"It was nervous," Petra Kvitova said after defeating Vera Zvonareva in straight sets in the first round-robin match of the WTA Championships in Istanbul today. It wasn't a trouble-free match for Kvitova; she went "in" and "out," as she is known to do. This was not only the first match of the Championships, but Kvitova's first WTA Championships match ever. The good news for her is that the matches are played on an indoor court, and she is now 15-0 on indoor courts for the 2011 season.
Caroline Wozniacki hadn't lost to Agnieszka Radwanska for four years, but today, it looked as though she might. However, in what turned out to be a really good and sometimes exciting match, the world number 1 pulled off the win after two hours and 39 minutes of play. Wozniacki prevailed 5-7. 6-2, 6-4, after Radwanska fought back for a few sets and saved a match point on her own serve.
Sam Stosur hadn't beaten Maria Sharapova in nine tries, but today, in their tenth career match, she defeated Sharapova 6-1, 7-5.
Kvitova and Wozniacki are in the Red Group, and Stosur is in the White Group.
On Wednesday, Stosur will play Victoria Azarenka and Sharapova will play Li Na as part of the White Group competition. In the Red Group, Wozniacki will play Zvonareva.
