DUBLIN, Ohio — Jason Dufner putted for birdie on every hole until the last one at the Memorial, a game so under control it looked as simple as breathing.

Even with a bogey on the final hole, Dufner had a 7-under 65 for his best score Thursday at Muirfield Village, giving him a tie for the lead with David Lingmerth. They were one shot ahead of Jordan Spieth, whose short game is starting to return with the U.S. Open around the corner.

Lingmerth, whose first PGA Tour victory came at the Memorial two years ago, also bogeyed his last hole on an ideal day for scoring.

Starting quickly at the Memorial is nothing new for Dufner lately. He opened with a 66-67 two years ago before fading on the weekend. Last year, he opened with a 68.

“I can put a couple of rounds together here,” Dufner said. “But I’m looking for more than that this week. Hopefully, we can keep it going for four.”

Dustin Johnson and Jason Day want to make sure they get to play for rounds.

Johnson didn’t make a single birdie in his round of 78. Day carded a 75.
