Kvitova forced out of St. Petersburg Ladies Trophy with illness
Petra Kvitova, who was seeded as nr. 3 and is a previous champion, was forced to pull out of the St. Petersburg Ladies Trophy prior to her quarter final due to illness.
Kvitova was playing Ekaterina Alexandrova in the last quarterfinal on Friday's schedule.
"I'm really sorry to withdraw from the St. Petersburg Ladies' Trophy due to illness," Kvitova said in a statement.
"I wasn't feeling well during my match yesterday and hoped I would feel better today, but unfortunately, that's not the case. I'm sorry not to play in front of the fans here in this beautiful city. I wish the tournament a great finish and hope to be back again next year."
Alexandrova will play now in her second semi final of the season against the winner of the match between Kiki Bertens and Anastasia Potapova.
