Sania Mirza and her Swiss partner Martina Hingis have entered the women's doubles semi-finals of the Miami Open Tennis. The top seeded Indo-Swiss duo served past the Rodionova sisters, Anastasia and Arina, 6-3 6-4 in the quarter final 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 in mixed. The duo, which decided to unite in February, will now meet the seventh-seeded Hungary-French combine of Timea Babosand Kristina Mladenovic in the last-four clash.
