Hong Kong's Wong Kam-po retained fourth place overall in the Tour of Taiwan after two stages yesterday - but failed to make ground on the leaders. Wong, who is looking to regain the Tour after winning the event in 1996, finished eighth in the fourth leg - a 90-kilometre road race from Chiayi to Alin - and then shared the same time as the race leaders in the fifth leg - a 60-kilometre criterium in Kaoshiung. Wong, however, failed to put pressure on overall leader Tsen Seong Hoong of Malaysia. The Hong Kong rider is now two minutes, 25 seconds behind Tsen but with three more stages to go, he has a chance of bridging the gap. He was less than two minutes behind Tsen going into the fourth leg after winning the tough third stage on Tuesday. The fourth stage was won by American Brian Whitson in two hours, 24 minutes and five seconds in a blanket finish. Malaysian rider M. Kumaresan was second with Taiwan's Chen Keng-hsien third. Wong finished with the leading pack - a fair result considering that he is not a noted rider in criteriums and prefers tough, uphill climbs. The fifth stage was won by the United States' Derek Wilkerson in 1:19.30 with another American, Cameron Hoffman, in second place sharing the same time. Kumaresan showed his consistency by taking third spot. Wong, who finished second in the Tour last year and has been the top Asian rider in the Tour for four straight years, won the third stage after relishing uphill conditions in the last 30-kilometres of the race. That performance improved his overall position to fourth from 12th overnight. The Hong Kong number one rider, who is a genuine gold medal prospect in December's Asian Games, defeated a strong field to take out the 160-kilometre third stage from Tai Chung to Ali Shan. With some mountain stages left in the eight-stage Tour, the 25-year-old Wong could snatch the overall lead as he usually leaves his best work for last. The Hong Kong team are third overall in the team classification list while the Hong Kong CMS team are 11th overall.
