Agnieszka Radwanska defeated defending Istanbul champion Petra Kvitova on Tuesday, 6-3, 6-2 to kick off action at the 2012 TEB BNP Paribas WTA Championships. The previous three meetings between the two had all gone Kvitova's way.
"I'm just very happy about my performance," Radwanska said. "The first match is always tough and adjusting to a new surface is never easy, but I was playing really well from the beginning to the end of the match."
The loss by Kvitova ended a 25-match indoor win streak and leaves her with an uphill battle if she wants to make it out of the White Group and into the semifinals of the TEB BNP Paribas WTA Championships.
"The nerves were there, for sure—I was nervous the whole match," said Kvitova. "I'm disappointed in myself. I made a lot of errors in the match today; it wasn't good tennis from my side. But it's the WTA Championships, and I have another chance."
