Annika Sorenstam filmed this little snippet explaining your options after a golf ball lands in a water hazard.
Annika Sorenstam feature sin this nice video on the rules pertaining to playing from water a hazard. Brian Davis got into some trouble while playing from a hazard in a playoff against Jim Furyk in last week’s Verizon Heritage tournament. He knocked a reed on his back swing while making the stroke and immediately called the rules official for a ruling.
Rule 13-2 states that a player may move, bend or break anything growing or fixed in making a stroke or in the backward movement of his club for a stroke and the stroke is made. But Davis had made contact with a “loose impediment” on his backswing. A “dead palm frond” was the culprit.
The video shows the situation in more detail but in summary; you can brush or bend anything in a hazard that is growing but do not brush or bend anything that isn’t.
Thanks to the great Barry Rhodes at Rules of Golf for clarification.
