No. 2 Victoria Azarenka had to rally to reach the quarterfinals, but defeated No. 13 Ana Ivanovic on Tuesday 4-6, 6-3, 6-4. Azarenka overcame 30 unforced errors and 41 winners from Ivanovic to advance.
This is a match Ivanovic will be kicking herself over for a while. She shot herself in the foot with five double faults in the second set. In the third set when Azarenka double-faulted four times, Ivanovic couldn't take advantage.
Azarenka will now face Daniela Hantuchova in the quarterfinals.
No. 5 Li Na continued her winning ways, but she too had a less-than-easy path to victory. No. 24 Ekaterina Makarova pushed Li to three sets before the 31-year-old pulled out the 6-4, 6-7 (5-7), 6-2 win.
On the men's side, Lleyton Hewitt had his dream of capturing another Grand Slam thwarted in a five-set marathon with No. 21 Russian Mikhail Youzhny. After trailing 4-2 in the final set, Youzhny rallied to prevail 6-3, 3-6, 6-7 (3-7), 6-4, 7-5.
Here's a look at the matches scheduled for Tuesday evening and a look at the top seeds' matchups.
No. 1 Serena Williams vs. No. 18 Carla Suarez Navarro
In two previous meetings, Navarro has won a total of five games against Williams. Needless to say, the top seed is heavily favored in this match.
Suarez Navarro has been playing well during the tournament, but she'll have to be at her all-time best to seriously challenge Williams.
The latter hasn't dropped a set yet. To further contribute to Williams' superiority, she and sister Venus Williams have already bested Suarez Navarro and her partner Silvia Soler-Espinosa in doubles competition at the 2013 U.S. Open.
Chances are she makes it a double elimination over the 25-year-old Spaniard.
No. 1 Novak Djokovic vs. Marcel Granollers
Djokovic has only faced Granollers once, but he handled him easily. It was a straight-sets victory at the 2011 Australian Open.
Quietly, Djokovic has been dominant. He's only dropped more than two games in a set once this tournament.
Granollers has won three straight five-set battles to get to the fourth round. His chances of winning would have been slim had he played in three quick matches prior to meeting Djokovic.
After three grueling sessions, it seems he's at an even bigger disadvantage.
