Saina Nehwal breezed past Chinese Taipei's Hsu Ya Ching while Parupalli Kashyap stunned World No. 5 Son Wan Ho in straight games to make it to the quarterfinals of the Indonesian Open Super Series badminton tournament in Jakarta on Thursday.
Saina, who slipped to World No. 3 on Thursday, thrashed Ching 21-13, 21-15 in a 36-minute contest to set up a clash with old foe Shixian Wang in the women's singles quarters.
Kashyap, meanwhile, upstaged Ho 21-11, 21-14 in just 36 minutes and will face top seed Chen Long in the men's singles quarterfinal.
However, Kidambi Srikanth bowed out after going down 21-14, 20-22, 13-21 to Ginting Anthony of Indonesia in a battle that lasted 54 minutes.
Saina, seeded second, put up a thoroughly clinical performance against her unseeded rival, clinching the first game in just 14 minutes.
Ching fought a tad harder in the second game but Saina dominated the proceedings just enough to pocket the match in just over half an hour.
World No. 12, Kashyap came up with a clinical display against Wan Ho, winning a total of 42 points as compared to just 25 won by the Korean.
The opening game turned out to be a cake walk for Kashyap. Having opened up a 4-0 lead, the shuttler from Hyderabad simply dominated the proceedings.
Kashyap continued to surge ahead and the closest the Korean could reach was 4-7 at one stage in the first game.
In the second game, Wan Ho bounced back with a 2-0 lead to begin with but Kashyap soon caught up with him at 3-3 and the battle continued till 6-6 before the Indian reeled off six points on the trot to make it 12-6.
There was no looking back for Kashyap thereafter and he eventually sealed the game and the match pretty comfortably.
