Which American tour rookie was a surprise winner of the 2011 PGA Championship?

Keegan Bradley was the American PGA Tour rookie who became the surprise winner of the 2011 PGA Championship. He defeated Jason Dufner in a three-hole aggregate playoff at Atlanta Athletic Club in Johns Creek, Georgia.

The victory was remarkable because Bradley was playing in his first major championship. He had only recently established himself on the PGA Tour, making his win one of the most unexpected major breakthroughs in modern golf. Bradley finished the regulation rounds at eight under par, level with Dufner, before winning the playoff and claiming the Wanamaker Trophy.

Bradley also became the first golfer to win a major after making a final-round comeback from a large deficit in the modern format of the event. The 2011 championship was his first PGA Tour victory and his only major title. A common mix-up is to confuse the PGA Championship with the PGA Tour itself: the PGA Championship is one of golf's four men's major championships, while the PGA Tour is the main professional circuit in the United States.
