Both entered the playoff at 5 under. Montgomerie entered the third extra hole with a one-shot lead, then made a putt on No. 18 to par the hole and claim the win.
Montgomerie became the fifth golfer to win both the PGA Championship and U.S. Senior Open in the same year. He led at the end of the first and second days of the Senior Open, but entered the final round four shots behind Sauers and shot a 2-under 69 to force the playoff.
It was the first playoff at a U.S. Senior Open since 2002, when Don Pooley beat Tom Watson in a five-hole playoff.
