KOHLER, Wisconsin (Reuters) - Germany's Martin Kaymer held his composure to win his maiden major title in a gripping two-way playoff with American Bubba Watson for the 92nd U.S. PGA Championship at Whistling Straits on Sunday.

With American Dustin Johnson having earlier been eliminated from the playoff after being assessed a two-stroke penalty, Kaymer went on to clinch the prized Wanamaker Trophy over three extra holes.
