Hong Kong teenage sensation Wu Siu-hong solidified his Asian number-one ranking by winning the men's open masters event at the Mahatrako International in Jakarta at the weekend. Wu, who took a year off his studies to become a full-time player, won US$5,000 for his efforts in his second outstanding result of the year. The 17-year-old Form Four student had earlier finished second at the prestigious CGU Asian Bowling Tour grand slam in Singapore, and he got 2002 off to a winning note by beating a strong amateur field in the Indonesian capital. Averaging 226 for a 3,617 total pinfall, Wu easily won the event with 71 points to spare from Malaysia's Ricky Chen, who finished second with 3,546 points. Indonesia's Ryan Lalisang finished third another 38 points behind. Wu had earlier won the men's open event in Jakarta with a total pinfall of 1,838 that enabled him to qualify for the 30-strong masters event. 'The field wasn't so strong in Jakarta so it wasn't such a big win for me. I think finishing second in Singapore was a bigger achievement. Most of the top bowlers from Asia competed in Singapore so it was good to see where I stood against them. Finishing second was an encouraging result. 'But it is good to win the Jakarta event and this gives me confidence for my other events this year,' said Wu, one of the favourites for gold at this year's Asian Games in Pusan. Wu won two gold medals at last year's East Asian Games in Japan - the masters and doubles with Sunny Hui Cheung-kwok - and has gained a reputation as one of the finest bowlers in Asia.
