French Open: Sania-Hingis battle into second round

Top seeds Sania Mirza and Martina Hingis were tested by Russian girls Daria Kasatkina and Alexandra Panova before getting through to second round of the women doubles event in French Open on Wednesday.

Sania and Martina -- the reigning Wimbledon, US Open and Australian Open champions -- prevailed 7-6(4) 6-2 in the opening round of the clay court Major, which they need to win to complete their non-calendar Slam.

Sania and Martina lost their serve thrice in the match as they battled 12 breakpoints in the contest. They next face the winners of the match between the pairs of Karin Knapp/Mandy Minella and Nao Hibino/Eri Hozumi.

After trading a few breaks, the two pairs were level 5-5 in the opening set. The top seeds had a set point in the 12th game but their fighting rivals stretched it to the tie breaker, which was again a tight affair but Sania and Martina prevailed.

The world number one team broke Kasatkina and Panova in the very first game of the second set but only to be broken back in the next. However, they broke them one more time and held their own for a 4-2 lead. Another break set them up for serving out the match which they did with ease, at love.
