American Keegan Bradley ended a six-year drought when he won the BMW Championship in a play-off with Justin Rose yesterday, though the Englishman's consolation was to become World No 1.
Bradley parred the first extra hole to edge Rose after the pair had finished regulation on 20-under 260 at waterlogged Aronimink in suburban Philadelphia.
Rose missed a four-foot putt that would have extended the play-off.
"I can't believe this. It's so great," an emotional Bradley said after securing his fourth PGA Tour victory.
"It took a lot of hard work, a lot of people helping me."
Bradley (32) burst on to the scene with a Major victory at the 2011 PGA Championship, but had not won since 2012.
His victory capped a long week that left the course unplayable for the scheduled final round on Sunday.
Bradley carded a closing six-under-par 64 and hardly put a foot wrong until he bogeyed the final hole, a mistake that looked like costing him victory.
But Rose also dropped a shot at the par-four 18th, where his 15-foot putt for the win lipped out.
The pair finished one shot ahead of Americans Xander Schauffele and Billy Horschel.
Rory McIlroy finished two shots behind, while Tiger Woods was three back.
Rose got a lucky break in the play-off when his approach shot landed in a skybox but ricocheted back towards the hole and stopped just off the green.
However, he misjudged his putt through the soggy grass and it came up well short of the hole, before he missed the par putt.
That left Bradley to tap in for the win.
"I hit a great putt in regulation to win it," Rose said. "Just a poor play-off."
Speaking about his new ranking, he added: "That's obviously boyhood dream stuff, something I'm incredibly proud of. If you're trying to sum up my career in three sentences - World No 1 would be right up there."
