Sharapova pulls out of Rogers Cup; blames stomach bug picked up at Olympics

MONTREAL - Former world No. 1 Maria Sharapova has withdrawn from the US$2.168 million women's Rogers Cup with a stomach ailment.

The 25-year-old told organizers she picked up the bug at the London Olympics.

Sharapova won silver at the Games when she lost in the final to Serena Williams.

She was replaced in the draw by Galina Voskoboeva of Kazakhstan.

"It's disappointing for our fans and for all of us, but it's part of the game," tournament director Eugene Lapierre said in a statement.
