Scottish golfer Marc Warren has said that he was rewarded by patience in his opening round at the US Open.
The 34-year-old hit a round of 68 and sits joint-seventh on two-under-par at Chambers Bay.
He told Sky Sports News: "Anything under par in a US Open is a pretty good score, so to shoot 68 today on a course like that was very nice.
"I got a couple under early on and after that I just tried to stay as patient as I possibly could. When you look at the leaderboard and see guys on five or six under it's easy to get carried away and try to chase a really low score, but that's a very dangerous game to play.
"You're better off leaving them to it because you know this course will force you into making some mistakes along the way. Level par is always normally going to be a pretty decent score in the US Open. That's the way the USGA set their courses up, so you have to adapt, play conservatively for the most part, keep the mistakes to a minimum and try to take your chances if and when they come along."
Dustin Johnson and Henrik Stenson are the overnight leaders on five-under.
