The season-ending championships for the ATP are a round robin tournament. The eight players are placed into two groups of four. They play three matches in the round robin format against each player in their respective group.

From there, the two players with the best records in each group progress to the semifinals. The players who survive that bracket will meet in the final to determine the champion.

The winner of the tournament will receive 1,500 rankings points. The players lose 200 points for each loss during the round robin stage.

Needless to say, the stakes are high. Here's a look at the rankings, per the ATP as of Oct. 28. Below the list is a look at the two favorites and a sleeper for the event.

1. Rafael Nadal
2. Novak Djokovic
3. David Ferrer
4. Andy Murray — out with injury
5. Juan Martin del Potro
6. Roger Federer
7. Tomas Berdych
8. Stanislas Wawrinka
9. Jo-Wilfried Tsonga — Loss to Kei Nishikora on Oct. 29 cost him a spot in his bracket, per CNN.
10. Richard Gasquet

Favorites

Rafael Nadal

Though he has slipped up a bit recently, Rafa's performances in Grand Slam tournaments have been exemplary. He won the French Open and the U.S. Open and comes into the event as the No. 1 player in the world.

He seems fully healed from knee issues that dogged him in 2012 and he is certainly the man to beat in London.

Novak Djokovic

Djokovic is the defending champion at the event. Without Murray in the bracket, it would seem that he and Nadal are on a collision course for the final. Rafa still owns a 22-16 edge over Djokovic in their lifetime series, but Djokovic is 12-7 against Nadal on hard courts.

If the two men meet in London, you can expect an epic final match to decide the champion.

Sleeper

Stanislas Wawrinka

Wawrinka is just the seventh seed, but he has demonstrated the ability to play with the world's best players. Though he has shown his inconsistency in the last three months, he did reach the semifinals of the U.S. Open after knocking off Murray in straight sets.

He fell to Djokovic in a thrilling five-set marathon, but did make the eventual runner-up sweat.

If he's on his game, he could make some noise.
