Stosur withdraws from Indian Wells with leg injury

Sam Stosur has withdrawn from her quarterfinal against Angelique

Kerber at the BNP Paribas Open because of a right calf injury.

Kerber will move into the semifinals against either top-seeded

Victoria Azarenka or No. 8 Caroline Wozniacki, who play later on

Thursday.

Stosur says she hurt her calf muscle in the last game of a

three-set win against Mona Barthel on Tuesday. The Australian

didn’t practice on Wednesday and iced her leg. Stosur was five

minutes into her warm-up on Thursday when she realized she couldn’t

play.

She says this is only the second time she’s pulled out of a

match in her career and isn’t sure how long she’ll be

sidelined.
