HONG KONG'S Wong Kam-po maintained a six-second overall lead in the Tour of Taiwan series despite finishing 30th in the fifth stage - the 75-kilometre criterium race - in the southern port of Kaohsiung yesterday. The Hong Kong camp were given a pleasant surprise on Wednesday evening when corrected results on the fourth leg showed Wong taking the race leader's yellow jersey from Alexandre Charapov of Belarus. That made him the first Chinese to wear the yellow jersey in the seven-year history of the tour that has been dominated by Europeans and Australians. Wong was never in any danger of losing his six seconds lead in the criterium race as the whole field virtually finished together, and he had the same time as stage winner Rolf Schmidt. The Germany Merida rider clocked 1:41:47 and filling the minor placings were Baden Burke of Australia Giant and Georg Weigenand, also of Germany Merida. 'Wong was playing it safe and did not join in the sprint because it would be good enough to conserve his overall lead just by keeping up with the leading pack,' said Walter Yue Ka-lok, senior sports executive of the Hong Kong Cycling Association. 'But he is in a very dangerous position because there are two Belarussians and three Germans breathing down his neck. Our team strategy now is for every member of the squad to help Wong chase if the other riders attempt a breakaway.' Hong Kong's Man Wai-chung and Tong Wai-bun finished in the second group yesterday in 45th and 54th positions with identical times of 1:41:58 while John Prosser was in the next group only five seconds adrift.
