Barring a major mishap, overall leader Wong Kam-po should capture his fourth Tour of South China Sea title today when he crosses the finish line at Macau Jockey Club Square, according to his longtime coach Shen Jinkang. Shen made the prediction after Asian Games champion Wong retained his yellow jersey and an 18-second lead over his nearest rival, Neil MacDonald of South Africa, despite Wong's failure to win yesterday's gruelling hilly stage - a 90km road race around Coloane. Both Wong and defending champion MacDonald were 27 seconds off the pace of mainlander Wang Guozhang, who clocked two hours nine minutes and 36 seconds to win the stage. Wong kept his eyes on MacDonald throughout the race before finishing 26th, three places behind the South African. Shen said: 'Unless something dramatic happens, Wong would be able to win the Tour because tomorrow's stage [66km criterium] will be raced over a flat course and the strength of the Hong Kong team overall on flat surfaces is strong.' If past records are anything to go by, Wong should claim his fourth title - after successes in 1996, 1997 and 1999 - because in past the overall leaders going into the final stage have never failed to win the Tour. But Shen pointed out it would be dangerous if Wong, who raced conservatively in the past two stages in Zhuhai and Macau after racking up three straight wins - in Tsing Yi, Shenzhen and Zhongshan - does not take the initiative and attack. 'It's fortunate that he didn't lose his yellow jersey today. He shouldn't have stayed back and reacted to others' moves most of the race. He must keep focused and be aggressive because he'll waste plenty of energy chasing others,' Shen said. Wong explained he failed to attack yesterday because he was regularly targeted by his rivals and received limited support from his teammates. 'I'll aim to retain my yellow jersey and, therefore, win the Tour but I'll also try to win the stage to end the Tour perfectly. 'Today's stage was tough because my teammates weren't particularly strong in mountain-climbing. Having said that, I found this stage not as hard as before because they have improved a lot and supported me better,' Wong said. National teammate Tsang Kai-ming was among the leading pack in the first five laps of the 10-lap race and helped keep the leading riders at bay while allowing Wong to concentrate on containing other title contenders. Japanese Masahiko Mifune overtook South African Jeremy Maartens as third overall after sprinting to second in yesterday's stage to sit 34 seconds behind Wong's overall time.
