Serena and Venus Williams both advanced in the Australian Open against their unseeded opponents on Thursday in Melbourne.

Serena, the defending Australian Open champion, is looking to add to her resume of 11  major singles titles. She defeated Petra Kvitova of the Czech Republic, 6-2, 6-1 at Hisense Arena.

Her sister, Venus, also advanced earlier in the day, defeating the Austrian Sybille Bammer, 6-2, 7-5.

Venus has won seven major titles in her career but hasn't advanced past the fourth round of the Austrailan Open since 2003. She is slated to play left-handed Aussie Casey Dellacqua in the third round.

There is no chance at a Williams final, as the sisters will meet in the semifinals if they advance that far.

Serena is one of the favorites to win the tournament and is looking stronger then her sister thus far. She has won the Australian Open four times and plans on winning it again.

"I feel like if I can play well, I can beat anybody," Serena told the media after her match.

She is set to take on 32nd-ranked Carla Suárez Navarro, a 21-year-old from Spain in the third round. Suárez Navarro beat Andrea Petkovic of Germany, 6-1, 6-4.
