Australian Samantha Stosur shocked top seed Serena Williams in the WTA Bank of the West Classic quarter-final Friday. Stosur snapped Serena's nine-match win streak with a 6-2, 3-6, 6-2 victory to book a Saturday semi-final berth against French eighth seed Marion Bartoli, who upset Serbian fourth seed Jelena Jankovic 3-6, 7-6 (7/3), 6-3. "It's one of the biggest, if not the biggest win of my career," Stosur said. "I would like to take it one more step. I would love to make it to another final."
Serena Williams, the 11-time Grand Slam champion who won Wimbledon and the Australian Open this year, took both prior meetings against Stosur but was forced to save four match points in a three-set win in January at Sydney. "She played well and didn't do anything bad," Williams said. "She went for broke and struck all her balls as hard as she could. She never lets you get into a rhythm. "She had a lot of lucky shots. She's a good framer. But it's obviously all talent. She has mastered that."
Stosur denied Williams on 9-of-10 break-point chances and denied the 34-time WTA champion's comeback bid at the 700,000-dollar hardcourt tournament. "We don't always play our best tennis every single day," Stosur said. "Maybe she didn't play her best and I played very well."
