New Zealand's Michael Campbell is the surprise winner of the 105th US Open at Pinehurst.
The Kiwi bogeyed the last to slip back to level par but still won by two shots from Tiger Woods, who mounted a trademark final-day challenge.
Overnight leader and defending champion Retief Goosen experienced a torrid fourth round, carding an 81.
Sergio Garcia, Tim Clark and Mark Hensby finished on five over in a tie for third.
All the action from Pinehurst (all times BST):
2348: The final group of Retief Goosen and Jason Gore reach the last to complete what has been a miserable day for both men.
Goosen, in particular, will be shell-shocked after an 11-over 81. Gore carded an 84 that ended with a double bogey but was still smiling when he left the 18th green.
2340: Michael Campbell has three putts to win the US Open...and he needs two. A bogey finish but the European Tour player will not mind. Ten years after blowing a 54-hole lead at the Open, Campbell is a major champion.
Tiger Woods' caddie Steve Williams, a fellow New Zealander, is one of the first to congratulate Campbell.
2338: Michael Campbell does not want to finish with a bogey...and he should not have to after pitching his third to within four feet of the flag.
He is now certain to become only the second Kiwi to win a major (after Bob Charles' Open victory in 1963).
2336: Michael Campbell finds the bermuda grass with his drive so he elects to lay up short of the greenside bunker with his second. A bogey-finish is now likely, but with three shots to play with he should be OK.
2329: Michael Campbell's grip on the 105th US Open just got much tighter. Only a minute after Tiger Woods increased the pressure on the Kiwi with a trademark birdie at the last, Campbell hit back with a superb two at the 17th to get to one under, three shots clear.
2321: Tiger Woods is not one to go quietly. A massive drive at the last leaves him with just a sand wedge to the green. He puts that to within 15 feet of the pin for a birdie chance.
Michael Campbell, however, carries on regardless with a solid par at the 16th.
2313: Shortly after Michael Campbell's brave up-and-down at the 15th, Tiger Woods three-putts the 17th to return to three over. Is that the moment the New Zealander clinched his first major title?
Up ahead, meanwhile, Lee Westwood completes a disappointing final round of 79. In freefall after a double bogey at the second, the Englishman finishes at 12 over for the tournament.
