India's tennis sensation Sania Mirza has lost out on her French Open campaign, falling to Argentina's Gisela Dulko in straight sets in the first round.

Sania who is the first Indian woman to get a direct entry into a Grand Slam faced a tough task as the 30th seeded Dulko is considered to be a clay court specialist.

The 18-year-old who made a comeback last week after over a month off due to injury could not put up a fight against her Argentine opponent, conceding the match 3-6,3-6.
