The sixth-seeded Indo-American pair had to sweat it out for little over two hours to get the better of their un-seeded opponents 7-6, 3-6, 6-2 on Saturday night. Even though Sania and Huber committed more unforced errors than their opponents, they enjoyed better share of break points conversion, utilising two out of the five opportunities that came their way.
The pair will face un-seeded pair of Shuko Aoyama of Japan and South African Chanelle Scheepers in their next round. Sania is also in the fray in the mixed doubles event where she is pairing up with Horia Tecau of Romania.
Sania and Tecau, who got a bye in the first round, are seeded second in the mixed doubles event and the duo will play all German combination of Martin Emmrich and Julia Goerges in the second round.
