Indian shuttler P.V. Sindhu caused a huge upset, stunning World No.2 Wang Yihan of China in straight games to enter the semi-finals of the women's singles category at the ongoing Rio Olympics.
Faced with a much higher rated opponent, the 21-year-old from Hyderabad scripted a 22-20, 21-19 victory in 54 minutes over the former World No.1 at the Riocentro Pavilion 4 here on Tuesday.
Sindhu will face World no.6 Nozomi Okuhara of Japan in the last-four stage. Okuhara defeated compatriot Akane Yamaguchi 11-21, 21-17, 21-10 in a hard-fought all-Japan quarter-final clash which dragged on for one hour and eight minutes.
Wang, who had taken silver at the 2012 London Olympics, was expected to be the stronger of the two, but it was Sindhu who dominated most of the exchanges.
The World no.10 Indian won the majority of the long rallies and used her power-packed smashes and cross-court shots to good effect.
