P.V. Sindhu, the other Indian in the fray, put up a strong fight against Tai Tzu Ying of Taiwan before suffering a narrow 21-13, 20-22, 8-21 defeat in a match that lasted for an hour.
Sindhu started well by winning the opening game. She had a comfortable 12-6 lead in the second game as well before Tai made a remarkable comeback. Tai equalised at 15-15 before Sindhu regained the lead at 20-19. But the Taiwanese shuttler held her nerves in the closing stages to clinch the second game and level the issue.
