Louis Oosthuizen wins Volvo Golf Champions with impressive come back in Durban "What a great week for me," said Oosthuizen. Yesterday was tough as I finished two over, but today was fantastic. My third round troubles stemmed from a problem with my swing which I could not fix on the course. I concentrated today on a shorter, tighter swing and it paid off. It was the sixth success on the European circuit for the 2010 British Open champion and victory in perfect summer conditions lifted him two places to fourth on the world rankings. The 30 year-old from Mossel Bay in the western Cape birdied four holes on the front nine and another three coming back before dropping a stroke on the par-four 16th, where he misread and pushed a short putt. Pars at the final two holes sealed success and the £1.67 million prize money despite Jamieson's narrow miss on the last. Jamieson started his final 18 holes promisingly with birdies at three and four only to double bogey the par-four fifth and turn in a level 36, leaving him a solitary stroke ahead of Oosthuizen. After six consecutive second-nine pars, he bogeyed 16, parred 17 and birdied 18 to end with a level-par 72 while Thongchai carded a 68, Harrington a 68, Quesne a 71 and Willett a 68. Grace, winner of five European titles last season, was always playing catch-up after an opening 75 and although he closed impressively with a five-under 67, ended six strokes behind Oosthuizen.
