A Guide to the Rules on Clubs and Balls

General (Rule 5-1)

Rule 5-1 provides that the ball that a player uses must conform to the Rules and that the use of a ball which does not conform to the Rules will result in disqualification. However, the player would have to make a stroke at a non-conforming ball in order for the disqualification penalty to apply (see also Decision 5-1/3 in Decisions on the Rules of Golf).
