FARMINGTON, Pa. (AP) -- The collapse never came, even as a once-sizable lead dwindled to a single precarious stroke. This time, Sunday didn't crush Jason Gore. It belonged to him. Gore, whose last-day unraveling already is part of U.S. Open lore, stood up to the 84 Lumber Classic field Sunday with big drives and steely nerves to win on the PGA Tour barely a month after being stuck in golf's minor leagues. Gore's four-stroke lead with five holes to play was down to one over runner-up Carlos Franco by No. 18, but Gore landed his approach shot on the 468-yard par 4 on the lower fringe of the green. With a playoff looming if he didn't get up and down, Gore deftly lagged his putt from 91 1/2 feet to within 22 inches, and tapped in for a final-round 2-under 70, a $792,000 paycheck and the PGA Tour victory he once thought might never come. His 14-under 274 denied Franco (69) his first PGA Tour victory since 2001 and was three shots better than third-place finisher Ben Crane (67). Gore never finished higher than 18th during two previous stays on the PGA Tour, in 2001 and 2003. Now, he joins Paul Stankowski (1996) as the only golfers to win on the developmental Nationwide and PGA tours in the same year. The portly, big-swinging Gore is the first to do so after earning the automatic in-season promotion that goes to any three-time Nationwide winner. Now, all those public course duffers who think they could make the leap to golf's big leagues have a new hero to go with John Daly. Gore, 31, looks as much like a spectator as he does a pro, and his caddie wears not a Nike or a Titleist cap, bur one plugging Pabst Blue Ribbon beer. Jason Gore, this one's on you. And this wasn't an ordinary post-majors win, either, with most of the big names long since gone. The field for the $4.4 million event was unusually strong with four of the top six money winners, including Phil Mickelson and 2004 champion Vijay Singh. Gore opened a two-shot lead through 54 holes following a 5-under 67 Saturday at the 7,416-yard Mystic Rock course, then never trailed on a Sunday that was a polar opposite of the U.S. Open. Franco, playing one group ahead of him, tied him briefly with a birdie on the par-5 No. 8, but Gore answered minutes later with his eagle on the same hole after hitting his approach shot to 12 feet. That Gore seemed at home at a tournament where big hitters own an advantage and Daly is the unofficial host is no coincidence. Gore's mother, Kathy, grew up in Pittsburgh and moved back there four years ago after Jason's father died. Gore first played the game during a summertime shagging balls and driving golf carts at the public Manor Valley course, a suburban Pittsburgh course where his late uncle, John Kovach, was the pro. And Gore began getting his game together not far from Pittsburgh following his final-round 14-over 84 at the U.S. Open. A month later, he won the Nationwide Tour event in nearby Bridgeport, W.Va., the first of three consecutive wins. In that forgettable U.S. Open round, he bogeyed more than half the holes, with three double-bogeys and a triple. On this much different Sunday, he didn't have a bogey until the par-4 No. 14, when the four-stroke edge was cut to three shots. Franco, who had only two bogeys in four rounds, got to within a stroke with a birdie on No. 16, and Gore bogeyed the par-3 17th by missing an eight-footer for par.
