No.2 seed Maria Sharapova was forced to retire in her quarterfinal match against Czech Petra Kvitova at the Pan Pacific Open in Tokyo. The Russian twisted her ankle with Kvitova leading 4-3 in the first set and it didn’t look promising for her as she immediately called for a trainer. This was a rematch of this year’s Wimbledon final, where the Czech beat her in straight sets 6-3, 6-4.
Kvitova will now play against Vera Zvonareva, who beat her Russian compatriot Maria Kirilenko comfortably 6-3, 6-3. The semifinals match is scheduled for Friday.
