Top seed Serena Williams lost just three games to advance to the second round of the Australian Open, the tournament she won last year in both singles and doubles. The four-time Australian Open champion defeated Poland's world No.72 Urszula Radwanska 6-2 6-1 and will next play Petra Kvitova of the Czech Republic.
Serena’s sister Venus beat Czech Lucie Safarova 6-2 6-2 to advance to the second round. The sixth-seeded Williams will try to improve on her last year’s result, when she was upset in the second round by Carla Suarez Navarro. Venus' opponent in the next round will be Austrian Sybille Bammer.
