The top-seeded Indo-Brazilian duo served past Abigail Spears and Santiago Gonzalez 7-5, 6-7 (3) [10-8] in the second round encounter to keep their good work going.
The US-Mexican pair gave a bit of a hard time to the Sania-Soares combine but the experienced pair handled the pressure with ease.
Sania though had bowed out of the women's doubles event after losing the first round match to Su-Wei Hsieh of Chinese Taipei.
Indian veteran Leander Paes will also be seen in action along with his mixed doubles partner Martina Hingis later in the day.
