Wimbledon 2012: Serena Williams & Petra Kvitova reach round four

Serena Williams fought back from a set down and set a new Wimbledon women's record of 23 aces to keep alive her bid for a fifth singles title. Williams, 30, had to dig deep to edge past China's Zheng Jie 6-7 (5-7) 6-2 9-7, while defending champion Petra Kvitova breezed into round four. "I definitely felt like it was a gut check for me," said Williams. "I never felt I would lose. I told myself to stay calm. I'm always strong mentally. That's not going anywhere." The American, who set the previous aces record of 20 in the 2009 semi-final against Elena Dementieva, stumbled in the first-set tie-break. But she romped through the second set before coming out on top in a nail-biting decider after two hours and 28 minutes on Centre Court. "I thought in the third set, if I'm going to go out I want to go out with a bang," said Williams, who served three times to stay in the match, winning each game to love. Williams, the sixth seed, will next play Kazakh wildcard Yaroslava Shvedova, who made history by achieving the first 'golden set' in Grand Slams against Sara Errani . French Open finalist Errani failed to win a single point during a 15-minute first set, in which Shvedova won 24 consecutive points, and eventually fell 6-0 6-4 to the world number 65.
