Wimbledon 2013: Petra Kvitova battles her way to quarter-finals with victory over Carla Suarez Navarro Both were exposed as early as her first two service games, where a string of unforced errors saw her twice have to save break points. Kvitova refused to curtail her high-risk approach to winning points, with decidedly mixed results as the first set moved to 5-5. The 23-year-old finally came to life in game 11, needing just one break point to leave herself serving for the set. But if she thought Suarez Navarro would fold, she was in for a huge shock as the Spaniard broke her to love thanks to some inspired one-handed backhand play. Kvitova also blew a 3-0 lead in the tiebreak, which she took 7-5, and continued to struggle on serve early in the second set, saving another break point. But, suddenly, it all clicked into gear, as unforced errors became winners and tame serves aces. Kvitova needed just one break point to claim the serve of Suarez Navarro at 3-2 before going on to seal a third successive quarter-final appearance. Maybe she could trouble Williams after all.
