Already Assured of a semi-final berth at the BWF World Tour Finals, India’s PV Sindhu on Friday suffered a three-game defeat to top seed Pornpawee Chochuwong of Thailand in her third and final group A women’s singles match here on Friday.

Sindhu, a two-time Olympic medallist, couldn’t apply enough pressure on the World No. 10 Chochuwong to go down fighting 12-21, 21-19, 14-21 in a match that lasted an hour and 11 minutes. This was Sindhu’s third loss to the 2016 world junior champion Chochuwong in seven meetings.
