JAKARTA, (Reuters) - Lee Westwood celebrated his 38th birthday with a comfortable three-stroke victory at the Indonesian Masters on Sunday to stay in the hunt for regaining the world number one spot from German Martin Kaymer.
The world number two will top the rankings if fellow Briton Luke Donald, who lead by a stroke at the $750,000 Heritage tournament in South Carolina after the penultimate round, fails to land the trophy.
The Englishman, who lead by five strokes after the third round, started with a birdie on the first hole but dropped a shot on the second to make the turn at even-par 36 at the Royale Jakarta Golf Club.
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 brilliant bogey-free round of 65 while Park Hyun-bin of South Korea and Thailand's Thitiphun Chuayprakong were joint third alongwith Bangladesh's Siddikur Rahman and Australian Marcus Both at 13-under 275.
