Cabrera started the round with a four stroke lead at 9-under, but carded a one-over 72 in the final round of the event at Sentosa Golf Club.

Singh turned up the heat during the round by climbing up the leaderboard from six strokes off the pace to trail Cabrera by two shots after only seven holes at the remodeled 6,710-yards (6,130 meters), par-71 Serapong Course.

The Fijian's advance began with an eagle on the fourth hole, a dogleg-left par five that sweeps around a lake, and four birdies.

He later conceded two bogeys.

Singh missed an eagle putt from about 20 feet on the final hole, but birdied to go neck and neck with Cabrera at 7-under. The Argentine effortlessly shot a birdie on the same hole to seal his win.

Cabrera finished with a four-round total of 8-under 276, with Singh's four-under 67 in the final round gave him 277.

"It was really a very, very tough day, very windy. I didn't strike the ball my best in the beginning of the round," said Cabrera.

"But I worked very hard during the round and I got it together in the end and started hitting the ball very well in the last holes and I made it up," said Cabrera, who pocketed $634,000 in prizemoney.

"I knew that Vijay was putting together a good round and playing well. It was up to me to play well on the last two holes and I did that."

Singh said he was satisfied with the way he finished despite being one back. He took home $434,000.

"I'm playing against a guy who is the U.S. Open champion and you can't expect him to make too many mistakes," he said. "I played well, made some good putts on the front nine and putted well all day. Just came one short."

Two-time defending champion Adam Scott, ranked sixth in the world, shot four birdies and just as many bogeys to finish the round at even par, four strokes behind Singh in third place. Scott won $244,000.

"I missed a couple of greens and made bogeys and that seems to be how my year has gone," said Scott, of Australia, who had hoped a three-peat in Singapore will cure his disappointing form. The Houston Open has been the Australian's only victory this year.

"I've not scrambled well enough to keep myself going in tournaments which was a case of that today," Scott said.

World No. 2 Phil Mickelson, who had struggled in the previous round because of the tropical heat, slid even further with a triple bogey on the troublesome No. 3, and double bogeys on the seventh, thirteenth and sixteenth holes to finish with a 79.

"It's tough to get the balls close to the hole because they are not stopping on the greens too well," said Mickelson. "The fairways are very tight and the rough is up and so it's a very good test because it tests every element of your game."

American rookie Jin Park, who came into the round four strokes off the lead in second place, dropped a few notches when he carded four bogeys against just one birdie and finished fourth.

Lee Westwood finished fifth at 1-under after a 3-over 74 final round.

In sixth place at even par was Thailand's Prom Meesawat, a shot ahead of Japan's Tetsuji Hiratsuka.

K.J. Choi of South Korea made two birdies in the front nine but the World No. 9 fell behind when he carded three bogeys and a double bogey to finish in shared 14th place, 5-over.
