Sharapova out of 50

Maria Sharapova slid out of the top 50 in the new WTA rankings published Monday which saw Serena Williams still top of the heap though she is set to surrender her status to Dinara Safina next week.
Sharapova, who is currently injured, dropped 23 places and now stands 53rd on the computer.
The 21-year-old underwent shoulder surgery in October and only recently returned to training, missing a swathe of major tournaments, including the Olympics, and the US and Australian Opens.
Serena, a first-round loser last week at Marbella, is now skipping Charleston after the reigning US and Australian Open champion hurt her leg during the prestigious hardcourt tournament in Miami, an injury which dogged her in the claycourt tournament in Spain.
