Australian Open 2012 Schedule: Jan. 20 TV Schedule, Matches and Bracket Guide

Welcome to the third round of the Australian Open. Day 5 will prove to be a memorable one down under as the heavy hitters continue to make their way to the final rounds. 

Caroline Wozniacki and Kim Clijsters are on a collision course but have to get past a couple of underrated opponents to move on in the greatest tournament Down Under. 

Americans will have plenty of reason to keep an eye on the Aussie. John Isner takes on Feliciano Lopez in third-round play. With Mardy Fish flying home, Isner remains one of the last hopes for American glory.

Men's Storylines

Rafael Nadal has been on cruise control so far and should dispatch with 119th ranked Luckas Lacko rather quickly. 

Roger Federer has a harder draw against a big-serving Ivo Karlovic. There will be plenty of aces in this match, but the Swiss maestro should still dominate the match. 

With Andy Roddick bowing out from injury and Mardy Fish losing, John Isner will have to do for Americans hoping to get some semblance of glory from the Aussie. He will have to be on his game to get past a tough Spaniard in Feliciano Lopez. 

Women's Storylines

We will see how Caroline Wozniacki's wrist is feeling in her first real test in Monica Niculescu. This will be no cakewalk and could serve to exacerbate the lingering injury. 

Then we come down to what could be the match of the day. Daniela Hantuchova has what it takes to down Kim Clijsters with some of the better form we have seen from her. 

Clijsters is rolling right now meaning we will get two top-notch stars meeting just as they begin to heat up. Clijsers is feeling good at Melbourne as she needed just 47 minutes to beat Stephanie Foretz Gacon of France 6-0, 6-1 in the second round.
