The U.S. Open has been the stage for some of the most stirring moments in golf history.
No one will ever forget the 2008 Open at Torrey Pines, where Tiger Woods, who was basically playing on one leg, defeated Rocco Mediate in a gripping tournament that concluded with a 19-hole playoff.
Merion Golf Club, the site of this year's Open, has had its own moments. It includes a 1971 playoff victory by Lee Trevino over Jack Nicklaus and a 1950 playoff win by Ben Hogan in his comeback less than two years after a near-fatal car accident.
Then there is the other side of the coin.
The U.S. Open also has seen its share of collapses. There is as much agony as ecstasy at the event. Here are the most memorable—forgettable?—moments in Open history, where players have snatched defeat from the jaws of victory.
