Wong Kam-po lost ground on the leaders in the Centennial Tour of the Philippines yesterday as his bid to retain his title took a beating at the halfway mark of the 16-stage race. Having gained almost three minutes after the seventh stage on Thursday, Wong needed a good performance to boost his hopes of making further inroads. Instead, he lost three minutes and 48 seconds to the leaders after a poor effort in yesterday's 148.5-kilometre stage. Wong paid the price for closely guarding his rivals, coming home seven minutes and 24 seconds behind stage winner Enrique Domingo of the Philippines. Wong kept Filipino rider Victor Espiritu and China's Tang Xuezhong in his sights throughout the race and finished in 46th place behind Tang and Espiritu. But Wong was still in a defiant mood saying he still had a chance of winning the race. 'My performance over the past two days has definitely improved. I have lost a lot of time in the early stages but I hope to gain some of this back in the following mountain stages. I'm feeling good.' Wong currently lies in 22nd place - 35 minutes and 54 seconds behind Tour leader Warren Davadilla. The Tour takes a rest today before resuming with a two-part stage nine inside the Subic Bay Freeport Circuit with a 20.1 kms individual time trial and a 80.4 kms criterium. It will then proceed to Northern Luzon and the decisive Baguio stages 12 to 14 with significant mountain climbs. While Davadilla was hanging on to his 53-second lead, the Philippines were parading another stage winner. The 28-year-old Domingo nipped Placido Valdez of Nueva Ecija for first place with Malaysian Nor Effandy Rosli finishing third in the stage which ended at the famous Subic Bay. Domingo, last year's sprint champion, clocked three hours, 29 minutes and 33 seconds and moved within 14:19 of teammate Davadilla while holding on to seventh position in the overall standings. It was the sixth stage win in eight days for the Philippines, who continued to pull away in the team rankings. They increased their advantage over Pangasinan (a Philippine regional team) to 25:21, and over Malaysia by 38:02.
