World No. 1 Caroline Wozniacki has a tough road ahead of her as she pursues her first ever Grand Slam title, starting with last year's Australian Open winner Kim Clijsters.
The Top 4 seeds from the women's bracket are in still in play as the 2012 Australian Open moves forward with the quarterfinals on Tuesday. The day 9 matchups are guaranteed to produce a semifinal of highly-seeded players. No. 3 Victoria Azarenka is set to take on No. 8 Agnieszka Radwanska, and No. 1 Caroline Wozniacki's matchup against last year's champion, No. 11 Kim Clijsters, is perhaps the most highly anticipated so far of the tournament.
Despite her spot atop the world rankings, Wozniacki is still looking for her first Grand Slam title. The 21-year-old is putting in a strong bid so far, having yet to drop a set in this year's tournament. She was forced into a tiebreak in her second round matchup against Anna Tatishvili and was pushed to 5-5 in the second set of her match against No. 13 Jelena Jankovic. Otherwise, the extremely consistent Wozniacki hasn't faced much adversity. Clijsters was able to wear out No. 5 Na Li by the end of their three-set dog fight on Sunday, and will attempt break Wozniacki when the two face off in Rod Laver Arena.
The winner of Clijsters-Wozniacki will have to face either Azarenka or Radwanska in the semifinals. Azarenka heads into the quarterfinals match having lost just 12 games in eight sets played. Granted she has yet to face a ranked opponent, but her dominance has been notable. Radwanska took out No. 22 Julia Georges in dominant fashion in Round 4, winning 6-, 6-1. Like Azarenka, she has dominated throughout the Australian Open, dropping just 16 games in her eight sets.
No. 4 Maria Sharapova and No. 2 Petra Kvitova both earned somewhat favorable draws, getting pitted against unranked Ekaterina Makarova and Sara Errani, respectively, for their Wednesday matches. Sharapova struggled against Sabine Lisicki on Monday, however, dropping the first set before winning the final two to advance, and could have a tough time against Makarova. The 23-year-old Marakova has beaten three ranked opponents to make the quarterfinals, including a 6-2, 6-3 win over Serena Williams on Monday.
Kvitova survived a tiebreak in the second set in her win over Ana Ivanovic to advance. She has gone to three sets just once so far in the tournament, beating Carla Suarez Navarro in Round 2, 6-2, 2-6, 6-4. Errani has been playing excellent tennis as well. The Italian has dropped just one set so far in the tournament, and has not given up more than two games in any of the eight sets she has won.
