EASTBOURNE, England (AP) Petra Kvitova insists her confidence is ''pretty good'' despite recent poor results as she advanced to the third round of the Eastbourne International on Tuesday.
Fifth-seeded Kvitova, who has reached just one semifinal this year, beat Timea Babos of Hungary 6-4, 7-6 (5).
''I'm kind of feeling that I am playing well, even though I lost some of the matches in a couple of months,'' she said, including a second-round defeat in England at Birmingham last week.
The two-time Wimbledon champion broke in the first set to lead 5-4 against Babos but then had to fight off two break points as she closed out the set. In a tense second set, the Czech held four break points to lead 5-4 before Babos took her to a tiebreaker.
''It wasn't easy today,'' said Kvitova. ''She was serving really well.''
Caroline Wozniacki of Denmark also reached the third round by crushing seventh-seeded Samantha Stosur of Australia 6-2, 6-1, while former top-ranked junior Kristina Mladenovic of France upset fourth-seeded Swiss Timea Bacsinszky 6-1, 7-5.
I love grass,'' said Mladenovic. ''I don't have any surface that I don't like.''
