An emerging star on the PGA Tour whose only missing achievement is contention in a major, the 31-year-old Homa finished at eight-under 272 at TPC Potomac at Avenel Farm.

He won for the fourth time overall, third in 15 months and second since he gave up his popular podcast.

"I just feel like I'm coming into my own. I'm starting to believe in myself a lot and that's all I can ask for," said Homa, whose next start will be in two weeks at the PGA Championship.

With his win last September in Napa, California, Homa joins Scottie Scheffler (four), Hideki Matsuyama (two), Sam Burns (two) and Australia's Cameron Smith (two) as multiple winners on Tour this season.

He also moves to sixth in the Presidents Cup standings, meaning he's in position to earn a return visit this September to the Wells Fargo's usual home, Quail Hollow in Charlotte, North Carolina.

Bradley started the day with a two-shot lead, gave it away on the par-5 2nd hole and took it back on the par-4 8th before Homa finally took command for good on the back nine.

A bogey on the closing hole gave Bradley a two-over 72 and a tie for second with Cameron Young and Matt Fitzpatrick.

Australia's Jason Day, the first and second round leader, closed with a 70 to finish at one-under in a tie for 15th place.
