Lee Lai-shan's imperious march to a gold medal in the windsurfing event was halted by mother nature. The 32-year-old Hong Kong ace has dominated her opponents here, but heavy rain that enveloped the Bay of Pusan yesterday resulted in her putting on hold her bid to wrap up the series. Organisers were forced to postpone races seven and eight yesterday due to the poor conditions. A fog-like mist and driving rain reduced visibility resulting in the two races being re-scheduled for today which was originally supposed to be a rest day. A number of other outdoor sporting events, from baseball to tennis, were also cancelled. The weather is also a worry with the showpiece track and field events in athletics due to start today. San San leads the field having won five of the six races held so far. In the other she finished second. Having to discard one result after six races, San San dropped her second place finish to currently hold a net aggregate of five. She leads second-placed Japan's Masako Imai by seven points while China's Yin Jian is third, eight points adrift. San San enforced her domination on Saturday when she won all three races to take an almost impregnable lead. But coach Rene Appel was not counting the medal before it is mathematically assured. 'San San will need to win the next three races before she is certain of winning the gold,' said Appel after San San's hat-trick of wins on Saturday. On her current form, however, the 1996 Olympic Gold medallist, looks a certainty to win her second successive Asian Games gold medal. While things are looking up on the high seas, in the lanes the SAR is struggling to find the right lines, thus dimming the prospect of a medal. Hong Kong's women tenpin bowlers threw away a great opportunity to win a bronze medal yesterday when they choked in the trios event. In third place with two games left, Hong Kong's Jenny Ho Long-mui and Janet Lam-yim failed to provide the support for third member Vanessa Fung Suet-yee as they faltered to finish in sixth position. Fung played brilliantly and finished the day with an average of 223.67 points, the highest in the 48-strong field from 16 countries. But it was a lone battle as the left-handed Ho and Lam shot a dismal 165 each in consecutive games. 'I tried my best to lift their spirits. I told them jokes and made fun with them, trying to get them to relax. But it is hard for a third party to change things. It all depends on you. But we gave it our best shot,' said Fung. Hosts Korea won gold, while the silver went to Taiwan and Malaysia took bronze. While disappointed at missing out on a medal, Hong Kong's Venezuelan technical coach Rubens Ghiragossian was not totally downcast. 'There was nothing wrong with the way they bowled. We were beaten by better teams. The girls exceeded all expectations,' he said. But there was no consoling Lam. 'It is really disappointing. If we had won the medal it would have been our first medal in bowling and that would have relieved the pressure on us to win,' said Lam. Hong Kong's best hopes of a medal now remain with Lam and Fung, who are both on target to qualify for the Masters competition. Defending champion in the men's Masters event, Sunny Hui Cheung-kwok, meanwhile, is struggling to qualify for the elite competition where individual scores in all the other events - singles, doubles, trios and team fives - count. Only the top 16 competitors will take part in the Masters with each country allowed to field a maximum of two players. 'We will be going all out to do well in the Masters,' said Fung. Her mother, vice-president of the Hong Kong Olympic Committee, Vivien Fung, will be praying for that.
