The 1955 U.S. Open was the 55th time the tournament was played, and in a famous upset journeyman Jack Fleck beat Ben Hogan in a playoff.
Winner: Jack Fleck, 287
Where it was played: Olympic Club in San Francisco, California
Tournament dates: June 16-19, 1955
Leader after first round: Tommy Bolt, 67
Leader after second round: Tommy Bolt and Harvie Ward, 144
Leader after third round: Ben Hogan, 217
Notable Notes: Chasing what would be a record-setting fifth U.S. Open title, Ben Hogan led by one over Sam Snead and Julius Boros entering the final round. But it wasn't those two stars who tied Hogan and forced an 18-hole playoff, but little-known Jack Fleck. Fleck made an 8-foot birdie putt on the 72nd hole to tie Hogan at 287. Fleck was given almost no chance to win the playoff, but after starting with seven consecutive pars he reeled off three straight birdies on holes 8-10, taking a 3-stroke lead. And that's how it ended, Fleck shooting 69 to Hogan's 72.
