Treesa Jolly-Gayatri Gopichand upset World No. 2 Baek-Lee; PV Sindhu goes down to Marin

This is Sindhu's sixth loss on the trot against her arch-rival, dating back to 2018.

PV Sindhu suffered yet another setback against Carolina Marin, but the rising Indian women's doubles pair of Treesa Jolly and Gayatri Gopichand stunned world number two Baek Ha Na and Lee So Hee of South Korea to enter the quarterfinals at Singapore Open here on Thursday. Double Olympic medallist Sindhu blew away an 18-15 lead in the decider to go down to familiar rival Marin in a thrilling 21-13 11-21 20-22 women's singles last-16 match. It was Sindhu's sixth loss on the trot against her arch-rival, dating back to 2018.

The Commonwealth Games bronze medallist duo of Treesa and Gayatri kept the Indian flag flying high by eliminating Baek and Lee 21-9 14-21 21-15 in close to one-hour battle.

This was the world number 30 Indian duo's maiden win from three meetings against the world number two Korean pair.

They will be up against another South Korean pair -- sixth seed Kim So Yeong and Kong Hee Yong -- in the quarterfinal of the BWF World Tour Super 750 event.

The Indian duo had lost to the Korean pair at the Hangzhou Asian Games pre-quarterfinals last year.
