S.Kisona conjured up arguably one of her biggest career wins after pulling off a huge 17-21, 21-13, 21-13 victory over India's Saina Nehwal to book a quarter-finals berth at the Swiss Open.
The former world number one may not be quite the force she used to be, but the victory was still nonetheless a massive major booster for Kisona, who endured a tough few months to find her best form.

It was a good day for the Malaysians as two mixed doubles pairs also sailed into the last eight.
Tan Kian Meng-Lai Pei Jing face fourth seeds Mathias Christiansen-Alexandra Boje, while Goh Soon Huat-Shevon Lai are up against William Villegar-Anne Tran.
It was, however, the end of the road for Ng Tze Yong, who crashed out of the men's singles after a 21-18, 13-21, 12-21 defeat to Indonesia' Jonatan Christie.
Ng took the first game after initiating a battling comeback from 7-1 down to win 21-18, but Christie was much more clinical in the second game, and kept a healthy lead throughout the game which he won 21-13.
The defeat took the wind out of Ng, who caved 12-21 in the decider.
Chen Tang Jie-Peck Yen Wei also lost to fifth seeds Thom Gicquel-Delphine Delrue in the mixed doubles.
