Helped by an ace on the par-three 16th hole, Quincy Quek from Singapore came from behind to capture the ICTSI Orchard Golf Championship in the Philippines.
The 25-year-old carded rounds of 69-68-74-65 to secure his first career win on the Asian Development Tour (ADT).
Long regarded as a rising talent in Singapore, Quek won five titles during his illustrious amateur career.
This first win as a professional will be help him regain his momentum after a suffering set-backs from injuries in 2010 and 2011.
Quek's last win as an amateur was also in the Philippines back in 2009.
"I just wanted to put in a good score as it was my last day in the Philippines and I thought I could shoot a good final round," said Quek, who pocketed the winner's prize cheque of US$10,500 (S$13,200).
"It didn't occur to me it could be a possibility to win at this stage, so it did come as a surprise.
"I didn't know where I was standing until I got to the 16th hole where there was a leaderboard.
"For the hole-in-one on the 16th, I hit it well with a slight draw and saw it land on the green, about 10 feet away from the hole.
"When it disappeared into the hole, the cameramen and caddies jumped to their feet in excitement. From that moment on, I took the lead for good and managed to hold on for a win."
Quek now sits in tenth place on the ADT Order of Merit and gives him a chance to finish in the top 3 at the end of the season to earn playing rights on the Asian Tour next season.
