Rory McIlroy is one shot off the lead going into the third round of the US Open, but Shane Lowry has missed the cut at Brookline.
Meanwhile, Seamus Power is one over par after carding a 71 on Friday.
McIlroy recovered from a double bogey on the third hole in round two to card a 69 for a halfway total of four under par, one shot off the lead shared by Open champion Collin Morikawa and Joel Dahmen.
Defending champion Jon Rahm, Hayden Buckley, Aaron Wise and Beau Hossler are alongside McIlroy in third place, with Masters champion and world number one Scottie Scheffler part of a five strong group on three under.
“I think I have to go out with the mindset this week that I’m going to try to win my first (major) again,” McIlroy said.
“I’m playing as good a golf as I’ve played in a long time. I have a lot of experience. I’m in a good place. I’m really happy with where my game is at, and I think that’s the most important thing.”
Asked about the presence of some fellow top players on the leaderboard, McIlroy added: “It’s why we play. I sort of said it after Canada last week when I was (fighting for the title) with JT (Justin Thomas) and Tony (Finau).
“You want to go up against the best to try to bring the best out of yourself. And to see Collin and Jon and Scottie up there and whoever else, that’s what major championship golf is all about. That’s what competition is all about.
“I certainly don’t want it to be easy. I want guys to go out and shoot 65 so I have to go and shoot 64. That’s competition, and that’s at the heart of this game. I’m excited to be in that mix going into the weekend.”
