New York, Sep 5 (IANS) The India-Pakistan pair of Rohan Bopanna and Aisam-Ul-Haq-Qureshi marched into the quarterfinals of the US Open with a 6-2, 6-3 victory over Paul Hanley and Dick Norman in a third round men's doubles match here Sunday.

Sania Mirza, however, had to taste defeat with her Russian partner Elena Vesnina. The sixth seed pair bowed out of the competition after losing to the Czech duo of Iveta Benesova and Barbora Zahlavova Strycova 6-7, 6-7 in the third of the women's doubles.

Bopanna-Qureshi, last year's finalists and seeded fifth in the current edition, got the better of the Australian-Belgian combine of Hanley and Norman in 60 minutes.

They next meet Britan's Colin Fleming and Ross Hutchins, who got a walkover from 13th seed pair of Marcel Granollers and Marc Lopez.

India's best bet at the Open, Leander Paes and Mahesh Bhupathi, play their third round match against Somdev Devvarman and Treat Conrad Huey later in the day.
