Tim Simpson capitalized on playing partner Donnie Hammond's bogey on the 18th hole Saturday for a one-shot victory in the Disney tournament at Lake Buena Vista, Fla.
Hammond, seeking his second consecutive PGA Tour victory, hit his drive on the par-4 final hole behind a tree. He put his second shot into a bunker, chipped up 20 feet short of the pin and two-putted.
Simpson, who saved his share of the lead with a 12-foot par putt on No. 17, tapped in for a par on the final hole for a two-under-par 70 and a 72-hole score of 272. Hammond had a 71 for 273.
It was Simpson's second victory this year and he collected $144,000.
Paul Azinger, who began the day four strokes back, made nine birdies on the first 12 holes to take a two-stroke lead at 17-under.
But Azinger bogeyed three of the next four holes and finished with a 68 and a tie for third at 274 with Kenny Knox and Fred Couples, who each had 70s.
Al Geiberger, Dave Hill, Charles Coody and Billy Casper shared the lead at five-under-par 139 after two rounds of the TransAmerica seniors tournament at Napa, Calif.
Jim Ferree, who shot the day's low round of 68, and Bob Charles were one stroke behind at 140.
Hill and Casper, playing in the same threesome, both eagled the par-5 18th hole to finish with rounds of 70.
Geiberger shot a 69, and Coody matched par of 72.
