Prayad Marksaeng of Thailand has shot a four-under 67 in the final round to win the Singapore Open by one shot, leaving Australia's Adam Scott in a tie for ninth.
World No.7 Scott had a round to forget as he signed off with a three-over 74.
He took a one-shot lead into the final round.
Marksaeng's victory clinched a place in the British Open in the process.
Phachara Khongwatmai of Thailand, Young-han Song of South Korea and Jbe Kruger of South Africa tied for second place at Sentosa Golf Club.
They also secured their places at the British Open, which takes place at Royal Birkdale from July 19-23.
The 50-year-old Marksaeng, who finished on nine-under-par 275 overall, had to wait two hours after completing his final round before he could celebrate victory.
