Top-seeds Sania Mirza and Martina Hingis routed the pair of Karolina Pliskova and Michella Krajicek to sail into the quarterfinals of the WTA Aegon International, in Eastbourne.

Sania and Hingis thrashed the unseeded Czech-Dutch pair 6-0, 6-2 in the opening round of $731000 grass court tournament.

The top seeds saved both the break chances in the opening set and broke their rivals three times to bagel them.

In the second they dropped serve once but capitalised on three breaks to close the contest in just 45 minutes.

The Indo-Swiss pair next face Hao-Ching Chan of Taipei and Flavia Pennetta from Italy in the quarter-finals.
