The top-seeded Indo-Swiss duo served past the Rodionova sisters, Anastasia and Arina, 6-3 6-4 in the quarterfinal encounter.

The Sania-Hingis pairing has been much-talked about in the tennis circuit and the top seeds lived up to the hype by claiming their first title win in their maiden appearance together in Indian Wells in March.

Hingis has won 11 Grand Slams in the team discipline (nine in women's and two in mixed) while Sania has claimed three Grand Slams (all in mixed).

The duo, which decided to unite in February, will now meet the seventh-seeded Hungary-French combine of Timea Babos and Kristina Mladenovic in the last-four clash.
