Rule 8
Rule 10

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).
9
Ball Played as It Lies; Ball at Rest Lifted or Moved

Rule 9 applies to a ball in play at rest on the course, and applies both during a round and while play is stopped under Rule 5.7a.

9.1
Ball Played as It Lies
a
Playing Ball from Where It Came to Rest

A player’s ball at rest on the course must be played as it lies, except when the Rules require or allow the player:

  • To play a ball from another place on the course, or
  • To lift a ball and then replace it on its original spot.
b
What to Do When Ball Moves During Backswing or Stroke

If a player’s ball at rest begins moving after the player has begun the stroke or the backswing for a stroke and the player goes on to make the stroke:

  • The ball must not be replaced, no matter what caused it to move.
  • Instead, the player must play the ball from where it comes to rest after the stroke.
  • If the player caused the ball to move, see Rule 9.4b to find out if there is a penalty.

Penalty for Playing Incorrectly Substituted Ball or Playing Ball from a Wrong Place in Breach of Rule 9.1: General Penalty under Rule 6.3b or 14.7a.

If multiple Rule breaches result from a single act or related acts, see Rule 1.3c(4).

9.2
Deciding Whether Ball Moved and What Caused It to Move
a
Deciding Whether Ball Moved

A player’s ball at rest is treated as having moved only if it is known or virtually certain that it did.

If the ball might have moved but this is not known or virtually certain, it is treated as not having moved and must be played as it lies.

b
Deciding What Caused Ball to Move

When a player’s ball at rest has moved:

  • It must be decided what caused it to move.
  • This determines whether the player must replace the ball or play it as it lies and whether there is a penalty.

(1) Four Possible Causes. The Rules recognize only four possible causes for a ball at rest that moves before the player makes a stroke:

  • Natural forces, such as wind or water (see Rule 9.3),
  • The player, including the player’s caddie (see Rule 9.4),
  • The opponent in match play, including the opponent's caddie (see Rule 9.5), or
  • An outside influence, including any other player in stroke play (see Rule 9.6).

See Rules 22.2 (in Foursomes, either partner may act for the side and action by the partner is treated as action of the player); 23.5 (in Four-Ball, either partner may act for the side and action by the partner concerning the player’s ball or equipment is treated as action of the player).

(2) “Known or Virtually Certain” Standard for Deciding What Caused Ball to Move.

  • The player, the opponent or an outside influence is treated as having caused the ball to move only if it is known or virtually certain to be the cause.
  • If it is not known or virtually certain that at least one of these was the cause, the ball is treated as having been moved by natural forces.

In applying this standard, all reasonably available information must be considered, which means all information the player knows or can get with reasonable effort and without unreasonably delaying play.

9.3
Ball Moved by Natural Forces

If natural forces (such as wind or water) cause a player’s ball at rest to move:

  • There is no penalty, and
  • The ball must be played from its new spot.

Exception – Ball on Putting Green Must Be Replaced If It Moves After Having Already Been Lifted and Replaced (see Rule 13.1d): If the player’s ball on the putting green moves after the player had already lifted and replaced the ball on the spot from which it moved:

  • The ball must be replaced on its original spot (which if not known must be estimated) (see Rule 14.2).
  • This is true no matter what caused it to move (including natural forces).

Penalty for Playing Incorrectly Substituted Ball or Playing Ball from a Wrong Place in Breach of Rule 9.3: General Penalty under Rule 6.3b or 14.7a.

If multiple Rule breaches result from a single act or related acts, see Rule 1.3c(4).

9.4
Ball Lifted or Moved by Player

This Rule applies only when it is known or virtually certain that a player (including the player’s caddie) lifted his or her ball at rest or caused it to move.

a
When Lifted or Moved Ball Must Be Replaced

If the player lifts his or her ball at rest or causes it to move, the ball must be replaced on its original spot (which if not known must be estimated) (see Rule 14.2), except:

  • When the player lifts the ball under a Rule to take relief or to replace the ball on a different spot (see Rules 14.2d and 14.2e), or
  • When the ball moves only after the player has begun the stroke or the backswing for a stroke and then goes on to make the stroke (see Rule 9.1b).
b
Penalty for Lifting or Deliberately Touching Ball or Causing It to Move

If the player lifts or deliberately touches his or her ball at rest or causes it to move, the player gets one penalty stroke.

But there are four exceptions:

Exception 1 – Player Allowed to Lift or Move Ball: There is no penalty when the player lifts the ball or causes it to move under a Rule that:

  • Allows the ball to be lifted and then replaced on its original spot,
  • Requires a moved ball to be replaced on its original spot, or
  • Requires or allows the player to drop or place a ball again or to play a ball from a different place.

Exception 2 – Accidental Movement Before Ball Is Found: There is no penalty when the player accidentally causes the ball to move while trying to find or identify it (see Rule 7.4).

Exception 3 – Accidental Movement on Putting Green: There is no penalty when the player accidentally causes the ball to move on the putting green (see Rule 13.1d), no matter how that happens.

Exception 4 – Accidental Movement Anywhere Except on Putting Green While Applying Rule: There is no penalty when the player accidentally causes the ball to move anywhere except on the putting green while taking reasonable actions to:

  • Mark the spot of the ball or lift or replace the ball, when allowed to do so (see Rules 14.1 and 14.2),
  • Remove a movable obstruction (see Rule 15.2),
  • Restore worsened conditions, when allowed to do so (see Rule 8.1d),
  • Take relief under a Rule, including in determining whether relief is available under a Rule (such as swinging a club to see if there is interference from a condition), or where to take relief (such as determining the nearest point of complete relief), or
  • Measure under a Rule (such as to decide the order of play under Rule 6.4).

Penalty for Playing Incorrectly Substituted Ball or Playing Ball from a Wrong Place in Breach of Rule 9.4: General Penalty under Rule 6.3b or 14.7a.

If multiple Rule breaches result from a single act or related acts, see Rule 1.3c(4).

9.5
Ball Lifted or Moved by Opponent in Match Play

This Rule applies only when it is known or virtually certain that the opponent (including the opponent's caddie) lifted a player’s ball at rest or caused it to move.

If the opponent plays the player’s ball as a wrong ball, that is covered by Rule 6.3c(1), not by this Rule.

a
When Lifted or Moved Ball Must Be Replaced

If the opponent lifts or moves the player’s ball at rest, the ball must be replaced on its original spot (which if not known must be estimated) (see Rule 14.2), except:

  • When the opponent is conceding the next stroke, a hole or the match (see Rule 3.2b), or
  • When the opponent lifts or moves the ball at the player’s request because the player intends to apply a Rule to take relief or to replace the ball on a different spot.
b
Penalty for Lifting or Deliberately Touching Ball or Causing It to Move

If the opponent lifts or deliberately touches the player’s ball at rest or causes it to move, the opponent gets one penalty stroke.

But there are several exceptions:

Exception 1 – Opponent Allowed to Lift Player’s Ball: There is no penalty when the opponent lifts the ball:

  • When conceding a stroke, a hole or the match to the player, or
  • At the player’s request.

Exception 2 – Marking and Lifting Player’s Ball on Putting Green by Mistake: There is no penalty when the opponent marks the spot of the player’s ball and lifts it on the putting green in the mistaken belief that it is the opponent's own ball.

Exception 3 – Same Exceptions as for the Player: There is no penalty when the opponent accidentally causes the ball to move while taking any of the actions covered by Exceptions 2, 3 or 4 in Rule 9.4b.

Penalty for Playing Incorrectly Substituted Ball or Playing Ball from a Wrong Place in Breach of Rule 9.5: General Penalty under Rule 6.3b or 14.7a.

If multiple Rule breaches result from a single act or related acts, see Rule 1.3c(4).

9.6
Ball Lifted or Moved by Outside Influence

If it is known or virtually certain that an outside influence (including another player in stroke play or another ball) lifted or moved a player’s ball:

  • There is no penalty, and
  • The ball must be replaced on its original spot (which if not known must be estimated) (see Rule 14.2).

This applies whether or not the player’s ball has been found.

But if it is not known or virtually certain that the ball was lifted or moved by an outside influence and the ball is lost, the player must take stroke-and-distance relief under Rule 18.2.

If the player’s ball is played as a wrong ball by another player, that is covered by Rule 6.3c(2), not by this Rule.

Penalty for Playing Incorrectly Substituted Ball or Playing Ball from a Wrong Place in Breach of Rule 9.6: General Penalty under Rule 6.3b or 14.7a.

If multiple Rule breaches result from a single act or related acts, see Rule 1.3c(4).

9.7
Ball-Marker Lifted or Moved

This Rule covers what to do if a ball-marker that is marking the spot of a lifted ball is lifted or moved before the ball is replaced.

a
Ball or Ball-Marker Must Be Replaced

If a player’s ball-marker is lifted or moved in any way (including by natural forces) before the ball is replaced, the player must either:

  • Replace the ball on its original spot (which if not known must be estimated) (see Rule 14.2), or
  • Place a ball-marker to mark that original spot.
b
Penalty for Lifting Ball-Marker or Causing It to Move

If the player, or his or her opponent in match play, lifts the player’s ball-marker or causes it to move (when the ball is lifted and not yet replaced),the player or opponent gets one penalty stroke.

Exception – Rule 9.4b and 9.5b Exceptions Apply to Lifting Ball-Marker or Causing It to Move: In all cases where the player or opponent gets no penalty for lifting the player’s ball or accidentally causing it to move, there is also no penalty for lifting or accidentally moving the player’s ball-marker.

Penalty for Playing Incorrectly Substituted Ball or Playing Ball from a Wrong Place in Breach of Rule 9.7: General Penalty under Rule 6.3b or 14.7a.

If multiple Rule breaches result from a single act or related acts, see Rule 1.3c(4).

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.

Round

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

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.

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.

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.

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.

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.

  • 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.
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.

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.

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.

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.

Substitute

To change the ball the player is using to play a hole by having another ball become the ball in play.

The player has substituted another ball when he or she puts that ball in play in any way (see Rule 14.4) instead of the player’s original ball, whether the original ball was:

  • In play, or
  • No longer in play because it had been lifted from the course or was lost or out of bounds.

A substituted ball is the player’s ball in play even if:

  • It was replaced, dropped or placed in a wrong way or wrong place, or
  • The player was required under the Rules to put the original ball back in play rather than to substitute another ball.
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).

General Penalty

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

 

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.

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.

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.

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.

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.

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.
Natural Forces

The effects of nature such as wind, water or when something happens for no apparent reason because of the effects of gravity.

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).

Opponent

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

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.

Opponent

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

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).

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 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).

Foursomes (also known as "Alternate Shot")

A form of play where two partners compete as a side by playing one ball in alternating order on each hole.

Foursomes may be played as a match-play competition between one side of two partners and another side of two partners or a stroke-play competition among multiple sides of two partners.

Partner

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

Side

Two or more partners competing as a single unit in a round in match play or stroke play.

Each set of partners is a side, whether each partner plays his or her own ball (Four-Ball) or the partners play one ball (Foursomes).

A side is not the same as a team. In a team competition, each team consists of players competing as individuals or as sides.

Partner

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

Four-Ball

A form of play where sides of two partners compete, with each player playing his or her own ball. A side’s score for a hole is the lower score of the two partners on that hole.

Four-Ball may be played as a match-play competition between one side of two partners and another side of two partners or a stroke-play competition among multiple sides of two partners.

Partner

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

Side

Two or more partners competing as a single unit in a round in match play or stroke play.

Each set of partners is a side, whether each partner plays his or her own ball (Four-Ball) or the partners play one ball (Foursomes).

A side is not the same as a team. In a team competition, each team consists of players competing as individuals or as sides.

Partner

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

Equipment

Anything used, worn, held or carried by the player or the player’s caddie.

Objects used for the care of the course, such as rakes, are equipment only while they are being held or carried by the player or caddie.

 

Interpretation Equipment/1 - Status of Items Carried by Someone Else for the Player

Items, other than clubs, that are carried by someone other than a player or his or her caddie are outside influences, even if they belong to the player. However, they are the player's equipment when in the player's or his or her caddie's possession.

For example, if a player asks a spectator to carry his or her umbrella, the umbrella is an outside influence while in the spectator's possession. However, if the spectator hands the umbrella to the player, it is now his or her equipment.

Opponent

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

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).
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.

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.

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.

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.

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.

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).

The effects of nature such as wind, water or when something happens for no apparent reason because of the effects of gravity.

Substitute

To change the ball the player is using to play a hole by having another ball become the ball in play.

The player has substituted another ball when he or she puts that ball in play in any way (see Rule 14.4) instead of the player’s original ball, whether the original ball was:

  • In play, or
  • No longer in play because it had been lifted from the course or was lost or out of bounds.

A substituted ball is the player’s ball in play even if:

  • It was replaced, dropped or placed in a wrong way or wrong place, or
  • The player was required under the Rules to put the original ball back in play rather than to substitute another ball.
General Penalty

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

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

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

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.

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).

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.
Stroke

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

But a stroke has not been made if the 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.

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.

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.

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.

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.

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).
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.

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.

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.

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.

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.

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.

Nearest Point of Complete Relief

The reference point for taking free relief from an abnormal course condition (Rule 16.1), dangerous animal condition (Rule 16.2), wrong green (Rule 13.1f) or no play zone (Rules 16.1f and 17.1e), or in taking relief under certain Local Rules.

It is the estimated point where the ball would lie that is:

  • Nearest to the ball’s original spot, but not nearer the hole than that spot,
  • In the required area of the course, and
  • Where the condition does not interfere with the stroke the player would have made from the original spot if the condition was not there.

Estimating this reference point requires the player to identify the choice of club, stance, swing and line of play he or she would have used for that stroke.

The player does not need to simulate that stroke by taking an actual stance and swinging with the chosen club (but it is recommended that the player normally do this to help in making an accurate estimate).

The nearest point of complete relief relates solely to the particular condition from which relief is being taken and may be in a location where there is interference by something else:

  • If the player takes relief and then has interference by another condition from which relief is allowed, the player may take relief again by determining a new nearest point of complete relief from the new condition.
  • Relief must be taken separately for each condition, except that the player may take relief from both conditions at the same time (based on determining the nearest point of complete relief from both) when, having already taken relief separately from each condition, it becomes reasonable to conclude that continuing to do so will result in continued interference by one or the other.

 

Interpretation Nearest Point of Complete Relief/1 - Diagrams Illustrating Nearest Point of Complete Relief

In the diagrams, the term "nearest point of complete relief" in Rule 16.1 (Abnormal Course Conditions) for relief from interference by ground under repair is illustrated in the case of both a right-handed and a left-handed player.

The nearest point of complete relief must be strictly interpreted. A player is not allowed to choose on which side of the ground under repair the ball will be dropped, unless there are two equidistant nearest points of complete relief. Even if one side of the ground under repair is fairway and the other is bushes, if the nearest point of complete relief is in the bushes, then that is the player's nearest point of complete relief.

Interpretation Nearest Point of Complete Relief/2 – Player Does Not Follow Recommended Procedure in Determining Nearest Point of Complete Relief

Although there is a recommended procedure for determining the nearest point of complete relief, the Rules do not require a player to determine this point when taking relief under a relevant Rule (such as when taking relief from an abnormal course condition under Rule 16.1b (Relief for Ball in General Area)). If a player does not determine a nearest point of complete relief accurately or identifies an incorrect nearest point of complete relief, the player only gets a penalty if this results in him or her dropping a ball into a relief area that does not satisfy the requirements of the Rule and the ball is then played.

Interpretation Nearest Point of Complete Relief/3 – Whether Player Has Taken Relief Incorrectly If Condition Still Interferes for Stroke with Club Not Used to Determine Nearest Point of Complete Relief

When a player is taking relief from an abnormal course condition, he or she is taking relief only for interference that he or she had with the club, stance, swing and line of play that would have been used to play the ball from that spot. After the player has taken relief and there is no longer interference for the stroke the player would have made, any further interference is a new situation.

For example, the player's ball lies in heavy rough in the general area approximately 230 yards from the green. The player selects a wedge to make the next stroke and finds that his or her stance touches a line defining an area of ground under repair. The player determines the nearest point of complete relief and drops a ball in the prescribed relief area according to Rule 14.3b(3) (Ball Must Be Dropped in Relief Area) and Rule 16.1 (Relief from Abnormal Course Conditions).

The ball rolls into a good lie within the relief area from where the player believes that the next stroke could be played with a 3-wood. If the player used a wedge for the next stroke there would be no interference from the ground under repair. However, using the 3-wood, the player again touches the line defining the ground under repair with his or her foot. This is a new situation and the player may play the ball as it lies or take relief for the new situation.

Interpretation Nearest Point of Complete Relief/4 - Player Determines Nearest Point of Complete Relief but Is Physically Unable to Make Intended Stroke

The purpose of determining the nearest point of complete relief is to find a reference point in a location that is as near as possible to where the interfering condition no longer interferes. In determining the nearest point of complete relief, the player is not guaranteed a good or playable lie.

For example, if a player is unable to make a stroke from what appears to be the required relief area as measured from the nearest point of complete relief because either the direction of play is blocked by a tree, or the player is unable to take the backswing for the intended stroke due to a bush, this does not change the fact that the identified point is the nearest point of complete relief.

After the ball is in play, the player must then decide what type of stroke he or she will make. This stroke, which includes the choice of club, may be different than the one that would have been made from the ball's original spot had the condition not been there.

If it is not physically possible to drop the ball in any part of the identified relief area, the player is not allowed relief from the condition.

Interpretation Nearest Point of Complete Relief/5 - Player Physically Unable to Determine Nearest Point of Complete Relief

If a player is physically unable to determine his or her nearest point of complete relief, it must be estimated, and the relief area is then based on the estimated point.

For example, in taking relief under Rule 16.1, a player is physically unable to determine the nearest point of complete relief because that point is within the trunk of a tree or a boundary fence prevents the player from adopting the required stance.

The player must estimate the nearest point of complete relief and drop a ball in the identified relief area.

If it is not physically possible to drop the ball in the identified relief area, the player is not allowed relief under Rule 16.1.

Substitute

To change the ball the player is using to play a hole by having another ball become the ball in play.

The player has substituted another ball when he or she puts that ball in play in any way (see Rule 14.4) instead of the player’s original ball, whether the original ball was:

  • In play, or
  • No longer in play because it had been lifted from the course or was lost or out of bounds.

A substituted ball is the player’s ball in play even if:

  • It was replaced, dropped or placed in a wrong way or wrong place, or
  • The player was required under the Rules to put the original ball back in play rather than to substitute another ball.
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).

General Penalty

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

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.

Opponent

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

Opponent

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

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).

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.

Opponent

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

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.

Opponent

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

 

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.

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.

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.

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.

  • 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.

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.

Opponent

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

 

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:

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.

Substitute

To change the ball the player is using to play a hole by having another ball become the ball in play.

The player has substituted another ball when he or she puts that ball in play in any way (see Rule 14.4) instead of the player’s original ball, whether the original ball was:

  • In play, or
  • No longer in play because it had been lifted from the course or was lost or out of bounds.

A substituted ball is the player’s ball in play even if:

  • It was replaced, dropped or placed in a wrong way or wrong place, or
  • The player was required under the Rules to put the original ball back in play rather than to substitute another ball.
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).

General Penalty

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

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.

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 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.

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
  • 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.

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).
Lost

The status of a ball that is not found in three minutes after the player or his or her caddie (or the player’s partner or partner’s caddie) begins to search for it.

If the search begins and is then temporarily interrupted for a good reason (such as when the player stops searching when play is suspended or needs to stand aside to wait for another player to play) or when the player has mistakenly identified a wrong ball:

  • The time between the interruption and when the search resumes does not count, and
  • The time allowed for search is three minutes in total, counting the search time both before the interruption and after the search resumes.

 

Interpretation Lost/1 - Ball May Not Be Declared Lost

A player may not make a ball lost by a declaration. A ball is lost only when it has not been found within three minutes after the player or his or her caddie or partner begins to search for it.

For example, a player searches for his or her ball for two minutes, declares it lost and walks back to play another ball. Before the player puts another ball in play, the original ball is found within the three-minute search time. Since the player may not declare his or her ball lost, the original ball remains in play.

Interpretation Lost/2 - Player May Not Delay the Start of Search to Gain an Advantage

The three-minute search time for a ball starts when the player or his or her caddie (or the player's partner or partner's caddie) starts to search for it. The player may not delay the start of the search in order to gain an advantage by allowing other people to search on his or her behalf.

For example, if a player is walking towards his or her ball and spectators are already looking for the ball, the player cannot deliberately delay getting to the area to keep the three-minute search time from starting. In such circumstances, the search time starts when the player would have been in a position to search had he or she not deliberately delayed getting to the area.

Interpretation Lost/3 - Search Time Continues When Player Returns to Play a Provisional Ball

If a player has started to search for his or her ball and is returning to the spot of the previous stroke to play a provisional ball, the three-minute search time continues whether or not anyone continues to search for the player's ball.

Interpretation Lost/4 - Search Time When Searching for Two Balls

When a player has played two balls (such as the ball in play and a provisional ball) and is searching for both, whether the player is allowed two separate three-minute search times depends how close the balls are to each other.

If the balls are in the same area where they can be searched for at the same time, the player is allowed only three minutes to search for both balls. However, if the balls are in different areas (such as opposite sides of the fairway) the player is allowed a three-minute search time for each ball.

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.
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.

Substitute

To change the ball the player is using to play a hole by having another ball become the ball in play.

The player has substituted another ball when he or she puts that ball in play in any way (see Rule 14.4) instead of the player’s original ball, whether the original ball was:

  • In play, or
  • No longer in play because it had been lifted from the course or was lost or out of bounds.

A substituted ball is the player’s ball in play even if:

  • It was replaced, dropped or placed in a wrong way or wrong place, or
  • The player was required under the Rules to put the original ball back in play rather than to substitute another ball.
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).

General Penalty

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

Ball-Marker

An artificial object when used to mark the spot of a ball to be lifted, such as a tee, a coin, an object made to be a ball-marker or another small piece of equipment.

When a Rule refers to a ball-marker being moved, this means a ball-marker in place on the course to mark the spot of a ball that has been lifted and not yet replaced.

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.

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.

Natural Forces

The effects of nature such as wind, water or when something happens for no apparent reason because of the effects of gravity.

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).

Opponent

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

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.

A substituted ball is the player’s ball in play even if:

  • It was replaced, dropped or placed in a wrong way or wrong place, or
  • The player was required under the Rules to put the original ball back in play rather than to substitute another ball.
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).

General Penalty

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