What should a player do if his ball at rest is moved by a gust of wind?
Wind is not an “Outside Agency” (see Definition) and therefore, as a general rule, if a sudden gust of wind moves a player’s ball, there is no penalty and the ball is played from its new position. However, if this happens after the player has addressed the ball, the player is deemed to have moved it, he incurs a penalty stroke and the ball must be replaced (Rule 18-2b).
