On a day that can only be described as scorching in Melbourne on Thursday, one match seemed to stand out ahead of the others. That was the No. 9 seeded Petra Kvitova taking on 18-year-old Laura Robson. The British rising star made it to the fourth round at the U.S. Open last year and has shown some signs that she's ready to take the next step, and her play in the second round at Rod Laver showed just that.

After dropping the first set 2-6, Robson bounced back with a solid 6-3 second set win to set up both players for a lengthy third set. The best part might have been how Robson scratched back in a third set that saw her go own 3-0 to start, and ended with her serving out the match to win the final set 11-9.

It definitely wasn't the prettiest of matches, especially with how poorly Kvitova was serving the entire time, but the English teenager is moving on in one of the biggest upsets yet of this 2013 Australian Open.

The top seeds move on easily -- It was exactly what you'd expect from the likes of Roger Federer, Andy Murray, Serena Williams and Victoria Azarenka in their second round matches.

Federer and Murray both dusted their opponents in straight sets while Williams and Azarenka combined to drop just three total games in their matches on Thursday.

Williams, who hobbled off the court in her opening match after rolling her ankle, seemed perfectly fine just two days later, hitting 10 aces and 28 winners in just under over a hour on court. Williams almost added another win when her and sister Venus took down their first round opponents 6-3, 6-1.
