BWF World Tour Super: Host China secured four of the five titles at the badminton China Open here on Sunday after the men's doubles pair was outscored in the final following a waist injury to Ren Xiangyu during the first set.

In the men's doubles final, China's He Jiting/Ren started strong, winning the first set 21-13 with ease. However, Ren strained his waist while diving for a save, Xinhua reports.

"I felt it wasn't going to work," Ren recalled after the match. Although the coach suggested retiring after the first set, Ren decided to continue.
