He produced a shot for the ages to win his maiden major at Brookline a year ago and showed he still had magic in his hands when he delivered a shot straight onto the green at the Los Angeles Country Club.

The Briton glanced away after the drive but fans were able to catch his attention as they cheered with approval while the ball slid into the hole seamlessly.

Frenchman Matthieu Pavon and American Sam Burns each recorded an ace in the opening round on 15 as well.

Fitzpatrick is the first defending champion to make an ace at the US Open and this year marks only the second time in the tournament's history in which there were three or more, after the 1989 tournament at Oak Hill.

It was the burst of good fortune that Fitzpatrick needed, as he started on the back nine after carding a one-over 71 on Thursday.
