Sergio Garcia completed a final round of 66 to capture the weather-delayed Wyndham Championship on Monday, his first victory on the PGA Tour in four years.
The win also ensures that the 32-year-old will qualify for Europe's Ryder Cup team having missed out on playing in the last match at Celtic Manor two years ago.
While Garcia is now assured of a sixth cap for the Europeans, Ian Poulter will be left requiring a wildcard pick once again having been nudged out of an automatic place by the Spaniard.
Garcia pulled clear of his rivals with a run of four birdies in five holes over the course of the back nine at Sedgefield Country Club and eventually finished at 18-under-par, two clear of South Africa's Tim Clark in second.
Bud Cauley took third place at 15-under, with two more Americans, Chad Campbell and Jimmy Walker, and Sweden's Carl Pettersson sharing fourth a shot further back.
Nicolas Colsaerts boosted his Ryder Cup prospects as he took advantage of his special invitation to the event to finish in a tie for seventh after also closing with a 66.
With Poulter widely expected to claim one of European captain Jose Maria Olazabal's two picks, the Belgian is favourite to get the other - should he require it.
Unlike Garcia and Poulter, who are involved in the start of the FedEx Cup play-offs, Colsaerts still has this week's Johnnie Walker Championship at Gleneagles to come and a third place finish there would take him ahead of German Martin Kaymer, the player now in the last automatic spot.
Colsaerts boosts Cup hopes
England's David Lynn, the surprise runner-up in the final major of the season, and Spain's Rafa Cabrera Bello also have a chance in Scotland to earn a cup debut, but they each need to win.
Colsaerts was another of the 38 players unable to finish on Sunday and instantly made birdies at the 13th and 14th on his return.
They lifted the 29-year-old into a tie for third, but he closed with four pars and subsequently slipped back down the leaderboard.
Garcia began his final burst with a superb 136-yard approach to within 18 inches of the flag on the 13th, got up and down from sand at the long 15th, hit his tee shot to two feet on the 166-yard next and then fired in another iron to six feet at the 17th.
A four-shot lead was reduced when Clark holed out from just short of the green for birdie on the last and there was still work to be done when Garcia drove into the trees there.
He had to chip out and was still not on the green in three, but got down in two more for an 18-under-par total of 262.
"I am proud of the way I played coming in," Garcia said.
"Obviously I won a couple of times last year in Europe, but it's been a while here (in the United States) and it feels great.
"I hit some really good shots and made some nice four or five-footers when I had to. I'm very happy about the way the week has gone."
