Wong Kam-po's chances of defending the Tour of the Philippines title are slipping away after his disappointing finish in yesterday's difficult 226.2-kilometre fourth stage.
Wong finished 28th in the stage that featured a long uphill climb to a mountain park in Quezon province, 116 kms into the race, with a time of six hours, four minutes and 59 seconds.
The China National Game gold medalist is now 29th overall with a time of 18 hours, 42 minutes and 40 seconds - 33 minutes and 59 seconds behind leader Warren Davadilla of the Philippines.
Another Hong Kong rider Man Wai-chung finished 33rd yesterday in the same peloton as Wong and China's Pan Guangcun and Tang Xuezhong.
Hong Kong's Ho Siu-lun finished 63rd and Ng Kwok-wah 67th.
Man is currently 22nd overall with a time of 18 hours, 39 minutes and 10 seconds.
Davadilla, who wrested the leader's yellow jersey from teammate Arnel Quirimit after the second stage, humbled his three breakaway partners in the sprint for home to clinch his first stage victory in a three-year career.
