The world no.1 pairing of Sania Mirza and Martina Hingis continued their march towards the Women's Doubles title at the US Open, recording a convincing straight sets win against the Italian duo of Sara Errani and Flavia Pennetta.
Pennetta, who had already competed in a grueling women's quarter-final encounter against Petra Kvitova earlier in the day, looked visibly exhausted taking the court for a second time, and that made the Italians easy meat for the top seeds.
