JEJU ISLAND  - Kim Bi-O held his nerve to secure a second OneAsia victory in a row and leap to the top of the Order of Merit with a three-shot victory in the SK Telecom Open on Sunday.

The 21-year-old home favourite fired rounds of 68-68-67-67 for an 18-under-par total 270 around Pinx Golf Club on the South Korean holiday island of Jeju, beating compatriot Park Sang-Hyun into sole second place. Kim took home a winners cheque of about $170,000, bringing his earnings on OneAsia to nearly $250,000 in 2012.

It was his third OneAsia title following a five-shot triumph in last week’s GS Caltex Maekyung Open and a play-off victory at last year’s Nanshan China Masters. Kim had seen his two-stroke overnight lead evaporate when Park, playing in the group ahead, scored three birdies and an eagle on his first four holes. He made the turn in just 30 and then eagled the 10th to move two strokes clear. The tide turned back in Kim’s favour in a half-hour spell over the closing holes. After making birdie on the 14th, he hit an aggressive second shot on the par-five 16th behind a thick clump of grass, in deep rough.
