RAJGIR, Aug. 29 -- "This one's going to be tough. It is going to take something very special from (PV) Sindhu to prevent what many will be looking at as a fairly comfortable win for Wang Zhi Yi," commentator Bobby Griffin commented as the two shuttlers warmed up ahead of their women's singles third round clash. Most regular followers of the game wouldn't have questioned Griffin. After all, world No.2 Wang has been in top form this year with as many as seven finals.Many would've bet on her reaching the BWF World Championships podium this weekend in Paris. But few would have shown any confidence in Sindhu. Poor form, injuries, criticism about her game, questions about her motivation and future - the former world champion has had to endure quite a bit of late. But on Thursday, the 30-year-old Sindhu showed that the fire in her belly is well and truly burning as she brought out her vintage best to cause the upset of the tournament by ousting the Chinese world No.2 21-19, 21-15 in 48 minutes. The two-time Olympic medallist unshackled herself for the first time in months and was in absolutely smashing form. She raised her level, unleashing her power game to outplay one of the most dominant players this season. Unlike the first two rounds, world No.15 Sindhu didn't start slowly. On the contrary she was the aggressor and that took second seed Wang by surprise at the Adidas Arena. Just as she did during her prime, an extremely confident Sindhu anticipated Wang's shots and attacked at the net with her rocket smashes hitting the floor even before the Chinese could react. After the confidence boosting win, Sindhu will take on Indonesian ninth seed Putri Kusuma Wardani in the quarter-final against whom the Indian has a 2-2 record....
