1. Greg Norman, 1996 Masters
The choke:At the ninth hole, Norman's wedge fell short of the hole and rolled back 30 yards. He made bogey and it was all downhill from there. Norman made three consecutive bogeys followed by a double bogey. In 20 minutes and over six holes, Norman had surrendered six shots. He lost by five strokes.
Editor's Note: This entry originally misstated that Norman had won the U.S. Open in 1996, among other successes that year. He has never won the U.S. Open. We regret the error
