American Billy Horschel birdied the 18th hole to claim the BMW PGA Championship title in a tense finish on Sunday in a tournament with huge implications for Europe's Ryder Cup team.
Horschel was tied for first in a group at 18 under par as he stood over his third shot at the par-5 18th at Wentworth but produced a sensational wedge shot for a nailed-on birdie to complete a sizzling round of 7-under 65.
Englishman Laurie Canter needed a birdie on 18 to force a playoff but was unable to do so and ended in a tie for second alongside Welshman Jamie Donaldson and Thailand's Kiradech Aphibarnrat, who shot a superb closing 64.
Horschel, whose bag sports the colours and emblem of English Premier League club West Ham United, is only the second American to win the title, following in the footsteps of Arnold Palmer.
Afterwards he said he would celebrate by going to dinner with West Ham's England international Declan Rice.
"I am speechless really, and that's rare," Horschel, who has missed the U.S. Ryder Cup team, said. "To win this event means a lot, this is like the Players' Championship. I knew if I could birdie one of the last three holes I could win and one was enough."
Apart from the title at stake in the European Tour's flagship tournament, the race to nail down the four remaining automatic spots on Europe's team for this month's Ryder Cup offered an intriguing subplot throughout the week.
Austrian Bernd Wiesberger, who required a top-50 finish to book his Ryder Cup debut, ended with a level-par 72, which was enough for a share of 20th and a seat on the plane.
"It's unreal, you know, it was really tough out there today," Wiesberger told Sky Sports. "You try to stay away from all the noise, but it was difficult. I had to grind. But at the end of the day, I'm really proud and relieved to make the team."
Justin Rose did not claim the title, which would have elevated him into the Ryder Cup team on merit, although his majestic final-round 65 for a share of fourth place at 16 under is likely to have impressed Europe captain Padraig Harrington.
Rose, a stalwart of several Ryder Cup victories, almost produced an albatross on the 18th when his second shot ended just a foot from the hole.
Ireland's Shane Lowry was left sweating on receiving a captain's pick for the Ryder Cup after failing to secure the top-eight finish he required to grab an automatic spot.
Lee Westwood's dismal round of 77 had opened the door for Lowry to edge above him in the race to grab one of the last remaining places, but Lowry faltered on the back nine.
After moving into a tie for fifth place, Lowry bogeyed the 14th and followed that with a double-bogey, ending at 12 under and in 17th place.
