Tennis – Williams beats Vaidišová at Australian Open

Defending champion Serena Williams revived memories of last year's stunning Australian Open win Sunday when she overpowered Czech 12th seed Nicole Vaidišová to reach the quarter-finals. Williams ended the 18-year-old's Open campaign with a 6-3, 6-4 win to set up a meeting with either third seed Jelena Jankovic of Serbia or Australian hope Casey Dellacqua. Vaidišová committed 25 unforced errors, more than doubling Williams' tally, admitting her opponent's on-court dominance unsettled her. "I had my chances, especially in the second set but didn't chose the right shot, maybe went for too much," the 18-year-old said.
