The R&A's Assistant Director Shona McRae explains the rules regarding Identifying your golf ball in the rough

Rules: Identifying Your Golf Ball in the Rough

This one must have happened to everyone at some point on the golf course.

Picture the scene - you've hit a strayed drive and see a golf ball in the cabbage just where you think yours might be, but neither a logo or any markings are visible.

Do you risk incurring a penalty for playing the wrong ball and hit it in the hope that it's yours?

Or do you gently lift it to formally identify it before placing it back where it lay?

GM Forum member '3offTheTee' had this query and the R&A's Assistant Director Shona McRae explains:

Q) In a recent stroke play event, one of our group’s balls was ‘lost’ in the rough. A fellow competitor found the ball and lifted it without asking or marking it to identify it. Is there a one-shot penalty to either the player who lifted the ball or the player whose ball it was, and would it be different in match play?

Best not to touch your opponent's or fellow competitor's ball if you think you've found it

A) Rule 12-2 contemplates that it is the player himself who wishes to lift the ball to identify it and details the procedure for doing so. In stroke play, if your fellow competitor moves your ball, touches it or causes it to move, there is no penalty and the ball must be replaced (Rule 18-4). Equally, in match play, if an opponent during the search for your ball moves, touches it or causes it to move, there is no penalty and the ball must be replaced. However, if your opponent, other than during a search for your ball, moves or touches it, it is he or she who incurs a penalty of one stroke and the ball must be replaced (Rule 18-3). Shona McRae
