Dustin Johnson Penalized for Grounding Club in "Bunker

Dustin Johnson blew up in the final round of the U.S. Open. On Sunday at the PGA Championship, his chances blew up on the 72nd hole when he grounded his club in an area he failed to recognize as a bunker.

Whistling Straits has, as the television viewers are constantly reminded, around 1,000 bunkers. Most of them are considered cosmetic - not in play. Some of them are tiny. Some of them are, in appearance, unlike bunkers you'll find anywhere else. But every single one of them is a bunker.

Johnson reached the 72nd tee with a 1-stroke lead. He hit a drive wild right - way right. So far right that Johnson found one of those weird little Whistling Straits bunkers that normally doesn't come into play. And he failed to recognize it as a bunker.
