The 2012 United States Open Championship was the 112th U.S. Open, played June 14–17 at the Olympic Club in San Francisco, California. Webb Simpson won his first major title, one stroke ahead of runners-up Graeme McDowell and Michael Thompson. This was the fifth U.S. Open at the Olympic Club, all played at the Lake Course. In 1955, unheralded Jack Fleck defeated Ben Hogan in an 18-hole playoff. In 1966, Billy Casper staged one of the greatest comebacks in U.S. Open history, erasing a seven-stroke deficit on the final nine holes to tie Arnold Palmer, then prevailed in an 18-hole playoff. In 1987, Scott Simpson won by a stroke over 8-time major winner Tom Watson. In 1998, Lee Janzen won his second U.S. Open, one stroke ahead of Payne Stewart. Wikipedia
