Shoulder injury forces Sharapova to pull out of Key Biscayne tourney

KEY BISCAYNE, Fla. -- Maria Sharapova pulled out of the Sony Ericsson Open on Saturday, citing a shoulder injury.

The No. 5-ranked Sharapova is a two-time finalist at the hard-court tournament.

Her withdrawal came a day after her 18-match winning streak ended with a 6-3, 5-7, 6-2 loss to Svetlana Kuznetsova at Indian Wells, Calif.

"We certainly wish Maria a speedy recovery and hope she is able to return to the court quickly," Sony Ericsson Open tournament director Adam Barrett said.
