other hole is a wrong green.

But the Committee may define an edge that divides the double green into two different putting greens, so that when a player is playing one of the holes, the part of the double green for the other hole is a wrong green.

Hole

The finishing point on the putting green for the hole being played:

  • The hole must be 4 ¼ inches (108 mm) in diameter and at least 4 inches (101.6 mm) deep.
  • If a lining is used, its outer diameter must not exceed 4 ¼ inches (108 mm). The lining must be sunk at least 1 inch (25.4 mm) below the putting green surface, unless the nature of the soil requires that it be closer to the surface.

The word “hole” (when not used as a Definition in italics) is used throughout the Rules to mean the part of the course associated with a particular teeing area, putting green and hole. Play of a hole begins from the teeing area and ends when the ball is holed on the putting green (or when the Rules otherwise say the hole is completed).

 

Stroke

The forward movement of the club made to strike the ball.

But a stroke has not been made if the player:

  • Decides during the downswing not to strike the ball and avoids doing so by deliberately stopping the clubhead before it reaches the ball or, if unable to stop, by deliberately missing the ball.
  • Accidentally strikes the ball when making a practice swing or while preparing to make a stroke.

When the Rules refer to "playing a ball," it means the same as making a stroke.

The player's score for a hole or a round is described as a number of "strokes" or "strokes taken," which means both all strokes made and any penalty strokes (see Rule 3.1c).

 

Interpretation Stroke/1 - Determining If a Stroke Was Made

If a player starts the downswing with a club intending to strike the ball, his or her action counts as a stroke when:

  • The clubhead is deflected or stopped by an outside influence (such as the branch of a tree) whether or not the ball is struck.
  • The clubhead separates from the shaft during the downswing and the player continues the downswing with the shaft alone, whether or not the ball is struck with the shaft.
  • The clubhead separates from the shaft during the downswing and the player continues the downswing with the shaft alone, with the clubhead falling and striking the ball.

The player's action does not count as a stroke in each of following situations:

  • During the downswing, a player's clubhead separates from the shaft. The player stops the downswing short of the ball, but the clubhead falls and strikes and moves the ball.
  • During the backswing, a player's clubhead separates from the shaft. The player completes the downswing with the shaft but does not strike the ball.
  • A ball is lodged in a tree branch beyond the reach of a club. If the player moves the ball by striking a lower part of the branch instead of the ball, Rule 9.4 (Ball Lifted or Moved by Player) applies.
Stroke

The forward movement of the club made to strike the ball.

But a stroke has not been made if the player:

  • Decides during the downswing not to strike the ball and avoids doing so by deliberately stopping the clubhead before it reaches the ball or, if unable to stop, by deliberately missing the ball.
  • Accidentally strikes the ball when making a practice swing or while preparing to make a stroke.

  • During the backswing, a player's clubhead separates from the shaft. The player completes the downswing with the shaft but does not strike the ball.
  • A ball is lodged in a tree branch beyond the reach of a club. If the player moves the ball by striking a lower part of the branch instead of the ball, Rule 9.4 (Ball Lifted or Moved by Player) applies.
Wrong Place

Any place on the course other than where the player is required or allowed to play his or her ball under the Rules.

Examples of playing from a wrong place are:

  • Playing a ball after replacing it on the wrong spot or without replacing it when required by the Rules.
  • Playing a dropped ball from outside the required relief area.
  • Taking relief under a wrong Rule, so that the ball is dropped in and played from a place not allowed under the Rules.
  • Playing a ball from a no play zone or when a no play zone interferes with the player’s area of intended stance or swing.

Playing a ball from outside the teeing area in starting play of a hole or in trying to correct that mistake is not playing from a wrong place (see Rule 6.1b).

Known or Virtually Certain

The standard for deciding what happened to a player’s ball – for example, whether the ball came to rest in a penalty area, whether it moved or what caused it to move.

Known or virtually certain means more than just possible or probable. It means that either:

  • There is conclusive evidence that the event in question happened to the player's ball, such as when the player or other witnesses saw it happen, or
  • Although there is a very small degree of doubt, all reasonably available information shows that it is at least 95% likely that the event in question happened.

"All reasonably available information" includes all information the player knows and all other information he or she can get with reasonable effort and without unreasonable delay.

 

Interpretation Known or Virtually Certain/1 - Applying "Known or Virtually Certain" Standard When Ball Moves

When it is not "known" what caused the ball to move, all reasonably available information must be considered and the evidence must be evaluated to determine if it is "virtually certain" that the player, opponent or outside influence caused the ball to move.

Depending on the circumstances, reasonably available information may include, but is not limited to:

  • The effect of any actions taken near the ball (such as movement of loose impediments, practice swings, grounding club and taking a stance),
  • Time elapsed between such actions and the movement of the ball,
  • The lie of the ball before it moved (such as on a fairway, perched on longer grass, on a surface imperfection or on the putting green),
  • The conditions of the ground near the ball (such as the degree of slope or presence of surface irregularities, etc), and
  • Wind speed and direction, rain and other weather conditions.

Interpretation Known or Virtually Certain/2 - Virtual Certainty Is Irrelevant if It Comes to Light After Three-Minute Search Expires

Determining whether there is knowledge or virtual certainty must be based on evidence known to the player at the time the three-minute search time expires.

Examples of when the player's later findings are irrelevant include when:

  • A player's tee shot comes to rest in an area containing heavy rough and a large animal hole. After a three-minute search, it is determined that it is not known or virtually certain that the ball is in the animal hole. As the player returns to the teeing area, the ball is found in the animal hole.
  • Even though the player has not yet put another ball in play, the player must take stroke-and-distance relief for a lost ball (Rule 18.2b - What to Do When Ball is Lost or Out of Bounds) since it was not known or virtually certain that the ball was in the animal hole, when the search time expired.
  • A player cannot find his or her ball and believes it may have been picked up by a spectator (outside influence), but there is not enough evidence to be virtually certain of this. A short time after the three-minute search time expires, a spectator is found to have the player's ball.

The player must take stroke-and-distance relief for a lost ball (Rule 18.2b) since the movement by the outside influence only became known after the search time expired.

Interpretation Known or Virtually Certain/3 - Player Unaware Ball Played by Another Player

It must be known or virtually certain that a player's ball has been played by another player as a wrong ball to treat it as being moved.

For example, in stroke play, Player A and Player B hit their tee shots into the same general location. Player A finds a ball and plays it. Player B goes forward to look for his or her ball and cannot find it. After three minutes, Player B starts back to the tee to play another ball. On the way, Player B finds Player A's ball and knows then that Player A has played his or her ball in error.

Player A gets the general penalty for playing a wrong ball and must then play his or her own ball (Rule 6.3c). Player A's ball was not lost even though both players searched for more than three minutes because Player A did not start searching for his or her ball; the searching was for Player B's ball.

Moved

When a ball at rest has left its original spot and come to rest on any other spot, and this can be seen by the naked eye (whether or not anyone actually sees it do so).

This applies whether the ball has gone up, down or horizontally in any direction away from its original spot.

If the ball only wobbles (sometimes referred to as oscillating) and stays on or returns to its original spot, the ball has not moved.

 

Interpretation Moved/1 - When Ball Resting on Object Has Moved

For the purpose of deciding whether a ball must be replaced or whether a player gets a penalty, a ball is treated as having moved only if it has moved in relation to a specific part of the larger condition or object it is resting on, unless the entire object the ball is resting on has moved in relation to the ground.

An example of when a ball has not moved includes when:

  • A ball is resting in the fork of a tree branch and the tree branch moves, but the ball's spot in the branch does not change.

Examples of when a ball has moved include when:

  • A ball is resting in a stationary plastic cup and the cup itself moves in relation to the ground because it is being blown by the wind.
  • A ball is resting in or on a stationary motorized cart that starts to move.

Interpretation Moved/2 - Television Evidence Shows Ball at Rest Changed Position but by Amount Not Reasonably Discernible to Naked Eye

When determining whether or not a ball at rest has moved, a player must make that judgment based on all the information reasonably available to him or her at the time, so that he or she can determine whether the ball must be replaced under the Rules. When the player's ball has left its original position and come to rest in another place by an amount that was not reasonably discernible to the naked eye at the time, a player's determination that the ball has not moved is conclusive, even if that determination is later shown to be incorrect through the use of sophisticated technology.

On the other hand, if the Committee determines, based on all of the evidence it has available, that the ball changed its position by an amount that was reasonably discernible to the naked eye at the time, the ball will be determined to have moved even though no-one actually saw it move.

Caddie

Someone who helps a player during a round, including in these ways:

  • Carrying, Transporting or Handling Clubs: A person who carries, transports (such as by cart or trolley) or handles a player’s clubs during play is the player’s caddie even if not named as a caddie by the player, except when done to move the player’s clubs, bag or cart out of the way or as a courtesy (such as getting a club the player left behind).
  • Giving Advice: A player’s caddie is the only person (other than a partner or partner’s caddie) a player may ask for advice.

A caddie may also help the player in other ways allowed by the Rules (see Rule 10.3b).

Partner

A player who competes together with another player as a side, in either match play or stroke play.

Moved

When a ball at rest has left its original spot and come to rest on any other spot, and this can be seen by the naked eye (whether or not anyone actually sees it do so).

This applies whether the ball has gone up, down or horizontally in any direction away from its original spot.

If the ball only wobbles (sometimes referred to as oscillating) and stays on or returns to its original spot, the ball has not moved.

General Area

The area of the course that covers all of the course except for the other four defined areas: (1) the teeing area the player must play from in starting the hole he or she is playing, (2) all penalty areas, (3) all bunkers, and (4) the putting green of the hole the player is playing.

The general area includes:

  • All teeing locations on the course other than the teeing area, and
  • All wrong greens.
Loose Impediment

Any unattached natural object such as:

  • Stones, loose grass, leaves, branches and sticks,
  • Dead animals and animal waste,
  • Worms, insects and similar animals that can be removed easily, and the mounds or webs they build (such as worm casts and ant hills), and
  • Clumps of compacted soil (including aeration plugs).

Such natural objects are not loose if they are:

  • Attached or growing,
  • Solidly embedded in the ground (that is, cannot be picked out easily), or
  • Sticking to the ball.

Special cases:

  • Sand and Loose Soil are not loose impediments.
  • Dew, Frost and Water are not loose impediments.
  • Snow and Natural Ice (other than frost) are either loose impediments or, when on the ground, temporary water, at the player's option.
  • Spider Webs are loose impediments even though they are attached to another object.

 

Interpretation Loose Impediment/1 - Status of Fruit

Fruit that is detached from its tree or bush is a loose impediment, even if the fruit is from a bush or tree not found on the course.

For example, fruit that has been partially eaten or cut into pieces, and the skin that has been peeled from a piece of fruit are loose impediments. But, when being carried by a player, it is his or her equipment.

Interpretation Loose Impediment/2 - When Loose Impediment Becomes Obstruction

Loose impediments may be transformed into obstructions through the processes of construction or manufacturing.

For example, a log (loose impediment) that has been split and had legs attached has been changed by construction into a bench (obstruction).

Interpretation Loose Impediment/3 - Status of Saliva

Saliva may be treated as either temporary water or a loose impediment, at the option of the player.

Interpretation Loose Impediment/4 - Loose Impediments Used to Surface a Road

Gravel is a loose impediment and a player may remove loose impediments under Rule 15.1a. This right is not affected by the fact that, when a road is covered with gravel, it becomes an artificially surfaced road, making it an immovable obstruction. The same principle applies to roads or paths constructed with stone, crushed shell, wood chips or the like.

In such a situation, the player may:

  • Play the ball as it lies on the obstruction and remove gravel (loose impediment) from the road (Rule 15.1a).
  • Take relief without penalty from the abnormal course condition (immovable obstruction) (Rule 16.1b).

The player may also remove some gravel from the road to determine the possibility of playing the ball as it lies before choosing to take free relief.

Interpretation Loose Impediment/5 - Living Insect Is Never Sticking to a Ball

Although dead insects may be considered to be sticking to a ball, living insects are never considered to be sticking to a ball, whether they are stationary or moving. Therefore, live insects on a ball are loose impediments.

Moved

When a ball at rest has left its original spot and come to rest on any other spot, and this can be seen by the naked eye (whether or not anyone actually sees it do so).

This applies whether the ball has gone up, down or horizontally in any direction away from its original spot.

If the ball only wobbles (sometimes referred to as oscillating) and stays on or returns to its original spot, the ball has not moved.

 

Interpretation Moved/1 - When Ball Resting on Object Has Moved

For the purpose of deciding whether a ball must be replaced or whether a player gets a penalty, a ball is treated as having moved only if it has moved in relation to a specific part of the larger condition or object it is resting on, unless the entire object the ball is resting on has moved in relation to the ground.

An example of when a ball has not moved includes when:

  • A ball is resting in the fork of a tree branch and the tree branch moves, but the ball's spot in the branch does not change.

Examples of when a ball has moved include when:

  • A ball is resting in a stationary plastic cup and the cup itself moves in relation to the ground because it is being blown by the wind.
  • A ball is resting in or on a stationary motorized cart that starts to move.

Interpretation Moved/2 - Television Evidence Shows Ball at Rest Changed Position but by Amount Not Reasonably Discernible to Naked Eye

When determining whether or not a ball at rest has moved, a player must make that judgment based on all the information reasonably available to him or her at the time, so that he or she can determine whether the ball must be replaced under the Rules. When the player's ball has left its original position and come to rest in another place by an amount that was not reasonably discernible to the naked eye at the time, a player's determination that the ball has not moved is conclusive, even if that determination is later shown to be incorrect through the use of sophisticated technology.

On the other hand, if the Committee determines, based on all of the evidence it has available, that the ball changed its position by an amount that was reasonably discernible to the naked eye at the time, the ball will be determined to have moved even though no-one actually saw it move.

On the other hand, if the Committee determines, based on all of the evidence it has available, that the ball changed its position by an amount that was reasonably discernible to the naked eye at the time, the ball will be determined to have moved even though no-one actually saw it move.

Replace

To place a ball by setting it down and letting it go, with the intent for it to be in play.

If the player sets a ball down without intending it to be in play, the ball has not been replaced and is not in play (see Rule 14.4).

Whenever a Rule requires a ball to be replaced, the Rule identifies a specific spot where the ball must be replaced.

 

Interpretation Replace/1 - Ball May Not Be Replaced with a Club

For a ball to be replaced in a right way, it must be set down and let go. This means the player must use his or her hand to put the ball back in play on the spot it was lifted or moved from.

For example, if a player lifts his or her ball from the putting green and sets it aside, the player must not replace the ball by rolling it to the required spot with a club. If he or she does so, the ball is not replaced in the right way and the player gets one penalty stroke under Rule 14.2b(2) (How Ball Must Be Replaced) if the mistake is not corrected before the stroke is made.

Caddie

Someone who helps a player during a round, including in these ways:

  • Carrying, Transporting or Handling Clubs: A person who carries, transports (such as by cart or trolley) or handles a player’s clubs during play is the player’s caddie even if not named as a caddie by the player, except when done to move the player’s clubs, bag or cart out of the way or as a courtesy (such as getting a club the player left behind).
  • Giving Advice: A player’s caddie is the only person (other than a partner or partner’s caddie) a player may ask for advice.

A caddie may also help the player in other ways allowed by the Rules (see Rule 10.3b).

Partner

A player who competes together with another player as a side, in either match play or stroke play.

Moved

When a ball at rest has left its original spot and come to rest on any other spot, and this can be seen by the naked eye (whether or not anyone actually sees it do so).

This applies whether the ball has gone up, down or horizontally in any direction away from its original spot.

If the ball only wobbles (sometimes referred to as oscillating) and stays on or returns to its original spot, the ball has not moved.

Stroke

The forward movement of the club made to strike the ball.

But a stroke has not been made if the player:

  • Decides during the downswing not to strike the ball and avoids doing so by deliberately stopping the clubhead before it reaches the ball or, if unable to stop, by deliberately missing the ball.
  • Accidentally strikes the ball when making a practice swing or while preparing to make a stroke.

When the Rules refer to "playing a ball," it means the same as making a stroke.

The player's score for a hole or a round is described as a number of "strokes" or "strokes taken," which means both all strokes made and any penalty strokes (see Rule 3.1c).

 

Interpretation Stroke/1 - Determining If a Stroke Was Made

If a player starts the downswing with a club intending to strike the ball, his or her action counts as a stroke when:

  • The clubhead is deflected or stopped by an outside influence (such as the branch of a tree) whether or not the ball is struck.
  • The clubhead separates from the shaft during the downswing and the player continues the downswing with the shaft alone, whether or not the ball is struck with the shaft.
  • The clubhead separates from the shaft during the downswing and the player continues the downswing with the shaft alone, with the clubhead falling and striking the ball.

The player's action does not count as a stroke in each of following situations:

  • During the downswing, a player's clubhead separates from the shaft. The player stops the downswing short of the ball, but the clubhead falls and strikes and moves the ball.
  • During the backswing, a player's clubhead separates from the shaft. The player completes the downswing with the shaft but does not strike the ball.
  • A ball is lodged in a tree branch beyond the reach of a club. If the player moves the ball by striking a lower part of the branch instead of the ball, Rule 9.4 (Ball Lifted or Moved by Player) applies.
Moved

When a ball at rest has left its original spot and come to rest on any other spot, and this can be seen by the naked eye (whether or not anyone actually sees it do so).

This applies whether the ball has gone up, down or horizontally in any direction away from its original spot.

If the ball only wobbles (sometimes referred to as oscillating) and stays on or returns to its original spot, the ball has not moved.

  • During the backswing, a player's clubhead separates from the shaft. The player completes the downswing with the shaft but does not strike the ball.
  • A ball is lodged in a tree branch beyond the reach of a club. If the player moves the ball by striking a lower part of the branch instead of the ball, Rule 9.4 (Ball Lifted or Moved by Player) applies.
Replace

To place a ball by setting it down and letting it go, with the intent for it to be in play.

If the player sets a ball down without intending it to be in play, the ball has not been replaced and is not in play (see Rule 14.4).

Whenever a Rule requires a ball to be replaced, the Rule identifies a specific spot where the ball must be replaced.

 

Interpretation Replace/1 - Ball May Not Be Replaced with a Club

For a ball to be replaced in a right way, it must be set down and let go. This means the player must use his or her hand to put the ball back in play on the spot it was lifted or moved from.

For example, if a player lifts his or her ball from the putting green and sets it aside, the player must not replace the ball by rolling it to the required spot with a club. If he or she does so, the ball is not replaced in the right way and the player gets one penalty stroke under Rule 14.2b(2) (How Ball Must Be Replaced) if the mistake is not corrected before the stroke is made.

General Penalty

Loss of hole in match play or two penalty strokes in stroke play.

Wrong Place

Any place on the course other than where the player is required or allowed to play his or her ball under the Rules.

Examples of playing from a wrong place are:

  • Playing a ball after replacing it on the wrong spot or without replacing it when required by the Rules.
  • Playing a dropped ball from outside the required relief area.
  • Taking relief under a wrong Rule, so that the ball is dropped in and played from a place not allowed under the Rules.
  • Playing a ball from a no play zone or when a no play zone interferes with the player’s area of intended stance or swing.

Playing a ball from outside the teeing area in starting play of a hole or in trying to correct that mistake is not playing from a wrong place (see Rule 6.1b).

In Play

The status of a player’s ball when it lies on the course and is being used in the play of a hole:

  • A ball first becomes in play on a hole:
    • When the player makes a stroke at it from inside the teeing area, or
    • In match play, when the player makes a stroke at it from outside the teeing area and the opponent does not cancel the stroke under Rule 6.1b.
  • That ball remains in play until it is holed, except that it is no longer in play:
    • When it is lifted from the course,
    • When it is lost (even if it is at rest on the course) or comes to rest out of bounds, or
    • When another ball has been substituted for it, even if not allowed by a Rule.

A ball that is not in play is a wrong ball.

The player cannot have more than one ball in play at any time. (See Rule 6.3d for the limited cases when a player may play more than one ball at the same time on a hole.)

When the Rules refer to a ball at rest or in motion, this means a ball that is in play.

When a ball-marker is in place to mark the spot of a ball in play:

  • If the ball has not been lifted, it is still in play, and
  • If the ball has been lifted and replaced, it is in play even if the ball-marker has not been removed.
Course

The entire area of play within the edge of any boundaries set by the Committee:

  • All areas inside the boundary edge are in bounds and part of the course.
  • All areas outside the boundary edge are out of bounds and not part of the course.
  • The boundary edge extends both up above the ground and down below the ground.

The course is made up of the five defined areas of the course.

Moved

When a ball at rest has left its original spot and come to rest on any other spot, and this can be seen by the naked eye (whether or not anyone actually sees it do so).

This applies whether the ball has gone up, down or horizontally in any direction away from its original spot.

If the ball only wobbles (sometimes referred to as oscillating) and stays on or returns to its original spot, the ball has not moved.

 

Interpretation Moved/1 - When Ball Resting on Object Has Moved

For the purpose of deciding whether a ball must be replaced or whether a player gets a penalty, a ball is treated as having moved only if it has moved in relation to a specific part of the larger condition or object it is resting on, unless the entire object the ball is resting on has moved in relation to the ground.

An example of when a ball has not moved includes when:

  • A ball is resting in the fork of a tree branch and the tree branch moves, but the ball's spot in the branch does not change.

Examples of when a ball has moved include when:

  • A ball is resting in a stationary plastic cup and the cup itself moves in relation to the ground because it is being blown by the wind.
  • A ball is resting in or on a stationary motorized cart that starts to move.

To place a ball by setting it down and letting it go, with the intent for it to be in play.

If the player sets a ball down without intending it to be in play, the ball has not been replaced and is not in play (see Rule 14.4).

Whenever a Rule requires a ball to be replaced, the Rule identifies a specific spot where the ball must be replaced.

 

Interpretation Replace/1 - Ball May Not Be Replaced with a Club

For a ball to be replaced in a right way, it must be set down and let go. This means the player must use his or her hand to put the ball back in play on the spot it was lifted or moved from.

For example, if a player lifts his or her ball from the putting green and sets it aside, the player must not replace the ball by rolling it to the required spot with a club. If he or she does so, the ball is not replaced in the right way and the player gets one penalty stroke under Rule 14.2b(2) (How Ball Must Be Replaced) if the mistake is not corrected before the stroke is made.

General Area

The area of the course that covers all of the course except for the other four defined areas: (1) the teeing area the player must play from in starting the hole he or she is playing, (2) all penalty areas, (3) all bunkers, and (4) the putting green of the hole the player is playing.

The general area includes:

  • All teeing locations on the course other than the teeing area, and
  • All wrong greens.
Moved

When the player's ball has left its original position and come to rest in another place by an amount that was not reasonably discernible to the naked eye at the time, a player's determination that the ball has not moved is conclusive, even if that determination is later shown to be incorrect through the use of sophisticated technology.

On the other hand, if the Committee determines, based on all of the evidence it has available, that the ball changed its position by an amount that was reasonably discernible to the naked eye at the time, the ball will be determined to have moved even though no-one actually saw it move.

Moved

When a ball at rest has left its original spot and come to rest on any other spot, and this can be seen by the naked eye (whether or not anyone actually sees it do so).

This applies whether the ball has gone up, down or horizontally in any direction away from its original spot.

If the ball only wobbles (sometimes referred to as oscillating) and stays on or returns to its original spot, the ball has not moved.

 

Interpretation Moved/1 - When Ball Resting on Object Has Moved

For the purpose of deciding whether a ball must be replaced or whether a player gets a penalty, a ball is treated as having moved only if it has moved in relation to a specific part of the larger condition or object it is resting on, unless the entire object the ball is resting on has moved in relation to the ground.

An example of when a ball has not moved includes when:

  • A ball is resting in the fork of a tree branch and the tree branch moves, but the ball's spot in the branch does not change.

Examples of when a ball has moved include when:

  • A ball is resting in a stationary plastic cup and the cup itself moves in relation to the ground because it is being blown by the wind.
  • A ball is resting in or on a stationary motorized cart that starts to move.

Stroke

The forward movement of the club made to strike the ball.

But a stroke has not been made if the player:

  • Decides during the downswing not to strike the ball and avoids doing so by deliberately stopping the clubhead before it reaches the ball or, if unable to stop, by deliberately missing the ball.
  • Accidentally strikes the ball when making a practice swing or while preparing to make a stroke.

When the Rules refer to "playing a ball," it means the same as making a stroke.

The player's score for a hole or a round is described as a number of "strokes" or "strokes taken," which means both all strokes made and any penalty strokes (see Rule 3.1c).

 

Interpretation Stroke/1 - Determining If a Stroke Was Made

If a player starts the downswing with a club intending to strike the ball, his or her action counts as a stroke when:

  • The clubhead is deflected or stopped by an outside influence (such as the branch of a tree) whether or not the ball is struck.
  • The clubhead separates from the shaft during the downswing and the player continues the downswing with the shaft alone, whether or not the ball is struck with the shaft.
  • The clubhead separates from the shaft during the downswing and the player continues the downswing with the shaft alone, with the clubhead falling and striking the ball.

The player's action does not count as a stroke in each of following situations:

  • During the downswing, a player's clubhead separates from the shaft. The player stops the downswing short of the ball, but the clubhead falls and strikes and moves the ball.
  • During the backswing, a player's clubhead separates from the shaft. The player completes the downswing with the shaft but does not strike the ball.
  • A ball is lodged in a tree branch beyond the reach of a club. If the player moves the ball by striking a lower part of the branch instead of the ball, Rule 9.4 (Ball Lifted or Moved by Player) applies.
Moved

When a ball at rest has left its original spot and come to rest on any other spot, and this can be seen by the naked eye (whether or not anyone actually sees it do so).

This applies whether the ball has gone up, down or horizontally in any direction away from its original spot.

If the ball only wobbles (sometimes referred to as oscillating) and stays on or returns to its original spot, the ball has not moved.

Replace

To place a ball by setting it down and letting it go, with the intent for it to be in play.

If the player sets a ball down without intending it to be in play, the ball has not been replaced and is not in play (see Rule 14.4).

Whenever a Rule requires a ball to be replaced, the Rule identifies a specific spot where the ball must be replaced.

 

Interpretation Replace/1 - Ball May Not Be Replaced with a Club

For a ball to be replaced in a right way, it must be set down and let go. This means the player must use his or her hand to put the ball back in play on the spot it was lifted or moved from.

For example, if a player lifts his or her ball from the putting green and sets it aside, the player must not replace the ball by rolling it to the required spot with a club. If he or she does so, the ball is not replaced in the right way and the player gets one penalty stroke under Rule 14.2b(2) (How Ball Must Be Replaced) if the mistake is not corrected before the stroke is made.

In Play

The status of a player’s ball when it lies on the course and is being used in the play of a hole:

  • A ball first becomes in play on a hole:
    • When the player makes a stroke at it from inside the teeing area, or
    • In match play, when the player makes a stroke at it from outside the teeing area and the opponent does not cancel the stroke under Rule 6.1b.
  • That ball remains in play until it is holed, except that it is no longer in play:
    • When it is lifted from the course,
    • When it is lost (even if it is at rest on the course) or comes to rest out of bounds, or
    • When another ball has been substituted for it, even if not allowed by a Rule.

A ball that is not in play is a wrong ball.

The player cannot have more than one ball in play at any time. (See Rule 6.3d for the limited cases when a player may play more than one ball at the same time on a hole.)

When the Rules refer to a ball at rest or in motion, this means a ball that is in play.

When a ball-marker is in place to mark the spot of a ball in play:

  • If the ball has not been lifted, it is still in play, and
  • If the ball has been lifted and replaced, it is in play even if the ball-marker has not been removed.
Moved

When a ball at rest has left its original spot and come to rest on any other spot, and this can be seen by the naked eye (whether or not anyone actually sees it do so).

This applies whether the ball has gone up, down or horizontally in any direction away from its original spot.

If the ball only wobbles (sometimes referred to as oscillating) and stays on or returns to its original spot, the ball has not moved.

 

Interpretation Moved/1 - When Ball Resting on Object Has Moved

For the purpose of deciding whether a ball must be replaced or whether a player gets a penalty, a ball is treated as having moved only if it has moved in relation to a specific part of the larger condition or object it is resting on, unless the entire object the ball is resting on has moved in relation to the ground.

  • A ball is resting in a stationary plastic cup and the cup itself moves in relation to the ground because it is being blown by the wind.
  • A ball is resting in or on a stationary motorized cart that starts to move.

On the other hand, if the Committee determines, based on all of the evidence it has available, that the ball changed its position by an amount that was reasonably discernible to the naked eye at the time, the ball will be determined to have moved even though no-one actually saw it move.

Mark

To show the spot where a ball is at rest by either:

  • Placing a ball-marker right behind or right next to the ball, or
  • Holding a club on the ground right behind or right next to the ball.

This is done to show the spot where the ball must be replaced after it is lifted.

Putting Green

The area on the hole the player is playing that:

  • Is specially prepared for putting, or
  • The Committee has defined as the putting green (such as when a temporary green is used).

The putting green for a hole contains the hole into which the player tries to play a ball. The putting green is one of the five defined areas of the course. The putting greens for all other holes (which the player is not playing at the time) are wrong greens and part of the general area.

The edge of a putting green is defined by where it can be seen that the specially prepared area starts (such as where the grass has been distinctly cut to show the edge), unless the Committee defines the edge in a different way (such as by using a line or dots).

If a double green is used for two different holes:

  • The entire prepared area containing both holes is treated as the putting green when playing each hole.

But the Committee may define an edge that divides the double green into two different putting greens, so that when a player is playing one of the holes, the part of the double green for the other hole is a wrong green.

Hole

The finishing point on the putting green for the hole being played:

  • The hole must be 4 ¼ inches (108 mm) in diameter and at least 4 inches (101.6 mm) deep.
  • If a lining is used, its outer diameter must not exceed 4 ¼ inches (108 mm). The lining must be sunk at least 1 inch (25.4 mm) below the putting green surface, unless the nature of the soil requires that it be closer to the surface.

The word “hole” (when not used as a Definition in italics) is used throughout the Rules to mean the part of the course associated with a particular teeing area, putting green and hole. Play of a hole begins from the teeing area and ends when the ball is holed on the putting green (or when the Rules otherwise say the hole is completed).

 

Mark

To show the spot where a ball is at rest by either:

  • Placing a ball-marker right behind or right next to the ball, or
  • Holding a club on the ground right behind or right next to the ball.

This is done to show the spot where the ball must be replaced after it is lifted.

Mark

To show the spot where a ball is at rest by either:

  • Placing a ball-marker right behind or right next to the ball, or
  • Holding a club on the ground right behind or right next to the ball.

This is done to show the spot where the ball must be replaced after it is lifted.

Course

The entire area of play within the edge of any boundaries set by the Committee:

  • All areas inside the boundary edge are in bounds and part of the course.
  • All areas outside the boundary edge are out of bounds and not part of the course.
  • The boundary edge extends both up above the ground and down below the ground.

The course is made up of the five defined areas of the course.

Stroke

The forward movement of the club made to strike the ball.

But a stroke has not been made if the player:

  • Decides during the downswing not to strike the ball and avoids doing so by deliberately stopping the clubhead before it reaches the ball or, if unable to stop, by deliberately missing the ball.
  • Accidentally strikes the ball when making a practice swing or while preparing to make a stroke.

  • The clubhead is deflected or stopped by an outside influence (such as the branch of a tree) whether or not the ball is struck.
  • The clubhead separates from the shaft during the downswing and the player continues the downswing with the shaft alone, whether or not the ball is struck with the shaft.
  • The clubhead separates from the shaft during the downswing and the player continues the downswing with the shaft alone, with the clubhead falling and striking the ball.

The player's action does not count as a stroke in each of following situations:

  • During the downswing, a player's clubhead separates from the shaft. The player stops the downswing short of the ball, but the clubhead falls and strikes and moves the ball.
  • During the backswing, a player's clubhead separates from the shaft. The player completes the downswing with the shaft but does not strike the ball.
  • A ball is lodged in a tree branch beyond the reach of a club. If the player moves the ball by striking a lower part of the branch instead of the ball, Rule 9.4 (Ball Lifted or Moved by Player) applies.
Moved

When a ball at rest has left its original spot and come to rest on any other spot, and this can be seen by the naked eye (whether or not anyone actually sees it do so).

This applies whether the ball has gone up, down or horizontally in any direction away from its original spot.

If the ball only wobbles (sometimes referred to as oscillating) and stays on or returns to its original spot, the ball has not moved.

 

Interpretation Moved/1 - When Ball Resting on Object Has Moved

For the purpose of deciding whether a ball must be replaced or whether a player gets a penalty, a ball is treated as having moved only if it has moved in relation to a specific part of the larger condition or object it is resting on, unless the entire object the ball is resting on has moved in relation to the ground.

An example of when a ball has not moved includes when:

  • A ball is resting in the fork of a tree branch and the tree branch moves, but the ball's spot in the branch does not change.

Examples of when a ball has moved include when:

  • A ball is resting in a stationary plastic cup and the cup itself moves in relation to the ground because it is being blown by the wind.
  • A ball is resting in or on a stationary motorized cart that starts to move.

Loose Impediment

Any unattached natural object such as:

  • Stones, loose grass, leaves, branches and sticks,
  • Dead animals and animal waste,
  • Worms, insects and similar animals that can be removed easily, and the mounds or webs they build (such as worm casts and ant hills), and
  • Clumps of compacted soil (including aeration plugs).

Such natural objects are not loose if they are:

  • Attached or growing,
  • Solidly embedded in the ground (that is, cannot be picked out easily), or
  • Sticking to the ball.

Special cases:

  • Sand and Loose Soil are not loose impediments.
  • Dew, Frost and Water are not loose impediments.
  • Snow and Natural Ice (other than frost) are either loose impediments or, when on the ground, temporary water, at the player's option.
  • Spider Webs are loose impediments even though they are attached to another object.

 

Interpretation Loose Impediment/1 - Status of Fruit

Fruit that is detached from its tree or bush is a loose impediment, even if the fruit is from a bush or tree not found on the course.

For example, fruit that has been partially eaten or cut into pieces, and the skin that has been peeled from a piece of fruit are loose impediments. But, when being carried by a player, it is his or her equipment.

Interpretation Loose Impediment/2 - When Loose Impediment Becomes Obstruction

Loose impediments may be transformed into obstructions through the processes of construction or manufacturing.

For example, a log (loose impediment) that has been split and had legs attached has been changed by construction into a bench (obstruction).

Interpretation Loose Impediment/3 - Status of Saliva

Saliva may be treated as either temporary water or a loose impediment, at the option of the player.

Interpretation Loose Impediment/4 - Loose Impediments Used to Surface a Road

Gravel is a loose impediment and a player may remove loose impediments under Rule 15.1a. This right is not affected by the fact that, when a road is covered with gravel, it becomes an artificially surfaced road, making it an immovable obstruction. The same principle applies to roads or paths constructed with stone, crushed shell, wood chips or the like.

In such a situation, the player may:

  • Play the ball as it lies on the obstruction and remove gravel (loose impediment) from the road (Rule 15.1a).
  • Take relief without penalty from the abnormal course condition (immovable obstruction) (Rule 16.1b).

The player may also remove some gravel from the road to determine the possibility of playing the ball as it lies before choosing to take free relief.

Interpretation Loose Impediment/5 - Living Insect Is Never Sticking to a Ball

Although dead insects may be considered to be sticking to a ball, living insects are never considered to be sticking to a ball, whether they are stationary or moving. Therefore, live insects on a ball are loose impediments.

Teeing Area

The area the player must play from in starting the hole he or she is playing.

The teeing area is a rectangle that is two club-lengths deep where:

  • The front edge is defined by the line between the forward-most points of two tee-markers set by the Committee, and
  • The side edges are defined by the lines back from the outside points of the tee-markers.

The teeing area is one of the five defined areas of the course.

All other teeing locations on the course (whether on the same hole or any other hole) are part of the general area.

Moved

When a ball at rest has left its original spot and come to rest on any other spot, and this can be seen by the naked eye (whether or not anyone actually sees it do so).

This applies whether the ball has gone up, down or horizontally in any direction away from its original spot.

If the ball only wobbles (sometimes referred to as oscillating) and stays on or returns to its original spot, the ball has not moved.

 

Interpretation Moved/1 - When Ball Resting on Object Has Moved

For the purpose of deciding whether a ball must be replaced or whether a player gets a penalty, a ball is treated as having moved only if it has moved in relation to a specific part of the larger condition or object it is resting on, unless the entire object the ball is resting on has moved in relation to the ground.

Committee

The person or group in charge of the competition or the course.

See Committee Procedures, Section 1 (explaining the role of the Committee).

Moved

When a ball at rest has left its original spot and come to rest on any other spot, and this can be seen by the naked eye (whether or not anyone actually sees it do so).

This applies whether the ball has gone up, down or horizontally in any direction away from its original spot.

If the ball only wobbles (sometimes referred to as oscillating) and stays on or returns to its original spot, the ball has not moved.

 

Interpretation Moved/1 - When Ball Resting on Object Has Moved

For the purpose of deciding whether a ball must be replaced or whether a player gets a penalty, a ball is treated as having moved only if it has moved in relation to a specific part of the larger condition or object it is resting on, unless the entire object the ball is resting on has moved in relation to the ground.

An example of when a ball has not moved includes when:

  • A ball is resting in the fork of a tree branch and the tree branch moves, but the ball's spot in the branch does not change.

Examples of when a ball has moved include when:

  • A ball is resting in a stationary plastic cup and the cup itself moves in relation to the ground because it is being blown by the wind.
  • A ball is resting in or on a stationary motorized cart that starts to move.

Interpretation Moved/2 - Television Evidence Shows Ball at Rest Changed Position but by Amount Not Reasonably Discernible to Naked Eye

When determining whether or not a ball at rest has moved, a player must make that judgment based on all the information reasonably available to him or her at the time, so that he or she can determine whether the ball must be replaced under the Rules. When the player's ball has left its original position and come to rest in another place by an amount that was not reasonably discernible to the naked eye at the time, a player's determination that the ball has not moved is conclusive, even if that determination is later shown to be incorrect through the use of sophisticated technology.

On the other hand, if the Committee determines, based on all of the evidence it has available, that the ball changed its position by an amount that was reasonably discernible to the naked eye at the time, the ball will be determined to have moved even though no-one actually saw it move.

In Play

The status of a player’s ball when it lies on the course and is being used in the play of a hole:

  • A ball first becomes in play on a hole:
    • When the player makes a stroke at it from inside the teeing area, or
    • In match play, when the player makes a stroke at it from outside the teeing area and the opponent does not cancel the stroke under Rule 6.1b.
  • That ball remains in play until it is holed, except that it is no longer in play:
    • When it is lifted from the course,
    • When it is lost (even if it is at rest on the course) or comes to rest out of bounds, or
    • When another ball has been substituted for it, even if not allowed by a Rule.

A ball that is not in play is a wrong ball.

The player cannot have more than one ball in play at any time. (See Rule 6.3d for the limited cases when a player may play more than one ball at the same time on a hole.)

When the Rules refer to a ball at rest or in motion, this means a ball that is in play.

When a ball-marker is in place to mark the spot of a ball in play:

  • If the ball has not been lifted, it is still in play, and
  • If the ball has been lifted and replaced, it is in play even if the ball-marker has not been removed.

Mark

To show the spot where a ball is at rest by either:

  • Placing a ball-marker right behind or right next to the ball, or
  • Holding a club on the ground right behind or right next to the ball.

This is done to show the spot where the ball must be replaced after it is lifted.

Drop

To hold the ball and let go of it so that it falls through the air, with the intent for the ball to be in play.

If the player lets go of a ball without intending it to be in play, the ball has not been dropped and is not in play (see Rule 14.4).

Each relief Rule identifies a specific relief area where the ball must be dropped and come to rest.

In taking relief, the player must let go of the ball from a location at knee height so that the ball:

  • Falls straight down, without the player throwing, spinning or rolling it or using any other motion that might affect where the ball will come to rest, and
  • Does not touch any part of the player’s body or equipment before it hits the ground (see Rule 14.3b).
Tee

An object used to raise a ball above the ground to play it from the teeing area. It must be no longer than four inches (101.6 mm) and conform with the Equipment Rules.

Relief Area

The area where a player must drop a ball when taking relief under a Rule. Each relief Rule requires the player to use a specific relief area whose size and location are based on these three factors:

  • Reference Point: The point from which the size of relief area is measured.
  • Size of Relief Area Measured from Reference Point: The relief area is either one or two club-lengths from the reference point, but with certain limits:
  • Limits on Location of Relief Area: The location of the relief area may be limited in one or more ways so that, for example:
    • It is only in certain defined areas of the course, such as only in the general area, or not in a bunker or a penalty area,
    • It is not nearer the hole than the reference point or must be outside a penalty area or a bunker from which relief is being taken, or
    • It is where there is no interference (as defined in the particular Rule) from the condition from which relief is being taken.

In using club-lengths to determine the size of a relief area, the player may measure directly across a ditch, hole or similar thing, and directly across or through an object (such as a tree, fence, wall, tunnel, drain or sprinkler head), but is not allowed to measure through ground that naturally slopes up and down.

See Committee Procedures, Section 2I (Committee may choose to allow or require the player to use a dropping zone as a relief area when taking certain relief).

Moved

When a ball at rest has left its original spot and come to rest on any other spot, and this can be seen by the naked eye (whether or not anyone actually sees it do so).

This applies whether the ball has gone up, down or horizontally in any direction away from its original spot.

If the ball only wobbles (sometimes referred to as oscillating) and stays on or returns to its original spot, the ball has not moved.

Movable Obstruction

An obstruction that can be moved with reasonable effort and without damaging the obstruction or the course.

If part of an immovable obstruction or integral object (such as a gate or door or part of an attached cable) meets these two standards, that part is treated as a movable obstruction.

But this does not apply if the movable part of an immovable obstruction or integral object is not meant to be moved (such as a loose stone that is part of a stone wall).

Even when an obstruction is movable, the Committee may define it to be an immovable obstruction.

    • In match play, when the player makes a stroke at it from outside the teeing area and the opponent does not cancel the stroke under Rule 6.1b.
  • That ball remains in play until it is holed, except that it is no longer in play:
    • When it is lifted from the course,
    • When it is lost (even if it is at rest on the course) or comes to rest out of bounds, or
    • When another ball has been substituted for it, even if not allowed by a Rule.

A ball that is not in play is a wrong ball.

The player cannot have more than one ball in play at any time. (See Rule 6.3d for the limited cases when a player may play more than one ball at the same time on a hole.)

When the Rules refer to a ball at rest or in motion, this means a ball that is in play.

When a ball-marker is in place to mark the spot of a ball in play:

  • If the ball has not been lifted, it is still in play, and
  • If the ball has been lifted and replaced, it is in play even if the ball-marker has not been removed.
Line of Play

The line where the player intends his or her ball to go after a stroke, including the area on that line that is a reasonable distance up above the ground and on either side of that line.

The line of play is not necessarily a straight line between two points (for example, it may be a curved line based on where the player intends the ball to go).

Moved

When a ball at rest has left its original spot and come to rest on any other spot, and this can be seen by the naked eye (whether or not anyone actually sees it do so).

This applies whether the ball has gone up, down or horizontally in any direction away from its original spot.

If the ball only wobbles (sometimes referred to as oscillating) and stays on or returns to its original spot, the ball has not moved.

 

Interpretation Moved/1 - When Ball Resting on Object Has Moved

For the purpose of deciding whether a ball must be replaced or whether a player gets a penalty, a ball is treated as having moved only if it has moved in relation to a specific part of the larger condition or object it is resting on, unless the entire object the ball is resting on has moved in relation to the ground.

An example of when a ball has not moved includes when:

  • A ball is resting in the fork of a tree branch and the tree branch moves, but the ball's spot in the branch does not change.

Examples of when a ball has moved include when:

  • A ball is resting in a stationary plastic cup and the cup itself moves in relation to the ground because it is being blown by the wind.
  • A ball is resting in or on a stationary motorized cart that starts to move.

Interpretation Moved/2 - Television Evidence Shows Ball at Rest Changed Position but by Amount Not Reasonably Discernible to Naked Eye

When determining whether or not a ball at rest has moved, a player must make that judgment based on all the information reasonably available to him or her at the time, so that he or she can determine whether the ball must be replaced under the Rules. When the player's ball has left its original position and come to rest in another place by an amount that was not reasonably discernible to the naked eye at the time, a player's determination that the ball has not moved is conclusive, even if that determination is later shown to be incorrect through the use of sophisticated technology.

On the other hand, if the Committee determines, based on all of the evidence it has available, that the ball changed its position by an amount that was reasonably discernible to the naked eye at the time, the ball will be determined to have moved even though no-one actually saw it move.

Relief Area

The area where a player must drop a ball when taking relief under a Rule. Each relief Rule requires the player to use a specific relief area whose size and location are based on these three factors:

  • Reference Point: The point from which the size of relief area is measured.
  • Size of Relief Area Measured from Reference Point: The relief area is either one or two club-lengths from the reference point, but with certain limits:
  • Limits on Location of Relief Area: The location of the relief area may be limited in one or more ways so that, for example:
    • It is only in certain defined areas of the course, such as only in the general area, or not in a bunker or a penalty area,
    • It is not nearer the hole than the reference point or must be outside a penalty area or a bunker from which relief is being taken, or
    • It is where there is no interference (as defined in the particular Rule) from the condition from which relief is being taken.

In using club-lengths to determine the size of a relief area, the player may measure directly across a ditch, hole or similar thing, and directly across or through an object (such as a tree, fence, wall, tunnel, drain or sprinkler head), but is not allowed to measure through ground that naturally slopes up and down.

See Committee Procedures, Section 2I (Committee may choose to allow or require the player to use a dropping zone as a relief area when taking certain relief).

Bunker

A specially prepared area of sand, which is often a hollow from which turf or soil was removed.

These are not part of a bunker:

  • A lip, wall or face at the edge of a prepared area and consisting of soil, grass, stacked turf or artificial materials,
  • Soil or any growing or attached natural object inside the edge of a prepared area (such as grass, bushes or trees),
  • Sand that has spilled over or is outside the edge of a prepared area, and
  • All other areas of sand on the course that are not inside the edge of a prepared area (such as deserts and other natural sand areas or areas sometimes referred to as waste areas).

Bunkers are one of the five defined areas of the course.

A Committee may define a prepared area of sand as part of the general area (which means it is not a bunker) or may define a non-prepared area of sand as a bunker.

When a bunker is being repaired and the Committee defines the entire bunker as ground under repair, it is treated as part of the general area (which means it is not a bunker).

The word “sand” as used in this Definition and Rule 12 includes any material similar to sand that is used as bunker material (such as crushed shells), as well as any soil that is mixed in with the sand.

General Area

The area of the course that covers all of the course except for the other four defined areas: (1) the teeing area the player must play from in starting the hole he or she is playing, (2) all penalty areas, (3) all bunkers, and (4) the putting green of the hole the player is playing.

The general area includes:

  • All teeing locations on the course other than the teeing area, and
  • All wrong greens.
Replace

To place a ball by setting it down and letting it go, with the intent for it to be in play.

If the player sets a ball down without intending it to be in play, the ball has not been replaced and is not in play (see Rule 14.4).

Whenever a Rule requires a ball to be replaced, the Rule identifies a specific spot where the ball must be replaced.

 

Interpretation Replace/1 - Ball May Not Be Replaced with a Club

For a ball to be replaced in a right way, it must be set down and let go. This means the player must use his or her hand to put the ball back in play on the spot it was lifted or moved from.

For example, if a player lifts his or her ball from the putting green and sets it aside, the player must not replace the ball by rolling it to the required spot with a club. If he or she does so, the ball is not replaced in the right way and the player gets one penalty stroke under Rule 14.2b(2) (How Ball Must Be Replaced) if the mistake is not corrected before the stroke is made.

Drop

To hold the ball and let go of it so that it falls through the air, with the intent for the ball to be in play.

If the player lets go of a ball without intending it to be in play, the ball has not been dropped and is not in play (see Rule 14.4).

Each relief Rule identifies a specific relief area where the ball must be dropped and come to rest.

In taking relief, the player must let go of the ball from a location at knee height so that the ball:

  • Falls straight down, without the player throwing, spinning or rolling it or using any other motion that might affect where the ball will come to rest, and
  • Does not touch any part of the player’s body or equipment before it hits the ground (see Rule 14.3b).
Stroke and Distance

The procedure and penalty when a player takes relief under Rules 17, 18 or 19 by playing a ball from where the previous stroke was made (see Rule 14.6).

The term stroke and distance means that the player both:

  • Gets one penalty stroke, and
  • Loses the benefit of any gain of distance towards the hole from the spot where the previous stroke was made.
Drop

To hold the ball and let go of it so that it falls through the air, with the intent for the ball to be in play.

If the player lets go of a ball without intending it to be in play, the ball has not been dropped and is not in play (see Rule 14.4).

Outside Influence

Any of these people or things that can affect what happens to a player’s ball or equipment or to the course:

  • Any person (including another player), except the player or his or her caddie or the player’s partner or opponent or any of their caddies,
  • Any animal, and
  • Any natural or artificial object or anything else (including another ball in motion), except for natural forces.

 

Interpretation Outside Influence/1 - Status of Air and Water When Artificially Propelled

Although wind and water are natural forces and not outside influences, artificially propelled air and water are outside influences.

Examples include:

  • If a ball at rest on the putting green has not been lifted and replaced and is moved by air from a greenside fan, the ball must be replaced (Rule 9.6 and Rule 14.2).
  • If a ball at rest is moved by water coming from an irrigation system, the ball must be replaced (Rule 9.6 and Rule 14.2).
Outside Influence

Any of these people or things that can affect what happens to a player’s ball or equipment or to the course:

  • Any person (including another player), except the player or his or her caddie or the player’s partner or opponent or any of their caddies,

  • If a ball at rest is moved by water coming from an irrigation system, the ball must be replaced (Rule 9.6 and Rule 14.2).
Movable Obstruction

An obstruction that can be moved with reasonable effort and without damaging the obstruction or the course.

If part of an immovable obstruction or integral object (such as a gate or door or part of an attached cable) meets these two standards, that part is treated as a movable obstruction.

But this does not apply if the movable part of an immovable obstruction or integral object is not meant to be moved (such as a loose stone that is part of a stone wall).

Even when an obstruction is movable, the Committee may define it to be an immovable obstruction.

 

Interpretation Movable Obstruction/1 - Abandoned Ball Is a Movable Obstruction

An abandoned ball is a movable obstruction.

If the player sets a ball down without intending it to be in play, the ball has not been replaced and is not in play (see Rule 14.4).

Whenever a Rule requires a ball to be replaced, the Rule identifies a specific spot where the ball must be replaced.

 

Interpretation Replace/1 - Ball May Not Be Replaced with a Club

For a ball to be replaced in a right way, it must be set down and let go. This means the player must use his or her hand to put the ball back in play on the spot it was lifted or moved from.

For example, if a player lifts his or her ball from the putting green and sets it aside, the player must not replace the ball by rolling it to the required spot with a club. If he or she does so, the ball is not replaced in the right way and the player gets one penalty stroke under Rule 14.2b(2) (How Ball Must Be Replaced) if the mistake is not corrected before the stroke is made.

Moved

When a ball at rest has left its original spot and come to rest on any other spot, and this can be seen by the naked eye (whether or not anyone actually sees it do so).

This applies whether the ball has gone up, down or horizontally in any direction away from its original spot.

If the ball only wobbles (sometimes referred to as oscillating) and stays on or returns to its original spot, the ball has not moved.

 

Interpretation Moved/1 - When Ball Resting on Object Has Moved

For the purpose of deciding whether a ball must be replaced or whether a player gets a penalty, a ball is treated as having moved only if it has moved in relation to a specific part of the larger condition or object it is resting on, unless the entire object the ball is resting on has moved in relation to the ground.

An example of when a ball has not moved includes when:

  • A ball is resting in the fork of a tree branch and the tree branch moves, but the ball's spot in the branch does not change.

Examples of when a ball has moved include when:

  • A ball is resting in a stationary plastic cup and the cup itself moves in relation to the ground because it is being blown by the wind.
  • A ball is resting in or on a stationary motorized cart that starts to move.

Interpretation Moved/2 - Television Evidence Shows Ball at Rest Changed Position but by Amount Not Reasonably Discernible to Naked Eye

When determining whether or not a ball at rest has moved, a player must make that judgment based on all the information reasonably available to him or her at the time, so that he or she can determine whether the ball must be replaced under the Rules. When the player's ball has left its original position and come to rest in another place by an amount that was not reasonably discernible to the naked eye at the time, a player's determination that the ball has not moved is conclusive, even if that determination is later shown to be incorrect through the use of sophisticated technology.

On the other hand, if the Committee determines, based on all of the evidence it has available, that the ball changed its position by an amount that was reasonably discernible to the naked eye at the time, the ball will be determined to have moved even though no-one actually saw it move.

Outside Influence

Any of these people or things that can affect what happens to a player’s ball or equipment or to the course:

  • Any person (including another player), except the player or his or her caddie or the player’s partner or opponent or any of their caddies,
  • Any animal, and
  • Any natural or artificial object or anything else (including another ball in motion), except for natural forces.

 

Interpretation Outside Influence/1 - Status of Air and Water When Artificially Propelled

Although wind and water are natural forces and not outside influences, artificially propelled air and water are outside influences.

Examples include:

  • If a ball at rest on the putting green has not been lifted and replaced and is moved by air from a greenside fan, the ball must be replaced (Rule 9.6 and Rule 14.2).
  • If a ball at rest is moved by water coming from an irrigation system, the ball must be replaced (Rule 9.6 and Rule 14.2).

Putting Green

The area on the hole the player is playing that:

  • Is specially prepared for putting, or
  • The Committee has defined as the putting green (such as when a temporary green is used).

The putting green for a hole contains the hole into which the player tries to play a ball. The putting green is one of the five defined areas of the course. The putting greens for all other holes (which the player is not playing at the time) are wrong greens and part of the general area.

The edge of a putting green is defined by where it can be seen that the specially prepared area starts (such as where the grass has been distinctly cut to show the edge), unless the Committee defines the edge in a different way (such as by using a line or dots).

If a double green is used for two different holes:

  • The entire prepared area containing both holes is treated as the putting green when playing each hole.

But the Committee may define an edge that divides the double green into two different putting greens, so that when a player is playing one of the holes, the part of the double green for the other hole is a wrong green.

But the Committee may define an edge that divides the double green into two different putting greens, so that when a player is playing one of the holes, the part of the double green for the other hole is a wrong green.

Bunker

A specially prepared area of sand, which is often a hollow from which turf or soil was removed.

These are not part of a bunker:

  • A lip, wall or face at the edge of a prepared area and consisting of soil, grass, stacked turf or artificial materials,
  • Soil or any growing or attached natural object inside the edge of a prepared area (such as grass, bushes or trees),
  • Sand that has spilled over or is outside the edge of a prepared area, and
  • All other areas of sand on the course that are not inside the edge of a prepared area (such as deserts and other natural sand areas or areas sometimes referred to as waste areas).

Bunkers are one of the five defined areas of the course.

A Committee may define a prepared area of sand as part of the general area (which means it is not a bunker) or may define a non-prepared area of sand as a bunker.

When a bunker is being repaired and the Committee defines the entire bunker as ground under repair, it is treated as part of the general area (which means it is not a bunker).

The word “sand” as used in this Definition and Rule 12 includes any material similar to sand that is used as bunker material (such as crushed shells), as well as any soil that is mixed in with the sand.

Penalty Area

An area from which relief with a one-stroke penalty is allowed if the player’s ball comes to rest there.

A penalty area is:

  • Any body of water on the course (whether or not marked by the Committee), including a sea, lake, pond, river, ditch, surface drainage ditch or other open watercourse (even if not containing water), and
  • Any other part of the course the Committee defines as a penalty area.

A penalty area is one of the five defined areas of the course.

There are two different types of penalty areas, distinguished by the colour used to mark them:

  • Yellow penalty areas (marked with yellow lines or yellow stakes) give the player two relief options (Rules 17.1d(1) and (2)).
  • Red penalty areas (marked with red lines or red stakes) give the player an extra lateral relief option (Rule 17.1d(3)), in addition to the two relief options available for yellow penalty areas.

If the colour of a penalty area has not been marked or indicated by the Committee, it is treated as a red penalty area.

The edge of a penalty area extends both up above the ground and down below the ground:

  • This means that all ground and anything else (such as any natural or artificial object) inside the edge is part of the penalty area, whether on, above or below the surface of the ground.
  • If an object is both inside and outside the edge (such as a bridge over the penalty area, or a tree rooted inside the edge with branches extending outside the edge or vice versa), only the part of the object that is inside the edge is part of the penalty area.

The edge of a penalty area should be defined by stakes, lines or physical features:

  • Stakes: When defined by stakes, the edge of the penalty area is defined by the line between the outside points of the stakes at ground level, and the stakes are inside the penalty area.
  • Lines: When defined by a painted line on the ground, the edge of the penalty area is the outside edge of the line, and the line itself is in the penalty area.
  • Physical Features: When defined by physical features (such as a beach or desert area or a retaining wall), the Committee should say how the edge of the penalty area is defined.

When the edge of a penalty area is defined by lines or by physical features, stakes may be used to show where the penalty area is, but they have no other meaning.

When the edge of a body of water is not defined by the Committee, the edge of that penalty area is defined by its natural boundaries (that is, where the ground slopes down to form the depression that can hold the water).

If an open watercourse usually does not contain water (such as a drainage ditch or run-off area that is dry except during a rainy season), the Committee may define that area as part of the general area (which means it is not a penalty area).

Putting Green

The area on the hole the player is playing that:

  • Is specially prepared for putting, or
  • The Committee has defined as the putting green (such as when a temporary green is used).

The putting green for a hole contains the hole into which the player tries to play a ball. The putting green is one of the five defined areas of the course. The putting greens for all other holes (which the player is not playing at the time) are wrong greens and part of the general area.

But the Committee may define an edge that divides the double green into two different putting greens, so that when a player is playing one of the holes, the part of the double green for the other hole is a wrong green.

Outside Influence

Any of these people or things that can affect what happens to a player’s ball or equipment or to the course:

  • Any person (including another player), except the player or his or her caddie or the player’s partner or opponent or any of their caddies,
  • Any animal, and
  • Any natural or artificial object or anything else (including another ball in motion), except for natural forces.

 

Interpretation Outside Influence/1 - Status of Air and Water When Artificially Propelled

Although wind and water are natural forces and not outside influences, artificially propelled air and water are outside influences.

Examples include:

  • If a ball at rest on the putting green has not been lifted and replaced and is moved by air from a greenside fan, the ball must be replaced (Rule 9.6 and Rule 14.2).
  • If a ball at rest is moved by water coming from an irrigation system, the ball must be replaced (Rule 9.6 and Rule 14.2).

But the Committee may define an edge that divides the double green into two different putting greens, so that when a player is playing one of the holes, the part of the double green for the other hole is a wrong green.

General Area

The area of the course that covers all of the course except for the other four defined areas: (1) the teeing area the player must play from in starting the hole he or she is playing, (2) all penalty areas, (3) all bunkers, and (4) the putting green of the hole the player is playing.

The general area includes:

  • All teeing locations on the course other than the teeing area, and
  • All wrong greens.
Bunker

A specially prepared area of sand, which is often a hollow from which turf or soil was removed.

These are not part of a bunker:

  • A lip, wall or face at the edge of a prepared area and consisting of soil, grass, stacked turf or artificial materials,
  • Soil or any growing or attached natural object inside the edge of a prepared area (such as grass, bushes or trees),
  • Sand that has spilled over or is outside the edge of a prepared area, and
  • All other areas of sand on the course that are not inside the edge of a prepared area (such as deserts and other natural sand areas or areas sometimes referred to as waste areas).

Bunkers are one of the five defined areas of the course.

A Committee may define a prepared area of sand as part of the general area (which means it is not a bunker) or may define a non-prepared area of sand as a bunker.

When a bunker is being repaired and the Committee defines the entire bunker as ground under repair, it is treated as part of the general area (which means it is not a bunker).

The word “sand” as used in this Definition and Rule 12 includes any material similar to sand that is used as bunker material (such as crushed shells), as well as any soil that is mixed in with the sand.

A penalty area is:

  • Any body of water on the course (whether or not marked by the Committee), including a sea, lake, pond, river, ditch, surface drainage ditch or other open watercourse (even if not containing water), and

Replace

To place a ball by setting it down and letting it go, with the intent for it to be in play.

If the player sets a ball down without intending it to be in play, the ball has not been replaced and is not in play (see Rule 14.4).

Whenever a Rule requires a ball to be replaced, the Rule identifies a specific spot where the ball must be replaced.

 

Interpretation Replace/1 - Ball May Not Be Replaced with a Club

For a ball to be replaced in a right way, it must be set down and let go. This means the player must use his or her hand to put the ball back in play on the spot it was lifted or moved from.

For example, if a player lifts his or her ball from the putting green and sets it aside, the player must not replace the ball by rolling it to the required spot with a club. If he or she does so, the ball is not replaced in the right way and the player gets one penalty stroke under Rule 14.2b(2) (How Ball Must Be Replaced) if the mistake is not corrected before the stroke is made.

Putting Green

The area on the hole the player is playing that:

  • Is specially prepared for putting, or
  • The Committee has defined as the putting green (such as when a temporary green is used).

The putting green for a hole contains the hole into which the player tries to play a ball. The putting green is one of the five defined areas of the course. The putting greens for all other holes (which the player is not playing at the time) are wrong greens and part of the general area.

An area from which relief with a one-stroke penalty is allowed if the player’s ball comes to rest there.

A penalty area is:

  • Any body of water on the course (whether or not marked by the Committee), including a sea, lake, pond, river, ditch, surface drainage ditch or other open watercourse (even if not containing water), and
  • Any other part of the course the Committee defines as a penalty area.

If an open watercourse usually does not contain water (such as a drainage ditch or run-off area that is dry except during a rainy season), the Committee may define that area as part of the general area (which means it is not a penalty area).

General Area

The area of the course that covers all of the course except for the other four defined areas: (1) the teeing area the player must play from in starting the hole he or she is playing, (2) all penalty areas, (3) all bunkers, and (4) the putting green of the hole the player is playing.

The general area includes:

  • All teeing locations on the course other than the teeing area, and
  • All wrong greens.
Known or Virtually Certain

The standard for deciding what happened to a player’s ball – for example, whether the ball came to rest in a penalty area, whether it moved or what caused it to move.

Known or virtually certain means more than just possible or probable. It means that either:

  • There is conclusive evidence that the event in question happened to the player's ball, such as when the player or other witnesses saw it happen, or
  • Although there is a very small degree of doubt, all reasonably available information shows that it is at least 95% likely that the event in question happened.

"All reasonably available information" includes all information the player knows and all other information he or she can get with reasonable effort and without unreasonable delay.

 

Interpretation Known or Virtually Certain/1 - Applying "Known or Virtually Certain" Standard When Ball Moves

When it is not "known" what caused the ball to move, all reasonably available information must be considered and the evidence must be evaluated to determine if it is "virtually certain" that the player, opponent or outside influence caused the ball to move.

Depending on the circumstances, reasonably available information may include, but is not limited to:

  • The effect of any actions taken near the ball (such as movement of loose impediments, practice swings, grounding club and taking a stance),
  • Time elapsed between such actions and the movement of the ball,
  • The lie of the ball before it moved (such as on a fairway, perched on longer grass, on a surface imperfection or on the putting green),
  • The conditions of the ground near the ball (such as the degree of slope or presence of surface irregularities, etc), and
  • Wind speed and direction, rain and other weather conditions.

Interpretation Known or Virtually Certain/2 - Virtual Certainty Is Irrelevant if It Comes to Light After Three-Minute Search Expires

Determining whether there is knowledge or virtual certainty must be based on evidence known to the player at the time the three-minute search time expires.

Examples of when the player's later findings are irrelevant include when:

  • A player's tee shot comes to rest in an area containing heavy rough and a large animal hole. After a three-minute search, it is determined that it is not known or virtually certain that the ball is in the animal hole. As the player returns to the teeing area, the ball is found in the animal hole.
  • Even though the player has not yet put another ball in play, the player must take stroke-and-distance relief for a lost ball (Rule 18.2b - What to Do When Ball is Lost or Out of Bounds) since it was not known or virtually certain that the ball was in the animal hole, when the search time expired.
  • A player cannot find his or her ball and believes it may have been picked up by a spectator (outside influence), but there is not enough evidence to be virtually certain of this. A short time after the three-minute search time expires, a spectator is found to have the player's ball.

The player must take stroke-and-distance relief for a lost ball (Rule 18.2b) since the movement by the outside influence only became known after the search time expired.

Interpretation Known or Virtually Certain/3 - Player Unaware Ball Played by Another Player

It must be known or virtually certain that a player's ball has been played by another player as a wrong ball to treat it as being moved.

For example, in stroke play, Player A and Player B hit their tee shots into the same general location. Player A finds a ball and plays it. Player B goes forward to look for his or her ball and cannot find it. After three minutes, Player B starts back to the tee to play another ball. On the way, Player B finds Player A's ball and knows then that Player A has played his or her ball in error.

Player A gets the general penalty for playing a wrong ball and must then play his or her own ball (Rule 6.3c). Player A's ball was not lost even though both players searched for more than three minutes because Player A did not start searching for his or her ball; the searching was for Player B's ball. Regarding Player B's ball, Player B's original ball was lost and he or she must put another ball in play under penalty of stroke and distance (Rule 18.2b), because it was not known or virtually certain when the three-minute search time expired that the ball had been played by another player.

When a ball at rest has left its original spot and come to rest on any other spot, and this can be seen by the naked eye (whether or not anyone actually sees it do so).

This applies whether the ball has gone up, down or horizontally in any direction away from its original spot.

If the ball only wobbles (sometimes referred to as oscillating) and stays on or returns to its original spot, the ball has not moved.

 

Interpretation Moved/1 - When Ball Resting on Object Has Moved

For the purpose of deciding whether a ball must be replaced or whether a player gets a penalty, a ball is treated as having moved only if it has moved in relation to a specific part of the larger condition or object it is resting on, unless the entire object the ball is resting on has moved in relation to the ground.

An example of when a ball has not moved includes when:

  • A ball is resting in the fork of a tree branch and the tree branch moves, but the ball's spot in the branch does not change.

Examples of when a ball has moved include when:

  • A ball is resting in a stationary plastic cup and the cup itself moves in relation to the ground because it is being blown by the wind.
  • A ball is resting in or on a stationary motorized cart that starts to move.

Interpretation Moved/2 - Television Evidence Shows Ball at Rest Changed Position but by Amount Not Reasonably Discernible to Naked Eye

When determining whether or not a ball at rest has moved, a player must make that judgment based on all the information reasonably available to him or her at the time, so that he or she can determine whether the ball must be replaced under the Rules. When the player's ball has left its original position and come to rest in another place by an amount that was not reasonably discernible to the naked eye at the time, a player's determination that the ball has not moved is conclusive, even if that determination is later shown to be incorrect through the use of sophisticated technology.

On the other hand, if the Committee determines, based on all of the evidence it has available, that the ball changed its position by an amount that was reasonably discernible to the naked eye at the time, the ball will be determined to have moved even though no-one actually saw it move.

Outside Influence

Any of these people or things that can affect what happens to a player’s ball or equipment or to the course:

  • Any person (including another player), except the player or his or her caddie or the player’s partner or opponent or any of their caddies,
  • Any animal, and
  • Any natural or artificial object or anything else (including another ball in motion), except for natural forces.

 

Interpretation Outside Influence/1 - Status of Air and Water When Artificially Propelled

Although wind and water are natural forces and not outside influences, artificially propelled air and water are outside influences.

Examples include:

  • If a ball at rest on the putting green has not been lifted and replaced and is moved by air from a greenside fan, the ball must be replaced (Rule 9.6 and Rule 14.2).
  • If a ball at rest is moved by water coming from an irrigation system, the ball must be replaced (Rule 9.6 and Rule 14.2).

Any of these people or things that can affect what happens to a player’s ball or equipment or to the course:

  • Any person (including another player), except the player or his or her caddie or the player’s partner or opponent or any of their caddies,
  • Any animal, and
  • Any natural or artificial object or anything else (including another ball in motion), except for natural forces.

 

Interpretation Outside Influence/1 - Status of Air and Water When Artificially Propelled

Although wind and water are natural forces and not outside influences, artificially propelled air and water are outside influences.

Examples include:

  • If a ball at rest on the putting green has not been lifted and replaced and is moved by air from a greenside fan, the ball must be replaced (Rule 9.6 and Rule 14.2).
  • If a ball at rest is moved by water coming from an irrigation system, the ball must be replaced (Rule 9.6 and Rule 14.2).
Wrong Place

Any place on the course other than where the player is required or allowed to play his or her ball under the Rules.

Examples of playing from a wrong place are:

  • Playing a ball after replacing it on the wrong spot or without replacing it when required by the Rules.
  • Playing a dropped ball from outside the required relief area.
  • Taking relief under a wrong Rule, so that the ball is dropped in and played from a place not allowed under the Rules.
  • Playing a ball from a no play zone or when a no play zone interferes with the player’s area of intended stance or swing.

Playing a ball from outside the teeing area in starting play of a hole or in trying to correct that mistake is not playing from a wrong place (see Rule 6.1b).

Stroke

The forward movement of the club made to strike the ball.

But a stroke has not been made if the player:

  • Decides during the downswing not to strike the ball and avoids doing so by deliberately stopping the clubhead before it reaches the ball or, if unable to stop, by deliberately missing the ball.
  • Accidentally strikes the ball when making a practice swing or while preparing to make a stroke.

When the Rules refer to "playing a ball," it means the same as making a stroke.

The player's score for a hole or a round is described as a number of "strokes" or "strokes taken," which means both all strokes made and any penalty strokes (see Rule 3.1c).

 

Interpretation Stroke/1 - Determining If a Stroke Was Made

If a player starts the downswing with a club intending to strike the ball, his or her action counts as a stroke when:

  • The clubhead is deflected or stopped by an outside influence (such as the branch of a tree) whether or not the ball is struck.
  • The clubhead separates from the shaft during the downswing and the player continues the downswing with the shaft alone, whether or not the ball is struck with the shaft.
  • The clubhead separates from the shaft during the downswing and the player continues the downswing with the shaft alone, with the clubhead falling and striking the ball.

The player's action does not count as a stroke in each of following situations:

  • During the downswing, a player's clubhead separates from the shaft. The player stops the downswing short of the ball, but the clubhead falls and strikes and moves the ball.
  • During the backswing, a player's clubhead separates from the shaft. The player completes the downswing with the shaft but does not strike the ball.
  • A ball is lodged in a tree branch beyond the reach of a club. If the player moves the ball by striking a lower part of the branch instead of the ball, Rule 9.4 (Ball Lifted or Moved by Player) applies.
Moved

When a ball at rest has left its original spot and come to rest on any other spot, and this can be seen by the naked eye (whether or not anyone actually sees it do so).

This applies whether the ball has gone up, down or horizontally in any direction away from its original spot.

If the ball only wobbles (sometimes referred to as oscillating) and stays on or returns to its original spot, the ball has not moved.

 

Interpretation Moved/1 - When Ball Resting on Object Has Moved

For the purpose of deciding whether a ball must be replaced or whether a player gets a penalty, a ball is treated as having moved only if it has moved in relation to a specific part of the larger condition or object it is resting on, unless the entire object the ball is resting on has moved in relation to the ground.

An example of when a ball has not moved includes when:

  • A ball is resting in the fork of a tree branch and the tree branch moves, but the ball's spot in the branch does not change.

Examples of when a ball has moved include when:

  • A ball is resting in a stationary plastic cup and the cup itself moves in relation to the ground because it is being blown by the wind.
  • A ball is resting in or on a stationary motorized cart that starts to move.

Interpretation Moved/2 - Television Evidence Shows Ball at Rest Changed Position but by Amount Not Reasonably Discernible to Naked Eye

When determining whether or not a ball at rest has moved, a player must make that judgment based on all the information reasonably available to him or her at the time, so that he or she can determine whether the ball must be replaced under the Rules. When the player's ball has left its original position and come to rest in another place by an amount that was not reasonably discernible to the naked eye at the time, a player's determination that the ball has not moved is conclusive, even if that determination is later shown to be incorrect through the use of sophisticated technology.

On the other hand, if the Committee determines, based on all of the evidence it has available, that the ball changed its position by an amount that was reasonably discernible to the naked eye at the time, the ball will be determined to have moved even though no-one actually saw it move.

Course

The entire area of play within the edge of any boundaries set by the Committee:

  • All areas inside the boundary edge are in bounds and part of the course.
  • All areas outside the boundary edge are out of bounds and not part of the course.
  • The boundary edge extends both up above the ground and down below the ground.

The course is made up of the five defined areas of the course.

Outside Influence

Any of these people or things that can affect what happens to a player’s ball or equipment or to the course:

  • Any person (including another player), except the player or his or her caddie or the player’s partner or opponent or any of their caddies,
  • Any animal, and
  • Any natural or artificial object or anything else (including another ball in motion), except for natural forces.

 

Interpretation Outside Influence/1 - Status of Air and Water When Artificially Propelled

Although wind and water are natural forces and not outside influences, artificially propelled air and water are outside influences.

Examples include:

  • If a ball at rest on the putting green has not been lifted and replaced and is moved by air from a greenside fan, the ball must be replaced (Rule 9.6 and Rule 14.2).
  • If a ball at rest is moved by water coming from an irrigation system, the ball must be replaced (Rule 9.6 and Rule 14.2).
Out of Bounds

All areas outside the boundary edge of the course as defined by the Committee. All areas inside that edge are in bounds.

The boundary edge of the course extends both up above the ground and down below the ground:

  • This means that all ground and anything else (such as any natural or artificial object) inside the boundary edge is in bounds, whether on, above or below the surface of the ground.
  • If an object is both inside and outside the boundary edge (such as steps attached to a boundary fence, or a tree rooted outside the edge with branches extending inside the edge or vice versa), only the part of the object that is outside the edge is out of bounds.

The boundary edge should be defined by boundary objects or lines:

  • Boundary objects: When defined by stakes or a fence, the boundary edge is defined by the line between the course-side points of the stakes or fence posts at ground level (excluding angled supports), and those stakes or fence posts are out of bounds.
    When defined by other objects such as a wall or when the Committee wishes to treat a boundary fence in a different way, the Committee should define the boundary edge.
  • Lines: When defined by a painted line on the ground, the boundary edge is the course-side edge of the line, and the line itself is out of bounds.
    When a line on the ground defines the boundary edge, stakes may be used to show where the boundary edge is, but they have no other meaning.

Boundary stakes or lines should be white.

Wrong Ball

Any ball other than the player’s:

  • Ball in play (whether the original ball or a substituted ball),
  • Provisional ball (before it is abandoned under Rule 18.3c), or
  • Second ball in stroke play played under Rules 14.7b or 20.1c.

Examples of a wrong ball are:

  • Another player’s ball in play.
  • A stray ball.
  • The player’s own ball that is out of bounds, has become lost or has been lifted and not yet put back in play.

 

Interpretation Wrong Ball/1 - Part of Wrong Ball Is Still Wrong Ball

If a player makes a stroke at part of a stray ball that he or she mistakenly thought was the ball in play, he or she has made a stroke at a wrong ball and Rule 6.3c applies.

Known or Virtually Certain

The standard for deciding what happened to a player’s ball – for example, whether the ball came to rest in a penalty area, whether it moved or what caused it to move.

Known or virtually certain means more than just possible or probable. It means that either:

  • There is conclusive evidence that the event in question happened to the player's ball, such as when the player or other witnesses saw it happen, or
  • Although there is a very small degree of doubt, all reasonably available information shows that it is at least 95% likely that the event in question happened.

"All reasonably available information" includes all information the player knows and all other information he or she can get with reasonable effort and without unreasonable delay.

 

Interpretation Known or Virtually Certain/1 - Applying "Known or Virtually Certain" Standard When Ball Moves

When it is not "known" what caused the ball to move, all reasonably available information must be considered and the evidence must be evaluated to determine if it is "virtually certain" that the player, opponent or outside influence caused the ball to move.

Depending on the circumstances, reasonably available information may include, but is not limited to:

  • The effect of any actions taken near the ball (such as movement of loose impediments, practice swings, grounding club and taking a stance),
  • Time elapsed between such actions and the movement of the ball,
  • The lie of the ball before it moved (such as on a fairway, perched on longer grass, on a surface imperfection or on the putting green),
  • The conditions of the ground near the ball (such as the degree of slope or presence of surface irregularities, etc), and
  • Wind speed and direction, rain and other weather conditions.

Interpretation Known or Virtually Certain/2 - Virtual Certainty Is Irrelevant if It Comes to Light After Three-Minute Search Expires

Determining whether there is knowledge or virtual certainty must be based on evidence known to the player at the time the three-minute search time expires.

Examples of when the player's later findings are irrelevant include when:

  • A player's tee shot comes to rest in an area containing heavy rough and a large animal hole. After a three-minute search, it is determined that it is not known or virtually certain that the ball is in the animal hole. As the player returns to the teeing area, the ball is found in the animal hole.
  • Even though the player has not yet put another ball in play, the player must take stroke-and-distance relief for a lost ball (Rule 18.2b - What to Do When Ball is Lost or Out of Bounds) since it was not known or virtually certain that the ball was in the animal hole, when the search time expired.
  • A player cannot find his or her ball and believes it may have been picked up by a spectator (outside influence), but there is not enough evidence to be virtually certain of this. A short time after the three-minute search time expires, a spectator is found to have the player's ball.

The player must take stroke-and-distance relief for a lost ball (Rule 18.2b) since the movement by the outside influence only became known after the search time expired.

Interpretation Known or Virtually Certain/3 - Player Unaware Ball Played by Another Player

It must be known or virtually certain that a player's ball has been played by another player as a wrong ball to treat it as being moved.

For example, in stroke play, Player A and Player B hit their tee shots into the same general location. Player A finds a ball and plays it. Player B goes forward to look for his or her ball and cannot find it. After three minutes, Player B starts back to the tee to play another ball. On the way, Player B finds Player A's ball and knows then that Player A has played his or her ball in error.

Player A gets the general penalty for playing a wrong ball and must then play his or her own ball (Rule 6.3c). Player A's ball was not lost even though both players searched for more than three minutes because Player A did not start searching for his or her ball; the searching was for Player B's ball. Regarding Player B's ball, Player B's original ball was lost and he or she must put another ball in play under penalty of stroke and distance (Rule 18.2b), because it was not known or virtually certain when the three-minute search time expired that the ball had been played by another player.

Wrong Ball

Any ball other than the player’s:

  • Ball in play (whether the original ball or a substituted ball),
  • Provisional ball (before it is abandoned under Rule 18.3c), or
  • Second ball in stroke play played under Rules 14.7b or 20.1c.

Examples of a wrong ball are:

  • Another player’s ball in play.
  • A stray ball.
  • The player’s own ball that is out of bounds, has become lost or has been lifted and not yet put back in play.

 

Interpretation Wrong Ball/1 - Part of Wrong Ball Is Still Wrong Ball

If a player makes a stroke at part of a stray ball that he or she mistakenly thought was the ball in play, he or she has made a stroke at a wrong ball and Rule 6.3c applies.

Match Play

A form of play where a player or side plays directly against an opponent or opposing side in a head-to-head match of one or more rounds:

  • A player or side wins a hole in the match by completing the hole in fewer strokes (including strokes made and penalty strokes), and
  • The match is won when a player or side leads the opponent or opposing side by more holes than remain to be played.

Match play can be played as a singles match (where one player plays directly against one opponent), a Three-Ball match or a Foursomes or Four-Ball match between sides of two partners.

Moved

When a ball at rest has left its original spot and come to rest on any other spot, and this can be seen by the naked eye (whether or not anyone actually sees it do so).

This applies whether the ball has gone up, down or horizontally in any direction away from its original spot.

If the ball only wobbles (sometimes referred to as oscillating) and stays on or returns to its original spot, the ball has not moved.

 

Interpretation Moved/1 - When Ball Resting on Object Has Moved

For the purpose of deciding whether a ball must be replaced or whether a player gets a penalty, a ball is treated as having moved only if it has moved in relation to a specific part of the larger condition or object it is resting on, unless the entire object the ball is resting on has moved in relation to the ground.

An example of when a ball has not moved includes when:

  • A ball is resting in the fork of a tree branch and the tree branch moves, but the ball's spot in the branch does not change.

Examples of when a ball has moved include when:

  • A ball is resting in a stationary plastic cup and the cup itself moves in relation to the ground because it is being blown by the wind.
  • A ball is resting in or on a stationary motorized cart that starts to move.

Interpretation Moved/2 - Television Evidence Shows Ball at Rest Changed Position but by Amount Not Reasonably Discernible to Naked Eye

When determining whether or not a ball at rest has moved, a player must make that judgment based on all the information reasonably available to him or her at the time, so that he or she can determine whether the ball must be replaced under the Rules. When the player's ball has left its original position and come to rest in another place by an amount that was not reasonably discernible to the naked eye at the time, a player's determination that the ball has not moved is conclusive, even if that determination is later shown to be incorrect through the use of sophisticated technology.

On the other hand, if the Committee determines, based on all of the evidence it has available, that the ball changed its position by an amount that was reasonably discernible to the naked eye at the time, the ball will be determined to have moved even though no-one actually saw it move.

Course

The entire area of play within the edge of any boundaries set by the Committee:

  • All areas inside the boundary edge are in bounds and part of the course.
  • All areas outside the boundary edge are out of bounds and not part of the course.
  • The boundary edge extends both up above the ground and down below the ground.

The course is made up of the five defined areas of the course.

Outside Influence

Any of these people or things that can affect what happens to a player’s ball or equipment or to the course:

  • Any person (including another player), except the player or his or her caddie or the player’s partner or opponent or any of their caddies,
  • Any animal, and
  • Any natural or artificial object or anything else (including another ball in motion), except for natural forces.

 

Interpretation Outside Influence/1 - Status of Air and Water When Artificially Propelled

Although wind and water are natural forces and not outside influences, artificially propelled air and water are outside influences.

Examples include:

  • If a ball at rest on the putting green has not been lifted and replaced and is moved by air from a greenside fan, the ball must be replaced (Rule 9.6 and Rule 14.2).
  • If a ball at rest is moved by water coming from an irrigation system, the ball must be replaced (Rule 9.6 and Rule 14.2).
Opponent

The person a player competes against in a match. The term opponent applies only in match play.

Stroke

The forward movement of the club made to strike the ball.

But a stroke has not been made if the player:

  • Decides during the downswing not to strike the ball and avoids doing so by deliberately stopping the clubhead before it reaches the ball or, if unable to stop, by deliberately missing the ball.
  • Accidentally strikes the ball when making a practice swing or while preparing to make a stroke.

When the Rules refer to "playing a ball," it means the same as making a stroke.

The player's score for a hole or a round is described as a number of "strokes" or "strokes taken," which means both all strokes made and any penalty strokes (see Rule 3.1c).

 

Interpretation Stroke/1 - Determining If a Stroke Was Made

If a player starts the downswing with a club intending to strike the ball, his or her action counts as a stroke when:

  • The clubhead is deflected or stopped by an outside influence (such as the branch of a tree) whether or not the ball is struck.
  • The clubhead separates from the shaft during the downswing and the player continues the downswing with the shaft alone, whether or not the ball is struck with the shaft.
  • The clubhead separates from the shaft during the downswing and the player continues the downswing with the shaft alone, with the clubhead falling and striking the ball.

The player's action does not count as a stroke in each of following situations:

  • During the downswing, a player's clubhead separates from the shaft. The player stops the downswing short of the ball, but the clubhead falls and strikes and moves the ball.
  • During the backswing, a player's clubhead separates from the shaft. The player completes the downswing with the shaft but does not strike the ball.
  • A ball is lodged in a tree branch beyond the reach of a club. If the player moves the ball by striking a lower part of the branch instead of the ball, Rule 9.4 (Ball Lifted or Moved by Player) applies.
Opponent

The person a player competes against in a match. The term opponent applies only in match play.

  • The clubhead separates from the shaft during the downswing and the player continues the downswing with the shaft alone, whether or not the ball is struck with the shaft.
  • The clubhead separates from the shaft during the downswing and the player continues the downswing with the shaft alone, with the clubhead falling and striking the ball.

The player's action does not count as a stroke in each of following situations:

  • During the downswing, a player's clubhead separates from the shaft. The player stops the downswing short of the ball, but the clubhead falls and strikes and moves the ball.
  • During the backswing, a player's clubhead separates from the shaft. The player completes the downswing with the shaft but does not strike the ball.
  • A ball is lodged in a tree branch beyond the reach of a club. If the player moves the ball by striking a lower part of the branch instead of the ball, Rule 9.4 (Ball Lifted or Moved by Player) applies.
Wrong Ball

Any ball other than the player’s:

  • Ball in play (whether the original ball or a substituted ball),
  • Provisional ball (before it is abandoned under Rule 18.3c), or
  • Second ball in stroke play played under Rules 14.7b or 20.1c.

Examples of a wrong ball are:

  • Another player’s ball in play.
  • A stray ball.
  • The player’s own ball that is out of bounds, has become lost or has been lifted and not yet put back in play.

 

Interpretation Wrong Ball/1 - Part of Wrong Ball Is Still Wrong Ball

If a player makes a stroke at part of a stray ball that he or she mistakenly thought was the ball in play, he or she has made a stroke at a wrong ball and Rule 6.3c applies.

Stroke Play

A form of play where a player or side competes against all other players or sides in the competition.

In the regular form of stroke play (see Rule 3.3):

  • A player’s or side’s score for a round is the total number of strokes (including strokes made and any penalty strokes) to hole out on each hole, and
  • The winner is the player or side who completes all rounds in the fewest total strokes.

Other forms of stroke play with different scoring methods are Stableford, Maximum Score and Par/Bogey (see Rule 21).

All forms of stroke play  can be played either in individual competitions (each player competing on his or her own) or in competitions involving sides of partners (Foursomes or Four-Ball).

Moved

When a ball at rest has left its original spot and come to rest on any other spot, and this can be seen by the naked eye (whether or not anyone actually sees it do so).

This applies whether the ball has gone up, down or horizontally in any direction away from its original spot.

If the ball only wobbles (sometimes referred to as oscillating) and stays on or returns to its original spot, the ball has not moved.

 

Interpretation Moved/1 - When Ball Resting on Object Has Moved

For the purpose of deciding whether a ball must be replaced or whether a player gets a penalty, a ball is treated as having moved only if it has moved in relation to a specific part of the larger condition or object it is resting on, unless the entire object the ball is resting on has moved in relation to the ground.

An example of when a ball has not moved includes when:

  • A ball is resting in the fork of a tree branch and the tree branch moves, but the ball's spot in the branch does not change.

Examples of when a ball has moved include when:

  • A ball is resting in a stationary plastic cup and the cup itself moves in relation to the ground because it is being blown by the wind.
  • A ball is resting in or on a stationary motorized cart that starts to move.

Interpretation Moved/2 - Television Evidence Shows Ball at Rest Changed Position but by Amount Not Reasonably Discernible to Naked Eye

When determining whether or not a ball at rest has moved, a player must make that judgment based on all the information reasonably available to him or her at the time, so that he or she can determine whether the ball must be replaced under the Rules. When the player's ball has left its original position and come to rest in another place by an amount that was not reasonably discernible to the naked eye at the time, a player's determination that the ball has not moved is conclusive, even if that determination is later shown to be incorrect through the use of sophisticated technology.

On the other hand, if the Committee determines, based on all of the evidence it has available, that the ball changed its position by an amount that was reasonably discernible to the naked eye at the time, the ball will be determined to have moved even though no-one actually saw it move.

Course

The entire area of play within the edge of any boundaries set by the Committee:

  • All areas inside the boundary edge are in bounds and part of the course.
  • All areas outside the boundary edge are out of bounds and not part of the course.
  • The boundary edge extends both up above the ground and down below the ground.

The course is made up of the five defined areas of the course.

Outside Influence

Any of these people or things that can affect what happens to a player’s ball or equipment or to the course:

  • Any person (including another player), except the player or his or her caddie or the player’s partner or opponent or any of their caddies,
  • Any animal, and
  • Any natural or artificial object or anything else (including another ball in motion), except for natural forces.

 

Interpretation Outside Influence/1 - Status of Air and Water When Artificially Propelled

Although wind and water are natural forces and not outside influences, artificially propelled air and water are outside influences.

Examples include:

  • If a ball at rest on the putting green has not been lifted and replaced and is moved by air from a greenside fan, the ball must be replaced (Rule 9.6 and Rule 14.2).
  • If a ball at rest is moved by water coming from an irrigation system, the ball must be replaced (Rule 9.6 and Rule 14.2).
Stroke

The forward movement of the club made to strike the ball.

But a stroke has not been made if the player:

  • Decides during the downswing not to strike the ball and avoids doing so by deliberately stopping the clubhead before it reaches the ball or, if unable to stop, by deliberately missing the ball.
  • Accidentally strikes the ball when making a practice swing or while preparing to make a stroke.

  • The clubhead separates from the shaft during the downswing and the player continues the downswing with the shaft alone, with the clubhead falling and striking the ball.

The player's action does not count as a stroke in each of following situations:

  • During the downswing, a player's clubhead separates from the shaft. The player stops the downswing short of the ball, but the clubhead falls and strikes and moves the ball.
  • During the backswing, a player's clubhead separates from the shaft. The player completes the downswing with the shaft but does not strike the ball.
  • A ball is lodged in a tree branch beyond the reach of a club. If the player moves the ball by striking a lower part of the branch instead of the ball, Rule 9.4 (Ball Lifted or Moved by Player) applies.
Round

18 or fewer holes played in the order set by the Committee.

Scorecard

The document where a player’s score for each hole is entered in stroke play.

The scorecard may be in any paper or electronic form approved by the Committee that allows:

  • The player’s score to be entered for each hole,
  • The player’s handicap to be entered, if it is a handicap competition, and
  • The marker and the player to certify the scores, and the player to certify his or her handicap in a handicap competition, either by physical signature or by a method of electronic certification approved by the Committee.

A scorecard is not required in match play but may be used by the players to help keep the match score.

Stroke

The forward movement of the club made to strike the ball.

But a stroke has not been made if the player:

  • Decides during the downswing not to strike the ball and avoids doing so by deliberately stopping the clubhead before it reaches the ball or, if unable to stop, by deliberately missing the ball.
  • Accidentally strikes the ball when making a practice swing or while preparing to make a stroke.

When the Rules refer to "playing a ball," it means the same as making a stroke.

The player's score for a hole or a round is described as a number of "strokes" or "strokes taken," which means both all strokes made and any penalty strokes (see Rule 3.1c).

 

Interpretation Stroke/1 - Determining If a Stroke Was Made

If a player starts the downswing with a club intending to strike the ball, his or her action counts as a stroke when:

  • The clubhead is deflected or stopped by an outside influence (such as the branch of a tree) whether or not the ball is struck.
  • The clubhead separates from the shaft during the downswing and the player continues the downswing with the shaft alone, whether or not the ball is struck with the shaft.
  • The clubhead separates from the shaft during the downswing and the player continues the downswing with the shaft alone, with the clubhead falling and striking the ball.

The player's action does not count as a stroke in each of following situations:

  • During the downswing, a player's clubhead separates from the shaft. The player stops the downswing short of the ball, but the clubhead falls and strikes and moves the ball.
  • During the backswing, a player's clubhead separates from the shaft. The player completes the downswing with the shaft but does not strike the ball.
  • A ball is lodged in a tree branch beyond the reach of a club. If the player moves the ball by striking a lower part of the branch instead of the ball, Rule 9.4 (Ball Lifted or Moved by Player) applies.

A scorecard is not required in match play but may be used by the players to help keep the match score.

Wrong Ball

Any ball other than the player’s:

  • Ball in play (whether the original ball or a substituted ball),
  • Provisional ball (before it is abandoned under Rule 18.3c), or
  • Second ball in stroke play played under Rules 14.7b or 20.1c.

Examples of a wrong ball are:

  • Another player’s ball in play.
  • A stray ball.
  • The player’s own ball that is out of bounds, has become lost or has been lifted and not yet put back in play.

 

Interpretation Wrong Ball/1 - Part of Wrong Ball Is Still Wrong Ball

If a player makes a stroke at part of a stray ball that he or she mistakenly thought was the ball in play, he or she has made a stroke at a wrong ball and Rule 6.3c applies.
