$ 0 0 PetraKvitova booked a Wimbledon semifinal showdown against fellow Czech Lucie Safarova after ending the giant-killing run of Barbora Zahlavova Strycova with a 6-1, 7-5 victory.Kvitova, the sixth seed, won her only Grand Slam title at Wimbledon in 2011 and is now just two wins away from emulating that achievement thanks to her dominant quarterfinal display on Centre Court. PetraKvitova believes her experience of winning the Wimbledon title three years ago could be the decisive factor when she faces Lucie Safarova in an all-Czech semi-final at the All England Club. After a series of shock defeats for Serena Williams, Li Na and Maria Sharapova, sixth seed Kvitova is the only former Grand Slam winner left in the women's draw and that could a crucial advantage at the business end of the tournament. Away from Wimbledon, the 24-year-old has struggled to sustain the brilliant form she showed in winning the her maiden Grand Slam crown in 2011 with a shock final victory over Sharapova. Lucie Safarova of Czech Republic plays a return to Ekaterina Makarova of Russia during their women's singles match at the All England Lawn Tennis Championships, in Wimbledon, on July 1, 2014. The 24-year-old took 88 minutes to see off world number 43 Zahlavova Strycova, hitting 29 winners to just five from her Czech opponent, who came up short after defeating Chinese second seed Li Na and former world number one Caroline Wozniacki en route to the last eight. Kvitova's clash against 23rd seed Safarova will mark the first time two Czech women have made the last four at a Grand Slam since Hana Mandlikova and Helena Sukova at the 1986 French Open. Recent form suggests Kvitova will once again prove the scourge of her compatriots. Safarova has finally made it to the last four of a major at the 37th attempt. The pair, both left-handers, are good pals, but having to put aside friendships while on court has become a familiar feeling for Kvitova at this year's tournament. Kvitova and Safarova's advances to the semi-finals means there are two Czech women in the last four at a Grand Slam for the first time since Hana Mandlikova and Helena Sukova at the 1986 French Open. It is an advantage Kvitova hopes to exploit and she said: "Of course it can help me that I will know what I'm doing out there, how nervous I will be, these things. It's not a very typical experience (to be in a semi-final). Clash with Safarova will mark Kvitova's third appearance in the Wimbledon semi-finals and her fifth last-four match at the majors, while in contrast her opponent will be breaking new ground as she plays in her first Grand Slam last-four tie. But Kvitova comes alive on the grasscourts of south-west London, where her booming serve and powerful groundstrokes have made her a serious force.
