Defending WTA Championships champion Petra Kvitova gets teary-eyed in her press conference after her 6-3, 6-2 loss to Agnieszka Radwanska in Istanbul. Kvitova committed 41 unforced errors in the match.

“It was a little bit different, but the nerves was there for sure,” Kvitova told reporters. “I was nervous all the match. I felt my fingers weren’t still moving and I didn’t move on my legs. I’m disappointing in myself. I had a lot of errors and it wasn’t good tennis from my side. … Here it’s top eight players in the world. I think that it’s not that big pressure because you don’t have someone who is around 100 in the first round for example. But, still, if you are not playing like some matches before and now you have player who’s No. 4 in the world, it’s not easy to be relaxed.”
