Duffy Waldorf birdied the last two holes of regulation to force a playoff, then made another birdie on the first extra hole to beat Dennis Paulson and win in Harrison, N.Y.
Waldorf, a gallery favorite thanks to his colorful caps and friendly manner, was only seeking to get his 18-foot putt for a 4 close on the playoff hole, the par-5 18th. Paulson was already lying 5 after pushing his 3-wood right on his second shot and taking two chips to get the ball 25 feet from the cup. He missed his par putt.
Waldorf won for only the second time on the PGA Tour and the $450,000 check was the biggest of his career.
Paulson, who was seeking the first win of his career, had seemed to be in command with a two-shot lead less than an hour earlier.
But then Waldorf dropped a wedge about six feet from the cup on the par-4 17th and made the putt to get within one. On the 18th, Waldorf hit two drivers to a trap short of the green, then blasted a sand iron to four feet. He rolled the ball in to force the playoff.
Paulson, who closed with a 4-under 67, and Waldorf, who had a 71, finished regulation tied at 8-under 276. Chris Perry was one stroke back after a 70, while Scott Hoch was alone in fourth at 278 after a 69.
Paulson, better known as a one-time long-driving champion than for his touch around the greens, had emerged from a tightly bunched group of contenders with a six-foot birdie on 13, a three-footer on 14 and a 12-footer on 17. That offset a bogey on 15.
