But it was the bunker shot to three feet that won it for the young emerging golf star, probably the best of his life he explained afterwards.
It was a case of third time lucky for Rory McIlroy who had previously lost in play-offs at the European Masters and Hong Kong Open, and fans were worried for a while as a string of birdies were followed by bogies approaching the last, opening the door to Justin Rose. It really is hard to win for the first time on such a competitive tour.
Rory finished ahead of Henrik Stenson, who came third and Martin Kaymer, Paul Casey and Robert Karlsson who tied for fourth. Miguel Angel Jimenez finished joint-seventh ahead of Sergio Garcia, while the new Ryder Cup captain Colin Montgomerie was 13th alongside Alvaro Quiros and Ross Fisher.
Rory McIlroy can now hopefully forge ahead, having just the youngest ever golfer to break the top 20 in world golf rankings.
