Rule 18/19 Ball Moved, Stopped or Deflected
Note: Any action by the player's caddie, his partner in a team event or a partner's caddie is deemed to be an action of the player.
Principle: If the ball was stationary at the time of the incident, it is to be replaced. If the ball was moving it is to be next played from where it came to rest.
Exception - ball deliberately interfered with: its original path is to be estimated and the ball is to be played from where it would likely have come to rest. If there is doubt as to where the ball might have come to rest, the player may opt to replay his stroke without penalty.
If the movement, stopping or deflection is caused by the player, one stroke is added to his score.
If a fellow competitor deliberately caused movement, stopping or deflection, one stroke is added to the fellow competitor's score.
If an opponent in match play (or his caddie) deliberately caused the movement, stopping or deflection, he loses the hole.
If a player accidentally causes his ball to move, such as when marking its position, the ball is replaced without penalty.
