Sweden’s Carl Petterrson will be advised by his managers to review video footage of an incident at the first hole of his final round of the PGA Championship.

Pettersson was assessed a two-stroke penalty 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.

The Swede hit his tee shot into the hazard to the right of the fairway but in making his stroke, Pettersson asked the walked official, Brad Gregory, if he was allowed to touch grass, in the hazard, with his club, prior to the stroke.

Pettersson was advised he could, provided that he did not ground the club in the hazard.

But in making his backswing, Pettersson’s club brushed the grass behind the ball (not a breach) and the same time moved a leaf (loose impediment), that is in breach of the Rule.

Pettersson immediately advised Gregory he may have breached the rule and wanted it reviewed on video.

The incident was reviewed and with Pettersson being informed on the fourth hole that the impediment had indeed moved.

So instead of a par four, Pettersson had to put down a double bogey six.
