Hong Kong won only its second-ever gold medal at the fifth National Intercity Games in Changsha, Hunan when tennis player Brian Hung Lap-hei shocked the No1 seed in the men's singles final on Monday. The Hong Kong junior No1 was unseeded, yet powered to an easy 6-0, 6-2 win over title favourite Gao Peng of Beijing on the final day of the Games. On route to the final Hung, 18, beat other seeded players including Li Jian of Guangzhou (8), Xue Feng from Nanjing (4), and Yin Xu (2) in the semi-finals. 'I was at my best at the right time,' said Brian. 'Before the final, the general consensus was that he [Gao] was the best player - but I was ready for him and I put him under pressure.' Hong Kong Tennis Association coach Hu Bing, who accompanied Hung to the competition, said the teenager utilised a strong forecourt game to perfection. 'His persistent net attacks rattled his opponent and forced him into mistakes,' said Hu. Hung, who became a full-time athlete two years ago but now studies on a tennis scholarship at the University of Michigan, finished fourth in the doubles with Jack Hui Cheuk-wai. Thousands of under-23 athletes from more than 78 cities, special economic zones and municipalities took part in the 10-day mega-event. With two golds and one bronze, the SAR beat its previous efforts in Xian four years ago when it took one silver and one bronze. The other medal winners in Changsha were cyclist Lam Kai-chun, who won Hong Kong's first inter-city games gold in the men's road race, and windsurfer Chan Wai-man, who won bronze in the women's mistral. Hong Kong sent 89 athletes who competed in 14 sports - swimming, diving, athletics, badminton, gymnastics, shooting, table-tennis, baseball, cycling, fencing, rowing, windsurfing, tennis and wushu. The competition was a chance to spot talent and build team spirit ahead of next year's Olympics.
