SHEBOYGAN, Wisconsin (AP) — Martin Kaymer has won the PGA Championship in a three-hole playoff that did not include Dustin Johnson, who was penalized two strokes for grounding his club in a bunker on the last hole.

Johnson had a one-shot lead playing the final hole at Whistling Straits when he drove into a tiny patch of sand where the gallery had been walking all week. Johnson grounded his club, unaware he was in a bunker.

He missed a 7-foot par putt to seemingly slip into a three-man playoff with Kaymer and Bubba Watson. But the two-shot penalty sent him into a share for fifth.
