Lingmerth, Dufner on top

Dufner, Lingmerth share first-round lead at Memorial.

Jason Dufner and David Lingmerth are tied at 65 after the first round of the Memorial Tournament.

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 in Dublin, Ohio, 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 three-putted after putting his tee shot into the water on the par-3 16th and made triple bogey. He threeputted from 4 feet on the sixth hole and made double bogey. And he didn’t make a single birdie in his round of 78.

It was the first time in nearly four years — since the Bridgestone Invitational in 2013 — that Johnson failed to make a birdie.

Day, who has yet to crack the top 25 at the club where he holds a membership, made bogeys on both par 5s on the back nine and was headed for a big score until he birdied his last two holes for a 75.

Daniel Summerhays joined Spieth at 66, while Justin Thomas and Lucas Glover were at 67.

Spieth missed the cut at The Players Championship and at his hometown event in the AT&T Byron Nelson, and he was on the verge of going home early at Colonial until turning it around. He wound up finishing one back of Kevin Kisner, and Spieth brought his form to Ohio.

“I felt like I scored the way I played today,” Spieth said.

De Vicenzo dies: Roberto De Vicenzo, known as much for a scorecard error at the Masters as his British Open victory that made him the first Argentine to win a major, has died. He was 94.

De Vicenzo died Thursday, the Argentina Golf Association confirmed on its website. It said De Vicenzo broke his hip last month at his home in Buenos Aires, and his health had been deteriorating since.

De Vicenzo amassed 230 titles worldwide, mostly in South America, but achieved fame on the biggest stages. He outlasted Jack Nicklaus to win the 1967 British Open at Hoylake for his only major. But even De Vicenzo could not forget the 1968 Masters, where he inadvertently signed for a higher score. Instead of a playoff, Bob Goalby was the winner.

European Tour: Renato Paratore of Italy shared the lead with England’s Max Orrin at 5-under 68 after the opening round of the Nordea Masters in Sweden.
