HONG KONG - Two-time Olympic champion Viktor Axelsen of Denmark beat Chou Tien-xhen of Chinese Taipei to reach the semifinals of the Hong Kong Open badminton championships on Friday.
Axelsen, playing his first tournament after retaining his Olympic crown in Paris, trailed 4-6 early on but soon proved too good for the sixth-seeded Chou, winning 21-15, 21-14 after 48 minutes.
The Dane extended his head-to-head record against Chou to 19 wins and four defeats. He will next play Indonesia's Anthony Sinisuka Ginting, who triumphed 21-17, 14-21, 21-18 over local player Jason Gunawan.
The other men's singles semifinal will be played between China's Lei Lanxi and defending champion Jonatan Christie of Indonesia.
Lei edged Lee Cheuk-yiu of Hong Kong, China while Christie saw off Kodai Naraoka in a similar three-game thriller.
On the women's side, third seed Han Yue of China rallied past Japanese Aya Ohori 17-21, 21-9, 21-15, setting up a semifinal showdown against Pornpawee Chochuwong, who shocked sixth seed Busanan Ongbamrungphan in an all-Thai affair.
