After shooting a 61 on Saturday to take a four-stroke lead, Perry had six birdies and two bogeys in the final round to finish at 18-under 198. He became the first player to successfully defend a title in the tournament's 23-year history, winning for the eighth time on the 50-and-over tour.
Last year, Perry made a 15-foot birdie putt on the final hole to beat Langer by a stroke at TPC Twin Cities.
Langer closed with a 67, and Dunlap and Sutherland each shot 68.
