It's still early at the ATP World Tour Finals in London, but Wednesday will prove crucial in deciding who advances out of Group A. 

That's because the leaders of the group, Rafael Nadal and Stanislas Wawrinka, will face each other. 

Nadal dominated compatriot David Ferrer, 6-3, 6-2, to jump into an early lead in the group, while Wawrinka outlasted Tomas Berdych, 6-3, 6-7, 6-3, to slot into second place. 

Not only will the winner of that one put himself in terrific position to advance to the semifinals, but the match between Ferrer and Berdych will essentially serve as a lose-or-go-home battle. 

Let's take a look at Wednesday's complete schedule, courtesy of BarclaysATPworldtourfinals.com.

Not only has Nadal never lost to Wawrinka in 11 career matches, but he has never dropped a set to the Swiss. 

That being said, Wawrinka, who has always had loads of potential, is enjoying a career-best season, and a couple of weeks ago, he was able to push Rafa in a tightly contested first set in Shanghai. 

Don't get me wrong, Nadal should win this one with relative ease. After losing to Ferrer in Paris, there were doubts about his indoor form, but he emphatically erased any of those concerns with a straight-sets win over the Spaniard on Tuesday. 

Wawrinka shouldn't be overlooked, however, as this could end up a lot closer than many are expecting. 

David Ferrer vs. Tomas Berdych

Ferrer has won eight of 11 career matches against Berdych, and if weren't for how inconsistent Ferrer looked against Nadal, I would feel comfortable in his chances of making it nine wins out of 12 meetings. 

The Spaniard advanced to the finals in impressive fashion in London before losing a hard-fought battle against Novak Djokovic, and it seemed as though he was primed to make a lot of noise in London. Now, it's tough to decipher the usually consistent Ferrer.

Of course, Berdych has struggled indoors this season. 

He lost to world No. 75 Ivo Karlovic in Basel, Switzerland, and followed that with defeats of Ferrer in Paris and now Wawrinka.

It's hard to imagine Ferrer losing this one.
