1990 -- Medinah Country Club
Eleven years after his last U.S. Open win, Hale Irwin added another title to his resume in 1990. At the conclusion of the final round, Irwin and Mike Donald were tied at 8-under par, and they remained tied after the 18-hole playoff. Irwin captured the title in dramatic fashion with an 8-foot birdie putt on the 19th hole that made the 45-year-old the oldest U.S. Open champion.
