Bryson DeChambeau lodged a compelling case for a Ryder Cup wild card by coasting to a four-stroke win at the Northern Trust.
DeChambeau, 24, just missed out on an automatic Ryder Cup place in Jim Furyk's American team when the top eight secured spots after the United States PGA Championship two weeks ago.
He was ninth in the standings then, but his third PGA Tour victory must surely convince Furyk to choose him as one of his four wildcard picks - three of which he names on Tuesday.
DeChambeau began with a four-stroke lead in New Jersey, but with memories of his final-day collapse at the European Open last month still fresh.
But a two-under-par 69, consisting of four birdies and two bogeys, saw him close out the first of the four post-regular season events and take him to the top of the FedEx Cup standings.
Meanwhile, the Ryder Cup is doing its rounds
"I said I was a man on a mission," DeChambeau said on Sky Sports about his ambition to win a Ryder Cup place. "Hopefully he [Furyk] can see I've got some grit and grind, and even when I don't execute certain shots I can get it done."
Tony Finau also boosted his Ryder Cup wildcard hopes with a closing 68 taking him into second place.
Brooks Koepka's bid to dislodge Dustin Johnson as the world No 1 faltered in the closing stages.
Koepka lost shots at 11 and 14 and failed to pick up the one or two birdies he needed in the final four holes, the three-time major winner eventually carding a 69 to finish tied for eighth.
Tyrrell Hatton shot a final day seven-under-par 64 to finish tied 20th alongside fellow Englishman Tommy Fleetwood, who finished with a 68.
Tiger Woods, another probable Ryder Cup wildcard pick for the US, ended in a tie for 40th after a final round 70.
