The top seeds took an hour and 17 minutes to edge past experienced Italian pair of Sara Errani and Flavia Pennetta 1-6, 6-4, 10-6. This is the second victory in as many meetings for the Indo-Swiss pair over their opponents, having beaten the Italians in New York earlier this year.

Sania and Martina were shocked in the first set as their service games were broken thrice. To add to that, they double faulted twice, giving easy points to the Italian pair and losing the set in a jiffy. They looked totally out of rhythm and could not even earn a single breakpoint chance.

However, they fought back in the second set when they broke Sara and Flavia twice, once more than the Italians did, which was enough to win the set and push the match into the decider.

The reigning Wimbledon and US Open champions proved just a tad bit better in the super tie-break to clinch the match and enter the last eight.

They will next take on German-Czech pairing of Julia Goerges and Karolina Pliskova for a place in the semis.
