Australian Open 2012: Petra Kvitova shrugs off embarassing missed shot against Ana Ivanovic The tall left-hander broke Ivanovic twice in the first set and once in the second, and after forcing the tiebreak with some big serves she took control, quickly opening a 6-2 lead and sealing it on an Ivanovic error. "I'm lucky that I played at 11 o'clock," she said, referring to the hot conditions at Melbourne Park. I am happy that I won the second set because in the end it was very tough to come back. I am lucky that I'm not playing a third set. Kvitova used her power from both sides of the court to trouble Ivanovic, smashing 30 winners to her opponent's 14. "You really have to get that hit on the ball, otherwise she likes to dominate and step up and take her chances," Ivanovic said. She's playing well. Meanwhile Kvitova received glowing praise from Martina Navratilova, the first great Czech left-hander, who described her as the complete package. " (She has) power everywhere, she can change the direction of the ball really well on both sides," Navratilova said. Usually (with) players it's just maybe the backhand or the forehand, but she can do it on both sides. Great serving and she mixes it up well. And her attitude is fantastic. She's really fired up from the get-go. Today she hit a whiff on the overhead - embarrassed as heck. Shanked like six balls in a row, but got it together, held serve, 30-all comes up with a big serve. In years past and even last year she would lose those matches or lose her concentration. But now she gets it back together. She's tough.
