Martin Kaymer returns as the defending champion after running away with an 8- shot victory at Pinehurst No. 2 last year. It was the German's second career major title as he also took home the 2010 PGA Championship at Whistling Straits. Kaymer also became the first player ever to win the Players and U.S. Open in the same year.
Eleven players that are qualified for this U.S. Open also played in that U.S. Amateur. Topping that list is Masters champion Jordan Spieth, who failed to make it to the match play portion of that championship.
