Patrick Cantlay was close to winning in his last two starts.
After two consecutive third-place finishes, Cantlay finally topped the leaderboard at the Memorial Tournament.
Cantlay, who now has two PGA Tour wins, finished the weekend 19 under. He had his best round Sunday, 8-under 64, to break away from the crowded field.
"It feels great," he said. "It's been a while since I've won, almost a year and a half, and being able to win on this golf course, a golf course that I really like and in front of Jack [Nicklaus] and making that putt on the last hole, I can't tell you how good it feels.
"It validates my confidence that I can play with the best players in the world. Beating a field like this on a big golf course like this, this is very similar to a major championship set up."
Cantlay, 27, was bogey free in his final round and fired off eight birdies. He went on to card three straight pars on his final three holes, including his final putt to solidify his lead as there was still one group left on the course.
He had to fend off the likes of Adam Scott and Martin Kaymer, who finished second (17 under) and third (15 under), respectively. Scott nearly caught up to Cantlay after three consecutive birdies on the 14th through 16th holes put him two strokes off the lead.
Birdie at the 14th hole.

Scott was close to a birdie putt on the par-4 17th hole but the ball skirted just past the hole. He saved par but was unable to eagle 18. Scott matched his best finish of the season.

Kaymer, who was the 54-hole leader, fell down the leaderboard after his round was sullied with four bogeys.
Kevin Streelman finished in fourth place (13 under), Marc Leishman in fifth (12 under) and Hideki Matsuyama dropped into sixth place (11 under). Jordan Spieth joined Jason Dufner in a tie for seventh place (10 under) and Tiger Woods highlighted the four-way tie for ninth place (9 under).
Woods finished his final round 5-under 67.
He opened the day with five birdies on the front nine, including back-to-back birdies on the 2nd and 3rd holes and again right before the turn on the 7th and 8th holes. Woods carded two more birdies on the back nine and a pair of bogeys to finish the day.
"I played really well today. It was fun," Woods said. "I hit the ball so crisp and so solid and I made some nice putts. ... I had it rolling for a little bit."
The PGA Tour season will continue with the RBC Canadian Open followed by the U.S. Open beginning June 13.
