SINGAPORE - Four golfers were locked in a tight battle to win their first Asian Tour title, and Thailand's Danthai Boonma prevailed to win the World Classic Championship on Sunday.

Under windy conditions at Laguna National, the 19-year-old golfer proved more consistent than his rivals South Korean Wang Jeung Hun, overnight co-leader Nicholas Fung of Malaysia and first-round co-leader Australian Sam Brazel, posting a two-under 69 to close on two-under 282 overall.

After opening with seven pars, he made a bogey on the eighth hole which meant he was two strokes behind then-leaders Wang and Fung.

But the Thai roared back after the turn, firing three birdies on the 10th, 12th and 13th holes, which shot him to the top of the leaderboard, level with Fung on two under.

But Fung, who had been shooting consistently in the round, faltered on the 16th hole, where he missed a two-foot putt for par. The costly error dropped him to second spot, while Danthai kept his composure to claim par on his final five holes.

The Malaysian had a chance to force a play-off with Danthai but he failed to sink a nine-foot birdie putt on the 18th hole, handing Danthai his first victory since turning professional last December.

Fung carded a 72 for a 283 total, Wang (69, 284) took third spot and Brazel (70, 285) finished a further stroke behind.

The title is Danthai's second trophy won in Singapore, having collected the Singapore Open Amateur Championship last June.

Singapore's Choo Tze Huang, the only local golfer to qualify for the final two rounds, shot his best result of the four-day tournament. He signed for a level-par 71 to finish tied-20th on eight-over 292.

Overnight co-leader Siddikur Rahman of Bangladesh misfired badly. He spoilt his scorecard with an astonishing four double-bogeys and bogeys each to end on 11-over 82 (293), dropping him to tied-30th.
