Masters champion Jordan Spieth kept his nerve to claim the U.S. Open title Sunday in a dramatic finish at Chambers Bay.
Spieth had birdied the final hole to finish on five-under 275, but then watched as fellow American Dustin Johnson three-putted from 12 feet on the 18th to finish one shot behind with South African Louis Oosthuizen in a tie for second.
Johnson’s eagle putt for outright victory on the par-five closing hole went adrift, and he then missed the short birdie putt which would have forced a playoff on Monday.
The 21-year-old Spieth is the youngest U.S. Open champion since Bobby Jones in 1923 and only the sixth man to double up, Tiger Woods being the last in 2002.
He is now halfway to the grand slam, with the British Open and PGA Championships to come later in the year.
Former British Open champion Oosthuizen charged through the back nine in 29 shots for a 67 to set a testing clubhouse target of four-under 276.
Joint overnight leader Branden Grace, tied in the lead with Spieth at five-under playing the 16th, made a double bogey to end his hopes and the eventual champion pulled clear as he birdied.
But Spieth then showed his first signs of fallibility by making an ugly double bogey five on the short 17th, before recovering with a battling birdie on the 18th.
Australian Jason Day, so brave in battling vertigo in rounds two and three, fell away to finish on level par after starting the final round tied with Spieth, Johnson and Grace.
Two earlier starters had threatened to turn the tournament on its head, with world number one Rory McIlroy moving to two-under-par when he rolled home a monster 72-foot birdie putt on the 13th.
It took the Northern Irishman to six-under for the day, but he missed a short birdie opportunity on the next and then frittered two shots away to close with a 66 and level par.
Behind McIlroy, an even bigger threat emerged as former Masters champion Adam Scott of Australia, with Woods’ old caddy Steve Williams on his bag, was quietly moving up the leaderboard.
When he birdied the final hole for a best of the week 64, Scott had set a challenging three-under 277 total for the later starters to beat.
