Rory McIlroy fired a third round 65 to open up a three stroke lead over American Anthony Kim at the Lake Malaren Shanghai Masters.
Northern Ireland's US Open Champion, trying to complete a wire-to-wire victory just as he did for his first Major title in June, ended the day on 18 under par.
McIlroy did not drop a stroke and turned in 32 with birdies at the first, third, seventh and ninth - the hole he double-bogeyed in his second round 69. The 22 year old World Number Three then picked up more shots at the 13th 15th and 16th.
Kim, who failed to retain his Ryder Cup place last year after undergoing thumb surgery, matched McIlroy's round, but made his final day task all the tougher by finishing with a bogey.
Twenty year old Korean Noh Seung-yul is in third place, but a 67 left him four back and there is then a further three stroke gap to England's Ian Poulter, also round in 67.
World Number Two Lee Westwood produced only a 70 and, alongside Australian Geoff Ogilvy in sixth place, is now 11 adrift.
