Injured Sharapova pulls out of Toronto

Five-time Grand Slam champion Maria Sharapova on Thursday withdrew from next week’s WTA Rogers Cup tournament in Toronto with a sore left forearm, Tennis Canada announced.

The move came a day after the former world No 1 from Russia withdrew from the WTA event in Stanford, California, before a second-round match.

The injury casts further doubt over Sharapova’s participation at the US Open, which starts in New York on Aug 28.

Due to her low ranking, Sharapova, who returned to the circuit earlier this year after serving a 15-month doping suspension, will need a wild card to play in the main draw of the tournament.
