Sania Mirza and Chia-Jung Chuang reached the doubles quarter-finals of the USD 220,000 MPS Group Championships.

Sania and her Chinese Taipei partner did win but not before some late scares.

The Indo-Taipei pair had to fight it out in a marathon three-setter to down Melinda Czink of Hungary and Lilia Osterloh of America 6-0 3-6 10-5 in the first round.

However, Sania-Chuang duo's route to the last four won't be a cakewalk as fourth seeded pair of Bethanie Mattek-Sands of America and Nadia Petrova of Russia awaits them in the next round.

Sania's campaign in the singles already came to a premature end with a straight sets defeat at the hands of seventh seed Alona Bondarenko in he opening round.
