The 2012 Australian Open has been an exciting tournament so far.

On the men's side of the bracket, we are edging ever closer to a potential semifinal match between Rafael Nadal and Roger Federer.

But, standing in their way are two talented tennis players in Juan Martin Del Potro and Tomas Berdych.

How did these four players fare on Day 7 of the tournament?

Let's take a look at three lessons we learned about this portion of the bracket.


Rafael Nadal is Playing as Good as Ever

Nadal has been cruising through this year's Australian Open, winning every single one of his matches in straight sets.

His knee isn't bothering him as much anymore and he's moving around well.

He's also limited fatigue this week by not wasting any time eliminating his opponents. Berdych is going to have his hands full if he wants to pull off the upset against the Spaniard.

When Nadal is moving laterally as well as he is now, he's nearly unbeatable.


Juan Martin Del Potro is Going to Be a Tough Out

Del Potro earned a spot in the semifinal against Roger Federer by demolishing Philipp Kohlschreiber in Round 4.

He's one of the hottest players in the tournament and will be a huge challenge for Federer.

When Federer was on an outstanding run in the U.S. Open, winning the tournament in five straight years, it was Del Potro who finally ended the streak, beating him in the finals of the 2009 tournament.

If anyone can slow down Federer's momentum, it's Del Potro.


Tomas Berdych Doesn't Like Getting Hit By Tennis Balls

Berdych won a very hard-fought match against Nicolas Almagro, but didn't shake his hand afterwards.

Apparently, he was still upset about a point in which Almagro hit him in the right arm with a shot.

He's going to have to keep his composure better than he did against Almagro when he plays Rafael Nadal in the quarterfinals.

Nadal will force him into mistakes if he doesn't stay calm and collected.
