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 on Tuesday.
Sania and Hingis thrashed the unseeded Czech-Dutch pair 6-0, 6-2 in the opening round of the US$ 731,000 grass-court tournament, the last warm-up event before Wimbledon.
The top seeds saved both break points in the opening set and broke their rivals thrice to hand them a bagel.
In the second set, they dropped serve once but capitalised on three break chances to close the contest in just 45 minutes.
In the quarterfinals, they will face Hao-Ching Chan of Taipei and Flavia Pennetta of Italy.
