Fiji's Vijay Singh won the US850,000 dollars Singapore Masters with a score of 21 under par 263 today while Padraig Harrington finished tied for fifth with Denmark's Anders Hansen at 17 under par 267.
Harrington had earlier called a one-shot penalty on himself on the 16th hole.
The Irishman, who lost out in a play-off to Singh in Kuala Lumpur, was addressing his second shot to the par four 16th when the ball moved a fraction of an inch. The Ryder Cup player instantly turned away in disbelief knowing it would cost him a one-shot penalty and end his fading chances of victory.
Rules officials were called to confirm what Harrington already knew and after replacing the ball in its original position, the 29-year-old Dubliner played his third shot to the green and missed from 25 feet to save par.
Singh, the winner of the Malaysian Open last week in a play-off, led all the way through the final day to ensure victory by two strokes over England's Warren Bennett who finished at 19 under par 265.
Colin Montgomerie of Scotland was tied for third place with Maarten Lafeber of The Netherlands at 18 under par 266. AFP
