AUGUSTA, Ga. — Sunday at the Masters began with Patrick Reed and Rory McIlroy in a final-round pairing that resurrected memories of the 2016 Ryder Cup at Hazeltine National Golf Club, where Reed got the best of McIlroy in a riveting singles match.

It ended with Reed rebuffing the challenges of two teammates from that victorious United States team, Rickie Fowler and Jordan Spieth, to win at Augusta National. It was Reed’s first victory in a major event, and it happened a short drive from where he led Augusta State to back-to-back N.C.A.A. Division I titles.

Reed closed with a one-under-par 71 for a 72-hole total of 15-under 273. He finished one stroke ahead of Fowler, who birdied six of his last 11 holes to post a 67, and two in front of Spieth, the 2015 Masters champion. Spieth nearly erased a nine-stroke deficit with a scintillating 64.

“In the past,” Reed said, “I put too much pressure on myself. I went out there and I tried so hard to get the ball in the hole, I tried so hard to hit the perfect shots. Going into this week I was just like, ‘Hey, it’s golf. Go play.’”
