PGA Explanation On Carl Pettersson Penalty

Still waiting for video to appear on YouTube. Here's the PGA of America explanation:

Carl Pettersson was assessed a two-stroke penalty on the first hole of the final round of the 94th PGA Championship for a breach of Rule 13-4c when he moved a loose impediment lying in a lateral water hazard, while his ball was lying in the same hazard.

Pettersson hit his tee shot into the lateral water hazard to the right of the fairway. Before making the stroke, he asked the walking official, Brad Gregory, if he was allowed to touch grass, in the hazard, with his club, prior to the stroke.

Pettersson was correctly informed that he could do so, provided that he did not ground the club in the hazard. In making his backswing, Pettersson’s club brushed the grass behind the ball (not a breach) and at the same time moved a leaf (loose impediment), in breach of the Rule.

Pettersson was immediately notified by Gregory that there may have been a breach of Rule 13-4c, and that he (Gregory) wanted the stroke to be reviewed on video for confirmation.

PGA Rules Chairman, David Price, reviewed the stroke on video and confirmed that a loose impediment was moved during Pettersson’s backswing.

Pettersson was notified of the penalty as he left the fourth tee. His score for the par-4 first hole was a 6.
