Beijing Olympics winners Du Jing and Yu Yang overcame teammates Cheng Shu and Zhao Yunlei 21-15, 21-15 to capture the women's doubles title at the China Masters badminton super series in Changzhou on Sunday.

Du and Yu led 11-8 to enter the technical timeout and never looked back in the opening set.

The two pairs changed leads in the second but Du/Yu again led 11-8 and quickly to extend their edge to 15-8.

"This victory is such an encouragement for us because my injury stopped us from producing good performance after the Olympics," said Du, 25, who has been bothered by knee injury since their triumph in Beijing.

"I still have a long way to reach as good a form as in the Beijing Olympics last year," she added.

Du and Yu will compete in the Japan Open kicking off two days later.

"Hopefully we can win again in Japan," said Yu.

World champions Cai Yun and Fu Haifeng withdrew from the men's doubles final due to Cai's injury, surrendering the title to teammates Guo Zhendong and Xu Chen.
