Sania Mirza and her partner Chia-Jung Chuang advanced to the semi-finals of the Madrid Open after Russian-Belarussian duo of Victoria Azarenka and Elena Vesnina conceded their quarter-final match.
The unseeded Indo-Taipei duo were leading 2-0 in the first set when their opponents pulled out due to an injury in Azarenka's left knee.
Sania-Chuang will next face third seeds Lisa Raymond of the US and Kveta Peshke of Czech Republic in the last four stage.
The other semifinal will be played between top seeds Cara Black of Zimbabwe and American Liezel Huber and the fourth seeded Australian pair of Samantha Stosur and Rennae Stubbs.
Sania had earlier failed to make the cut into the main draw of the singles event after losing 3-6, 3-6 to Aravane Rezai of France in the first round qualifiers.
