The top-seeded Indo-Swiss pair took just 90 minutes to get past the challenge of fourth-seeded Timea Babos of Hungary and Kristina Mladenovic of France 6-4, 7-5 in their final round-robin match and finish on top of their group with a 3-0 record.
By virtue of this win, Sania and Martina had avenged their loss to the same pair the last time they played in Rome this year.
Saina and Martina lifted their game just at the right time and made full use of the only two breaks of the match they got. They got break point opportunities at 4-all in the first set and 5-all in the second, and grabbed the chances.
Muguruza, Kvitova make it
Meanwhile in singles, Garbine Muguruza continued her dream debut by completing round robin playwith a perfect 3-0 record to advance to the semifinals after a hard fought 6-4, 4-6, 7-5 victory over Petra Kvitova.
By topping the White Group, the Spaniard set up a showdown against Poland’s Agnieszka Radwanska while Kvitova (1-2) received a huge boost from her Czech Fed Cup teammate Lucie Safarova (1-2), who beat Angelique Kerber to help her advance. Germany's Kerber (1-2) only needed to win a set in Friday’s second match to move on but the already-eliminated Safarova (1-2) found her best form of the week to blast the German off the court.
THE RESULTS: White Group: 2-Garbine Muguruza bt 4-Petra Kvitova 6-4, 4-6, 7-5; 8-Lucie Safarova bt 6-Angelique Kerber 6-4, 6-3.
Doubles: 1-Martina Hingis & Sania Mirza bt 4-Timea Babos & Kristina Mladenovic 6-4, 7-5. — Agencies
