MONTREAL (AP) -- Maria Sharapova says she has pulled out of the Rogers Cup in Montreal because of a left foot injury.
The Russian star reached the final at the Cincinnati Masters on Sunday, but says she started to feel pain in her heel in the second set of the 2-6, 7-6 (4), 6-2 loss to Kim Clijsters.
Sharapova says on her website that the pain ``kind of scared me, so I have been forced to pull out of Montreal. I am hoping I just need a few days of rest.''
The three-time Grand Slam champion moved up three spots to No. 12 in the WTA rankings released Monday.
