Top-seeded Caroline Wozniacki, No. 11 Kim Clijsters and others took care of business on Day 7 of the 2012 Australian Open, advancing to the quarterfinals.
But there are still four spots remaining in the quarterfinal bracket, which will be filled on Day 8.
There will be plenty of star power on display with Petra Kvitova and Maria Sharapova set to take the court in their respective matches.
So, with that being said, let's take a look at three women's matches that should provide plenty of excitement for spectators.
Ana Ivanovic (No. 21) vs. Petra Kvitova (No. 2)
Kvitova has burst onto the scene in women's tennis since winning Wimbledon in 2011.
She also made it to the quarterfinals at last year's Australian Open, something she'd like to improve upon this year.
Standing in her way is Ana Ivanovic, a veteran who made it to the Australian Open finals in 2008.
Neither of these players are at their best on hard courts, but they should still provide a great match.
Ekaterina Makarova vs. Serena Williams (No. 12)
Coming off a big victory against No. 7 Vera Svonareva, Makarova presents a huge challenge for Serena Williams.
Williams hasn't been herself lately but she's been playing pretty well too in this year's Aussie Open.
In her last match, Williams dominated Greta Arn 6-1, 6-1. If she can continue playing that well she can advance to the quarterfinals.
But, if she can't stay composed, Makarova can pull off another upset.
This match should provide some of the most exciting tennis of Day 8.
Sabine Lisicki (No. 14) vs. Maria Sharapova (No. 4)
Sharapova is looking to get back to her dominant ways.
After winning the Australian Open back in 2008, Sharapova hasn't been able to get back to the player she was back then.
She lost in the fourth round last year, something she doesn't want to repeat this year.
Look for her to come out strong against the very talented Lisicki.
This match should be hard-fought and exciting, but Sharapova should advance in the end.
