Lee Westwood won the Indonesian Masters on Sunday and ended up regaining the No. 1 spot in the world when Luke Donald lost a playoff in the PGA Tour event in South Carolina.
Donald would have jumped from No. 3 to No. 1 with a victory, but lost to Brandt Snedeker on the second hole of a playoff in The Heritage at Hilton Head Island.
After waiting out a lightning delay on the final hole, Westwood finished off a 3-under 69 for a three-stroke victory over Thailand's Thongchai Jaidee.
The English star, ranked second behind Martin Kaymer entering the week, won on his 38th birthday.
Asked what he wanted for his birthday, Westwood replied, ''Something silver and shiny.''
As he stepped off the 18th green a portion of the gallery sang ''Happy Birthday.''
Westwood finished at 19-under 269 in the Asian Tour event at Royale Jakarta. He took a five-stroke lead into the final day after opening with rounds of 68, 66 and 66.
''It was quite a day, really,'' Westwood said. ''I knew it wasn't going to be easy with a five-shot lead. I'm experienced enough to know that patience is the key.
''I hit the ball great, but didn't hit the putts when it mattered.''
He did hole a tricky birdie putt on No. 11.
''It was probably the hardest putt I had all day. it was 15 feet with 3 feet of break,'' he said.
Jaidee shot a 65.
