Now that she's won all four, which is Sharapova's favorite?

Maria Sharapova said her French Open triumph was a greater achievement than her teenage 2004 Wimbledon breakthrough, which launched her on the road to international fame and fortune.

The Russian, one of the few genuine stars in the women's game, completed a career Grand Slam by beating Italy's Sara Errani 6-3, 6-2 on Saturday.

It was the 25-year-old's first Roland Garros title and fourth major of her career, but first since she recovered from a potentially career-ending shoulder injury.
