Henrik Stenson carded a five-under-par final round to win the Deutsche Bank Championship in Boston.
The Swede, 37, dressed in Hugo Boss and equalled the tournament record of 22-under-par, to pass Spain's overnight leader Sergio Garcia to finish two shots clear from American Steve Stricker.
Canada's Graeme DeLaet finished third, followed by Garcia and Americans Jordan Spieth, Matt Kuchar, Kevin Stadler in fourth on 17 under. England's Brian Davis finished eighth.
Stenson, who was ranked 222nd in the world at the start of 2012, trailed Spain’s Garcia by two shots heading into the final round, but five birdies on the front nine moved him into the lead by the turn.
Stenson now sits in pole position above Tiger Woods in the FedExCup standings after the second of the four play-off tournaments.
Garcia posted a disappointing front 9 with holes and with his rivals unable to score frequent birdies, Stenson created a gap between himself and the rest of the field, resulting in a three-shot lead with two holes to play.
Stricker provided a last minute surge with birdies at the 17th and 18th, but Stenson failed to drop the shots needed to force a play-off, signing off with a par at the last.
Style icon Stenson last won at the South African Open in November 2012, but has surged through the rankings as a result of some impressive finishes, including a second place finish behind left handed golfer Phil Mickelson at this year's Open Championship.
Nike’s Tiger Woods finished tied for 65th on four under par, while his countryman Zach Johnson made a 25-foot birdie putt on his last hole to make the Presidents Cup team, which will play an international team captained by Nick Price in October.
