Badminton: Controversial Chinese win China Open

Chinese women's doubles team Yu Yang and Wang Xiaoli won the China Open on Sunday in their first tournament together since being booted out of the Olympics in a playing-to-lose scandal that rocked the London Games.

The second-seeded pair bested No. 6 seeds Miyuki Maeda and Satoko Suetsuna 21-19, 14-7 after the Japanese duo retired from the match when Suetsuna indicated she could not continue due to pain in her back following a fall.

Yu called it a "good restart" for the pair.

"We have won many titles before, but we're extremely happy with this one. It is a huge boost to our confidence," China's Xinhua news agency quoted her as saying.

In women's singles, Chinese Olympic champion Li Xuerui beat Ratchanok Inthanon of Thailand 21-12, 21-9, while in the all Chinese men's singles final top-seed Chen Long edged compatriot Wang Zhengming 21-19, 21-18.

In men's doubles, top seeds Mathias Boe and Carsten Mogensen of Denmark beat Ko Sung-Hyun and Lee Yong-Dae of South Korea 21-15, 21-14.

Ko and Lee were newly matched after Lee's former partner retired following the Olympics.

Yu and Wang were were among eight players disqualified from the 2012 Olympics for attempting to drop round-robin games in a bid to secure a favourable quarter-final draw.

Yu said she would retire, but resumed playing for the Super Series Premier event in Shanghai, after being cleared by sporting authorities.

All the players involved in the Olympics scandal have been cleared to resume competition except the four from South Korea who remain barred from their national team.

In mixed doubles at the China Open, top seeds Xu Chen and Ma Jin of China knocked off No. 5 seeds Chan Peng Soon and Goh Liu Ying of Malaysia 21-15, 21-17.
