Singapore's Lam Chih Bing held his nerve in a tense final round to shoot a five-under 67 and win the Volvo Masters of Asia on Sunday. Lam carded five birdies on a blemish-free round to finish 14 under par and seal victory the Asian Tour's season-ending championship, two strokes ahead of Thai Chapchai Nirat, with Australian Terry Pilkadaris third on 11-under. Lam shared the overnight lead with four other players going into a thrilling final day and surged away from the pack with three decisive birdies in the last four holes. Chapchai's bid to become the third Thai in succession to win the season-ender was derailed in the first six holes, where he had a frustrating three bogeys and a double bogey. The big-hitter later admitted he was playing with an injured shoulder but fought through the pain to land five birdies on the back nine, finishing on 69 for second place on 12-under. Thai Chawalit Plaphol hit a 73 and Australia's Marcus Both a grim 75, while compatriot David Gleeson carded a 71 having thrust himself into contention with a course record-equalling 63 on Saturday. Sterne wins SA Open In South Africa, Richard Sterne claimed his second successive tournament victory on home soil when he edged out Britain's Gareth Maybin in a playoff to win the South Africa Open on Sunday. Sterne finished level with Maybin on 14 under par but birdied the first extra hole to become the event's eighth consecutive home winner. It was the South African's fifth European Tour victory and third of 2008 after he won the Johannesburg Open in January. “I was pretty confident playing the first again because I'd birdied it twice before so I had a good feeling for it,” Sterne told reporters. Kim seizes lead In California, US Ryder Cup star Anthony Kim fired a 5-under-par 67 Saturday to seize the third-round lead at the $5.75 million Chevron World Challenge. Kim's 67 matched Vijay Singh for the low round of the day and gave him an 8-under total of 208. He also benefitted from a late mistake by overnight leader Jim Furyk, who took a double-bogey at the last en route to a 70 for 209. Colombian Camilo Villegas, Steve Stricker, and Fiji's Singh were two shots off the pace in the tournament, which is hosted by Tiger Woods for the benefit of his charitable foundation.
