Two-time Olympic medallist PV Sindhu progressed to the quarterfinals, while Kiran George delivered a gritty performance under pressure to keep the home flag flying in men's singles at the India Open badminton tournament in New Delhi on Thursday. Title contenders Satwiksairaj Rankireddy and Chirag Shetty, who had won the 2022 edition, recovered from an opening game reversal to beat Japan's Kenya Mitsuhashi and Hiroki Okamura 20-22 21-14 21-16 to inch closer to the crown. "I think they were quite good in their flat exchanges. As I said, we can speed up controlling easy errors which we shouldn't have. I think we were cruising quite comfortably in the first game, but happy that we could. However tired the game was, we still managed to beat," Chirag said.
