Keegan Bradley’s victory at the Travelers Championship in Connecticut marks his sixth PGA Tour title overall.
The 37-year-old American finished on 23 under overall after shooting a final-round 68 at two under par.
As a result, the 2011 PGA Champion was three shots ahead of the field. Zac Blair, a fellow countryman, finished second with Brian Harman after shooting an outstanding eight-under 62.
Rory McIlroy of Northern Ireland came in at the end in a tie for sixth.
The 34-year-old played a 64 to finish at 18 under par overall, five strokes behind Bradley. He had five birdies in his first seven holes to move up the leaderboard, but a bogey on the ninth hole and just two gains on the back nine prevented him from catching Bradley.
