Rory McIlroy believes his "controlled" and "disciplined" start will stand him in good stead at the US Open, where he is eyeing a first major triumph in 10 years.

The three-time major winner opened with a bogey-free opening round of 65 at Pinehurst for a share of the lead with Patrick Cantlay.

It is a good omen for McIlroy, who has gone on to lift the trophy on all three occasions he has started a major without bogeying - achieving the feat at the 2011 US Open, 2012 PGA Championship and 2014 Open Championship.

The 35-year-old also equalled his best-ever start at a US Open, having posted 65 on the way to his 2011 victory and second-place finish 12 months ago.

"It's nice to see your name at the top of the leaderboard after the first day of a US Open," McIlroy, who hit five birdies including two in the last three holes, told Sky Sports.

"I felt like I played a really solid, controlled round of golf. I just stayed disciplined and when I got myself in trouble, I took my medicine, two-putted.

"This is the whole thing about a US Open, it's trying to keep clean scorecards like this. I'm pretty sure I'm not going to keep it bogey-free for the rest of the week. But it's not about how many birdies you make, it's about how many bogeys you don't make.

"I had a run of pars from the 11th through to 15th where I had chances and wasn't able to convert. But I feel like the patience I showed over those five holes was rewarded with two birdies in the last three - a great way to finish.

"I went through a run for a while where my starts at major championships weren't very good. I probably got myself a little too worked up at the start of the week.

"Certainly, the major championships that I've won or the ones that I've played well at, I've always seemed to get off to a good start, and it's nice to get off to another one."
