HONG KONG — Former badminton world No. 1 Lee Chong Wei clinched the Hong Kong Open Sunday by defeating Olympic champion Chen Long 21-14, 21-19, defying expectations that the all-time great may be reaching his end.

China's Chen, who beat world No. 1 Viktor Axelsen of Denmark to win the China Open for a fourth time last week, was stunned by 35-year-old Malaysian Lee, whose world ranking has fallen as he approaches the latter stages of his career.

Lee's triumph came at a time when his old nemesis Lin Dan of China suffered defeats in the China Open and the quarterfinals in Hong Kong earlier this week.

In the women's singles world No. 1 Tai Tzu-ying of Taiwan stunned India's Pusarla V Sindhu 21-18, 21-18 as the young top seeds slogged it out in a 45-minute battle.

Olympic silver medalist Sindhu, 22, also lost out to the 23-year-old Taiwanese star in last year's Hong Kong Open.

China's Zheng Siwei and Huang Yaqiong took just 35 minutes to seal a 21-15, 21-13 victory over Danish shuttlers Mathias Christiansen and Christinna Pedersen in the mixed doubles final.

Marcus Fernaldi Gideon and Kevin Sanjaya Sukamuljo of Indonesia beat Mads Conrad-Petersen and Mads Pieler Kolding of Denmark 21-12, 21-18 in the men's doubles final.

Top seeded Chinese duo Chen Qingchen and Jia Yifan clawed their way back from a deficit in a battle lasting one hour and 10 minutes, defeating Indonesia's Greysia Polii and Apriyani Rahayu 14-21, 21-16, 21-15 in the women's doubles final. — AFP
