India’s HS Prannoy progressed to the men’s singles semi-finals with a thrilling win over Taiwan’s Wang Tzu Wei at the India Open Super 750 badminton tournament here on Friday.

The 31-year-old, who had won the bronze medal at the Asian Games and World Championships last year, recovered from a slump in the second game and showed nerves of steel in the decider to eke out a 21-11, 17-21, 21-18 win over world No. 28 Wang in a 77-minute match.

Coming into the match with a 5-3 head-to-head count, Prannoy dished out an attacking game and constructed his rallies well, keeping his opponent to the back and often finishing points with steep smashes.

World No. 1 and defending champion An Se Young of Korea retired hurt against Singapore’s Jia Min Yeo after aggravating her knee injury in a women’s singles quarter-final match.

Jia Min will next face former world No. 1 Tai Tzu Ying, who beat China’s sixth seed He Bing Jiao 21-12, 21-12.
