Australian Adam Scott made a birdie from six feet on the third playoff hole Sunday to beat Ernie Els and retain his title at the rain-shortened Singapore Open.

Organizers shortened the US$3-million tournament to 54 holes after the fourth round was abandoned due to rain at the par-71, 7,169-yard, Sentosa Golf Club's Serapong course.

``I am very happy to defend a title for the first time,'' Scott said. ``I had a real fight on my hands with Ernie. I got off to a fast start and he didn't. He played some spectacular shots out there.''

``I hit a lot more fairways here than I normally do. I played a lot of good shots out there. My putting was good in spots.''

The playoff was based on third-round scores, which Scott and three-time major winner Els led by three strokes at eight-under 205.

Scott and Els had finished eight holes in the final round Sunday before play was suspended a second time because of rain. The pair were neck-and-neck after both making par on the first two holes of the playoff.

On the final playoff hole _ the par-5 No. 18 _ Els drove the ball into the rough, but chipped back onto the fairway before guiding the ball to about 24 feet from the pin. His first putt placed the ball within eight feet, but it was all over for the Big Easy when he missed his next attempt and bogeyed.

Scott teed off on the same hole with a drive over water that found the fairway nicely, and landed his second shot on the sloped and rough fringe of the green. A birdie putt from about six feet secured the Australian's win.

Before the final round was abandoned, Els and Scott had shared a three-stroke buffer on the leaderboard at 10-under, with the South African making an eagle and two birdies but conceding two bogeys. Scott was mistake-free with two birdies.

``In the playoff, I had my chances, man . . . It is disappointing,'' said Els, who last appeared in Singapore in 2003 at the Singapore Masters, where he blew a lead to China's Zhang Lianwei on the final few holes.

Australia's Brad Kennedy finished third, one stroke ahead of China's Liang Wen-chong. India's Shiv Kapur was fifth, while Anthony Kang of the United States and Thailand's Prom Meesawat were a stroke back in sixth.

England's Lee Westwood was eight strokes off the pace with a three-round total of 213, while Shingo Katayama of Japan was a stroke behind.

Rick Gibson, a B.C. native who now makes his home in Manila, was near the bottom of the leaderboard in a tie for 63rd after a third-round 6-over 77 left him at 12-over 225. Ahmad Bateman of Windsor, Ont., missed the cut Friday.
