Merion C.C. 1950
Ben Hogan was one shot behind Lloyd Mangrum on the 16th hole of the U.S. Open playoff. Lloyd Mangrum was about to putt when he noticed a bug on his golf ball. Without thinking, he picked up the ball and blew the insect away. Mangrum incurred a two-shot penalty for lifting and cleaning his ball which was against the rules at that time. Hogan went on to win the playoff.
