Jordan Spieth survived a double-bogey on 17 to win the U.S. Open on Sunday, after Dustin Johnson missed the opportunity to force a play-off.
Spieth claimed consecutive major titles - after his maiden major victory at the Masters in April - carding a one-under 69 to finish on five under for the tournament.
That was just enough for the 21-year-old American, who finished a shot ahead of Louis Oosthuizen and Johnson to become the first player to win the Masters and U.S. Open in the same year since Tiger Woods in 2002.
While Adam Scott, Cameron Smith and Branden Grace claimed a share of fourth at three under overall.
Spieth looked to be in complete control heading to the 17th tee at Chambers Bay Golf Club but his first shot found the rough and after an impressive recovery shot on the par-three hole, he rolled his par putt close but then missed his bogey effort to drop back to four under.
Johnson, who carded three bogeys on the opening four holes of the back nine to drop to three under, birdied the 17th to put the pressure on Spieth.
But when handed the opportunity to win the tournament - and then force a play-off round on Monday - Johnson saw consecutive putts role past the hole on the 18th green, meaning the 31-year-old remains without a major title, despite nine top-10 finishes.
Oosthuizen shot a three-under 67 to finish tied for second with Johnson, while earlier, Scott posted a 64 to surge up the leaderboard and put himself in contention for the trophy.
It was not such a good day for Scott's fellow Australian Jason Day, who carded a four-over 74 to drop from a share of the lead to even par for the tournament.
Alongside Scott, Rory McIlroy also gave the leaders an early scare as he shot six birdies on his opening 13 holes, although two late bogeys saw the world number one drop off the pace slightly and complete the U.S. Open at even par overall.
