Adam Scott shot a 3-under-par 68 to win his third Singapore Open by three strokes, completing his final 10 holes Monday after a lengthy thunderstorm suspension Sunday.
Scott, who won at the Sentosa Golf Club in 2005 and 2006, had a 72-hole total of 17-under-par 267.
Anders Hansen of Denmark shot 68 to finish second, and Sweden's Rikard Karlberg (67) and U.S. Open champion Graeme McDowell of Northern Ireland (70) were tied for third, four shots behind Scott.
Scott took over the lead in the second round, opening with rounds of 65 and a 69. On Monday, he three-putted the 14th for a bogey, but finished with a birdie from 12 feet on 18 to win his seventh European tour title and first in 2 1/2 years.
"It feels great," Scott said. "Relief to finally get finished, it's been a bit of a long week.
"I haven't been putting my best lately and the demons started creeping in on the back nine. But it's a course I absolutely love and I've played so many great shots here."
Hansen, who has won two European tour events, missed a 20-foot birdie putt on the 15th hole.
"If I had holed that one, I would only be one behind with three to go and then you never know," Hansen said. "But I missed it so the chance was gone."
Play was suspended for 5 1/2 hours Sunday, forcing the Monday finish. The opening round Thursday had a four-hour weather suspension.
U.S. Masters champion Phil Mickelson had a final-round 70 to finish on 3-under. His final-round score included a two-stroke penalty invoked by the European Tour for showing up late at the course from his hotel for the resumption of play Sunday afternoon.
Defending champion Ian Poulter and South Korea's Kang Kyung-nam trailed Scott by a stroke after three rounds, but both fell off the pace in the final round. Kang finished fifth after a 72 and Poulter had a 73 to finish tied for sixth with James Donaldson of Wales (70).
