NEW DELHI (PTI) - Sania Mirza feels that she has a '50-50 chance of winning the womens doubles final at the French Open along with partner Elena Vesnina. Sania and her Russian partner, seeded seventh, will take on unseeded Czech duo of Andrea Hlavackova and Lucie Hradecka in the final today (Friday).. Sania said since their rivals are also in good form, it would be a good battle on Friday and said the seedings at this stage lose meaning. Sania Mirza had become the first female tennis player to win a Grand Slam when she won Australian Open mixed doubles in 2009 with compatriot Mahesh Bhupathi. If she and Elena manage to win Fridays final, Sania will also become first woman tennis player to win a womens doubles Grand Slam title.
