Felipe Aguilar produced a breathtaking back nine to take the Championship title at Laguna National in Singapore.
Aguilar began the day four shots off the pace and made two birdies in his opening nine holes before his round came to life after the turn.
The Chilean recorded a further six birdies but it was his eagle on the last that took him to 22 under par overall and a one-shot victory from American David Lipsky and Anders Hansen, of Denmark.
“Yesterday I thought I had no chance,” Aguilar said. “Today I said to my caddie on the 17th, after I made a birdie, a birdie on 18 would put some pressure on the leader. He said we should make a 2.
“I said to him the way I had been hitting the ball I could well do. It’s a long story but I made 2 on 18, and what a beautiful way to finish.”
Aguilar came home in 28 to record a 10-under-par final round and seal his second victory on the European Tour, with his other success coming in the Enjoy Jakarta Astro Indonesia Open in February 2008.
Lipsky can feel aggrieved to finish runner-up after carding a bogey-free 65, while Hansen, who was joint overnight leader, recorded a five-under-par round for the third time this week.
