Konstantin Ponomarev kept the Russian flag flying as he won the second stage of the Tour of South China Sea in Shenzhen yesterday. The Moscow Dynamo cyclist broke away from the pack in the closing laps of the 88km circuit race in Longhua district with two other riders, Prajak Mahawong of the Siam Bara team and Marco Polo team's Jamsan Ulzii-Orshkih, and crossed the line first. All three were credited with a time of one hour, 53 minutes and 49 seconds. The yellow jersey went to Ponomarev, who is leading the general classification on 3:44:21, followed by Mahawong and Ponomarev's teammate, Andrey Klyuev, who won the opening stage. Hong Kong's Chan Chun-hing, a mountain-bike specialist, was fourth, four seconds off the pace. 'We wanted to give Chan a chance today as he is not a target for the rest of the field, but unfortunately he lacked a powerful sprint to catch the leaders,' Hong Kong coach Shen Jinkang said. 'I have already said the Moscow team are the biggest threat to us and they have now won the first two stages.' Hong Kong's Wu Kin-san won the tour last year and the SAR outfit came first in the team classification. Wong Kam-po, who came second in the opening stage, trailed in a disappointing 78th yesterday, but the Asian Games individual road-race champion was still fifth overall and held on to the blue jersey as the leading rider from greater China with an accumulated time of 3:44:31. Hong Kong teammate Chan is running seventh overall with a time of 3.44.35. The third stage continues today with another circuit race of 112 kilometres in Nansha port, Guangdong.
