McIlroy, carded four birdies and three bogeys in his lowest opening round since 2018, but ended the day five shots behind playing partner Scottie Scheffler and six adrift of clubhouse leader Bryson DeChambeau.

“It’s satisfying in one sense because it’s a decent start compared to the way I’ve played here recently, but I felt like it could have been two or three better,” McIlroy, who is making his 10th attempt to win a green jacket and complete the career grand slam, said.

“I think after the slow start making a few birdies around the turn was good. A little wasteful coming in. I had a good chance for birdie on 15 in the middle of the fairway and didn’t take that.

“Missed a shortish one on 16 and then the bogey on 17. But overall still not a bad score, and obviously a lot of golf left to play.

“I’m definitely not out of the tournament and not chasing anything tomorrow. I’m playing with Scottie so can keep an eye on what he’s doing and I’m looking forward to getting back out there.

“If you look at Scottie compared to the rest of the field, the amount of bogey-free rounds he shoots is phenomenal, and that’s the secret to winning major championships.

“I made three bogeys today, which is fine out there in these conditions, but just need to tidy it up a little bit to try to keep up with him.”
