The question "What's wrong with Petra Kvitova?" popped up again today as the Czech star went to pieces in the Tokyo semifinal after going up 4-0, then 5-1, in her first set against Vera Zvonareva. Zvonareva, reacting to the pressure put on her by Kvitova, couldn't do much of anything for most of that set. But then she broke Kvitova, and after that, the 5th seed's backhand, second serve and confidence began to decrease.
Slowly at first, Kvitova's game unraveled. Zvonareva, having come back from almost certain loss, practically cruised through the first set tiebreak. Then it was effectively over for Kvitova, whose game became a mass of unforced errors. She got a little of her hitting savvy back toward the end, but it was too late. Zvonareva's 7-6, 6-0 win puts her into the Tokyo final.
Her opponent will be Agnieszka Radwanska, who defeated Victoria Azarenka 6-3, 4-6, 6-2.
In doubles, top seeds Liezel Huber and Lisa Raymond defeated Azarenka and Maria Kirilenko when Azarenka and Kirilenko retired early in the first set. Gisela Dulko and Flavia Pennetta defeated Vania King and Yaroslava Shvedova 4-6, 6-3, 10-8.
