MELBOURNE (Reuters) - Venus Williams followed younger sister Serena into the second round of the Australian Open Tuesday with a 6-2 6-2 demolition of Lucie Safarova.

World number one and Australian Open champion Serena had earlier produced a similarly clinical performance against Poland's Urszula Radwanska on center court. The sixth-ranked Venus did not allow the 22-year-old Safarova to settle in the first set, racing out to a 4-1 lead before she broke for the second time to seal it.

Safarova broke the first game of the second set, but it was all the 29-year-old American would give her Czech opponent and she immediately broke back before romping to victory in just 71 minutes.
