Hong Kong's Olympic silver medallists Ko Lai-chak and Li Ching crushed Japanese duo Seiya Kishikawa and Rysuke Sakamoto to win the men's doubles title at the Taiwan Open. Ko and Li were in outstanding form as they defeated the Japanese in straight games - 11-7, 11-9, 11-6, 11-2 - and clinch the ninth ITTF Pro Tour men's doubles title of their careers. The SAR pair, who won a silver medal at the Athens Olympics last year, were given a harder time in the semi-finals when they were pushed all the way before beating Taiwan's Chiang Peng-lung and Chuan Chih-yuan 4-3. The victory by Ko and Li was Hong Kong's solitary success in the tournament and somewhat made up for the disappointing performances by Tie Yana and Zhang Rui, who were the top seeds in the women's doubles. Tie and Zhang fell at the semi-finals, beaten by Singapore's Sun Bei and Wang Yue Gu. In the women's singles competition, Zhang was ousted at the semi-final stage by Li Jiawei of Singapore. Hong Kong's other two representatives, Tie and Lau Sui-fei, were knocked out in the last 16, losing to Sun Beibei (Singapore) and Yuko Watanabe (Japan) respectively. Both lost narrowly by similar 4-3 scorelines. In the men's singles, Ko was beaten in the quarter-finals, losing to Austrian third seed Chen Weixing.
