HUA HIN (Thailand) (AFP) - Japan's Tetsuji Hiratsuka claimed his third title of the season Sunday when he won the 600,000-dollar Black Mountain Masters after a play-off against Thai youngster Namchoak Tantipokakul. Hiratsuka triumphed in the Asian Tour's season-finale at the Black Mountain Golf Club with a par at the first play-off hole on the par-five 18th to pip Namchoak, who bogeyed in extra time. The Japanese veteran, who also won the Air Bagan Myanmar Open and Queen's Cup in Thailand earlier this season. , signed off with a one-under-par 71 and was caught by a fast-charging Namchoak, who ended with a 65 for a 14-under-par 274 in a thrilling end to the season. "After I missed a putt (to win in regulation), I knew I still had a chance in the play-off," said the 39-year-old Hiratsuka, whose 95,100-dollar cheque saw him end the season in fifth place on the final Order of Merit. "There were no easy putts out there, even when the putts were short. I tried hard every day. I love the Asian Tour and now I want to concentrate on improving my world ranking and break into the top-50," added Hiratsuka, who was ranked 82nd entering the Black Mountain Masters. Namchoak didn't quite live up to his nickname of "Lucky" despite a stunning final round which included seven birdies against no bogeys. The 23-year-old found some consolation, however, as his 65,100-dollar cheque has helped him to earn his Asian Tour card for next season, with the Thai finishing 35th on the merit list. Overnight leader Piya Swangarunporn was dealt a double blow when he missed out on the play-off by one shot after closing with a 73 to discover he had missed his Tour card by a mere 205 dollars. It was also heartbreak for Lee Sung of South Korea, who bogeyed his last hole to finish one shot shy of the play-off in his round of 70. Thai star Thongchai Jaidee, who was in the thick of battle, fell off the pace with a double bogey, bogey, bogey run from the 11th hole to eventually finish seventh, two shots back.
