The Olympic silver-medallist P V Sindhu crashed out of the Japan Open badminton tournament after a second successive defeat to local favourite Akane Yamaguchi.

Sindhu lost to Yamaguchi 18-21 15-21 in a 50-minute women's singles quarterfinal match. Yamaguchi had beaten Sindhu in the final of the Indonesian Open last week. 

Sindhu was leading 12-7 in the first game but she squandered the advantage as her reigning Asian champion opponent clawed her way back to level the scores at 14-14. From there on, Sindhu lost momentum allowing Yamaguchi to surge ahead to 18-15 and then to 20-16.
