Rafa Nadal, gunning to become the first man to win seven French Open titles, will make sure he will celebrate his birthday in Paris if he beats Argentine Eduardo Schwank in a third-round tie at Roland Garros on Saturday. The second-seeded Spaniard, who will turn 26 on Sunday, is expected to roll over the world number 192 on Court Philippe Chatrier. Russian second-seed Maria Sharapova, chasing the only grand-slam title missing from her collection, will be back in action for the second day running when she faces Chinese 28th seed Peng Shuai.
