American Webb Simpson with the US Open trophy
American Webb Simpson clinched his maiden major title with victory on an absorbing final day of the US Open.
The 26-year-old beat Northern Ireland's Graeme McDowell and fellow American Michael Thompson by one shot at a foggy Olympic Club in San Francisco, reports the BBC.
Simpson shot 68 to set the target at one over and watched as 2010 champion McDowell missed a 25ft putt to force a play-off on the 18th.
Lee Westwood took 73 for three over, while Tiger Woods (73) was seven over.
Simpson, who climbs to fifth in the world, becomes the 15th different major winner in a row, the ninth straight first-time winner and the third consecutive American to win one of golf's grand slam events.
"I've never felt nerves like I felt today," said Simpson, who was pipped to the US money list title by England's Luke Donald last year. "I had to hit my legs because I couldn't feel them.
"I probably prayed more the last three holes than I ever did in my life."
Starting the final day four shots behind co-leaders McDowell and Jim Furyk, Simpson made his move with a spell of four birdies in five holes from the sixth.
Parring his way home, he bettered the clubhouse mark of first-round leader Thompson, who shot 67, and took the outright lead when Furyk, who had been in front all day and led by two at one stage, bogeyed 16.
Both 2003 champion Furyk and McDowell had a chance to force an 18-hole play-off on Monday, but the 42-year-old American finished with another bogey via the left bunker on 18 for a 74 to end two back and McDowell could only make par for a 73.
"It was grind and a slog, but I'll be back," said the 32-year-old McDowell, who had hoped to make it three Northern Irish wins in a row following Rory McIlroy's success last June.
"There's a mixture of emotions inside me right now, disappointment, deflation, pride but mostly just frustration."
Furyk, whose hooked drive on the par-five 16th sparked his downfall, said: "I don't know how to put that one into words, but I had my opportunities and my chances and it was right there.
"On that back nine, it was my tournament to win. I've only got myself to blame."
Ireland's Padraig Harrington put up a serious challenge for a fourth major title and first since 2008 with a run of five birdies in 11 holes. But needing a birdie at the last to join Thompson, he ran up a bogey five after finding sand with his approach and ended with a 68 to finish three over.
Americans David Toms (68), John Peterson (70) and Jason Dufner (70) also finished three over with 1994 and 1997 US Open winner Ernie Els on four over.
