ARDMORE, Pa. (AP) -- For the first time in 43 years the U.S. Open champion is an Englishman. Justin Rose claimed his first major championship by winning at Merion Golf Club, holding off Phil Mickelson and Jason Day. Rose closed with an even-par 70 for a 1-over total that made him the first Englishman to win the event since Tony Jacklin in 1970.
The tournament took a turn in Rose's favor on 15, where Mickelson and Hunter Mahan lost shots to fall out of a tie for first. Rose tapped in for par on 18 to maintain the lead, then waited until Mickelson missed a long birdie try on the final hole.
Mickelson bogeyed 18 for a 4-over 74 that left him tied for second with Day at plus-3. Mickelson carried a one-stroke lead into the final round before posting his sixth U.S. Open runner-up finish, extending his record.
Rose's final round consisted of five birdies and five bogeys. He missed a 5-footer for par at No. 3, but he sank long birdies on the 6th and 7th, then moved ahead of Mickelson with a 20-footer at No. 13.
Jason Dufner tied for the day's best round, carding a 67 to finish in a tie for fourth with Ernie Els, Billy Horschel and Hunter Mahan. Steve Stricker was in the hunt until his 76 left him five strokes back and tied with Luke Donald.
Tiger Woods completed a forgettable US Open with a 4-over 74 to finish 13-over par.
Shawn Stefani (STEH'-fan-ee) provided the shot of the day by acing the 299-yard 17th hole. He's the first golfer to make a hole-in-one in the five U.S. Opens held at Merion.
