JAKARTA: Lee Westwood celebrated his 38th birthday with a comfortable three-stroke victory at the Indonesian Masters Sunday to stay in the hunt for regaining the world No. 1 spot from German Martin Kaymer. The world No. 2 will top the rankings if fellow Briton Luke Donald, who leads by a stroke at the $750,000 Heritage tournament in South Carolina after the penultimate round, fails to land the trophy. “It was about coming here this week and trying to win the Indonesian Masters and I've done that. I've ticked every box this week so we will have to wait and see what happens,” Westwood said after his win. Donald could overtake Kaymer, who is not playing this week, and Westwood, despite his victory, because the Heritage carries more ranking points than the Asian Tour event. Westwood, who was world number one for 17 weeks until Kaymer replaced him in February, birdied the 11th and 12th holes after eight straight pars to take control of the leaderboard to end at 19-under 269. Thailand's Thongchai Jaidee finished second with a bogey-free 65 while Park Hyun-bin of South Korea and Thailand's Thitiphun Chuayprakong were joint third along with Bangladesh's Siddikur Rahman and Australian Marcus Both at 13-under 275. Donald well set Luke Donald recovered from a faltering start to remain one shot clear after The Heritage third roundat Hilton Head Island Saturday, staying on track to become world number one for the first time. Briton Donald, who will take over at the top of the rankings if he triumphs at Harbour Town Golf Links on Sunday, fired a one-under-par 70 for an 11-under total of 202. Jim Furyk, who won last year's title in a playoff, was second after carding a 69, one shot in front of fellow American Scott Verplank (67) and Zimbabwe's Brendon de Jonge (66). Englishman Donald, a stroke ahead overnight, double-bogeyed the par-five second after hitting his tee shot out of bounds but fought back on a blustery afternoon to retain control of the PGA Tour event. “It was tougher today, the wind was more of a factor and the greens are getting firmer and crustier,” Donald told reporters. “And I was pleased with bringing it back after that slow start.” Furyk had been tied for the lead with Donald playing the last but his second shot bounced over the green into a bunker from where he failed to get up and down to avoid a bogey. Donald, who claimed his maiden PGA Tour victory at the WGC-Accenture Match Play Championship in February, is bidding to become the fourth world number one in less than six months. He will leapfrog top-ranked Martin Kaymer, who is not playing this week, and No. 2 Lee Westwood even if the latter wins the Indonesian Masters because the Heritage carries more ranking points than the Asian Tour event. Colsaerts wins in China Nicolas Colsaerts set a tournament record at the China Open Sunday, totaling 24-under to win by four shots from a group of four players. The Belgian, who only regained his European Tour card last year, made six birdies in a 6-under 66 to total 264 and beat the old mark by five strokes. The previous record was held by Prayad Marksaeng of Thailand and Ed Fryatt of England, who both totaled 19 under to win the tournament in 1996 and 1998, respectively. Colsaerts is only the second Belgian to win on the European Tour, after Philippe Toussaint's victory at the Benson and Hedges International in 1974. Pablo Martin of Spain (63), Peter Lawrie of Ireland (68), Soren Kjeldsen of Denmark (66) and Danny Lee of New Zealand (65) were next at Luxehills International Country Club in the southwestern city of Chengdu. Former Ryder Cup star Sergio Garcia (69) was at 274.
