Two-time reigning Olympic champion Lin Dan came from behind to overcome Chinese Taipei’s Chou Tien-chen in the men’s singles final at the Badminton World Federation (BWF) German Open in Mülheim an der Ruhr today.

The Chinese number two seed lost the first game 15-21 against his fourth-ranked opponent but recovered to take the second and third games 21-17.

Lin’s compatriot Li Xuerui claimed the women’s singles title after defeating fellow countrywoman Wang Shixian in straight games. 

The London 2012 gold medallist took just 36 minutes to register a 21-14, 21-17 victory against the number four seed as she continued preparations for the defence of her Olympic crown in impressive fashion.

There was further success for China in the women’s doubles final as Huang Yaqiong and Tang Jinhua overcame Thailand’s Puttita Supajirakul and Sapsiree Taerattanachai 21-14, 21-18.

South Korea’s Ko Sung-hyun was the biggest winner of the day, taking the men’s doubles title alongside Shin Baek-cheol who he earlier beat to the mixed doubles crown with partner Kim Ha-na.

Seeded number six, Ko and Shin defied the odds to beat fellow South Koreans Lee Yong Dae and Yoo Yeon Seong, the top seeded men's doubles pairing, 20-22, 21-18, 21-17.

Ko and Kim justified their number one ranking in the mixed doubles by downing Shin and his South Korean team-mate Chae Yoo-jung, 21-19, 21-12.

The German Open is a BWF Gold Grand Prix event.
