Saina Nehwal stormed into the quarterfinals of the All England championships with a 21-10, 21-17 win over France's Pi Hongyan in the second round here on Thursday.

The fourth-seeded Indian, who had lost to Pi in all five meetings, completely dominated the 34-minute contest. She called the shots right from the start, allowing the 23rd-ranked Frenchwoman to win just 10 points in the first game.

Though Pi put up a stiffer resistance in the second, Saina won the big points to seal the issue in her favour. That the Indian won 42 of the 69 points played clearly reflected her superiority.

Jwala-Ashwini out

It was, however, not a good day for Gutta Jwala and Ashwini Ponnappa as they lost to the second-seeded Chinese pair of Qing Tian and Yunlei Zhao in the second round.

The unseeded Indian combination went down 10-21, 15-21 in exactly half an hour.

On Thursday, former title winner Peter Gade of Denmark proved the highest profile loser on a marathon day's play.

Gade and Englishman Rajiv Ouseph started their match 70 minutes past midnight with Ouseph triumphing 17-21, 21-16, 21-14 to claim what was easily the biggest win of his career.

Four-time All England winner Lin Dan began his quest for another title with a 21-18, 21-15 victory over India's Ajay Jayaram while Germany's Marc Zwiebler overcame P. Kashyap's challenge 21-13, 15-21, 21-9 in another first round clash.
