Olympic silver-medallist P V Sindhu has entered the semifinals of the Hong Kong Super Series badminton tournament. In the quarter-final at the Hong Kong Coliseum today, Sindhu overcame Singapore's Xiaoyu Liang in three games 21-17,21-23, 21-18. The match lasted an hour and 19 minutes. However, fifth-seeded Saina Nehwal bowed out of the event, as she was stunned by unseeded local shuttler Cheung Ngan Yi 8-21 21-18 19-21. The quarter-final contest lasted an hour and 11 minutes. Had the former World No. 1 Saina won her match, she would have met Sindhu in an all Indian battle in the semifinals. The only time Saina and Sindhu clashed at the international circuit was at the 2014 India Grand Prix gold tournament. That time,Saina emerged as winner. In the Destinational Dubai ranking for the BWF Super Series Final, Sindhu is ahead of Saina by a few points. Hence, when the rankings come out next week, Sindhu is likely to qualify for the prestigious tournament to be held next month.
