Former champion Serena Williams shocked the French Open crowd, and herself, by losing to Virginie Razzano in the first round on Tuesday, her earliest exit from a grand slam in the 47 appearances she has made in an outstanding career.    

Italian Schiavone and Russian Maria Sharapova, who has won every grand-slam event except the French, both enjoyed a fine start to this year's tournament.

Nadal went into the second round with a 6-2 6-2 6-1 thrashing of Italian Simone Bolelli. Murray comfortably beat Roland Garros debutant Tatsuma Ito of Japan 6-1 7-5 6-0 on Suzanne Lenglen Court.
