The 29-year-old finished at 10 under par, one shot ahead of McIlroy, to win his maiden major and the $3.6 million (£2.8 million) winner’s prize.

Scottie Scheffler, the world’s top player, finished third and two shots further down.

Rickie Fowler, who shared the overnight lead, dropped to a dismal five-over 75 and tied for fifth place.

Cameron Smith, the current Open winner, finished the round one stroke ahead of Fowler after making three birdies on the back nine amid a late surge. Fowler had seven total bogeys during the round.

Min Woo Lee of Australia and Tommy Fleetwood finished the tournament at five under par. The Englishman shot the lowest round of the day, a seven-under 63, thanks to eagles on holes 6 and 14.

The 32-year-old, who also made four birdies, made history by shooting 63 twice at the US Open, becoming only the fourth player overall (after Greg Norman, Vijay Singh, and Brooks Koepka) to do so.
