|Group A||Group B|
|Novak Djokovic||Roger Federer|
|Andy Murray||David Ferrer|
|Tomas Berdych||Juan Martin del Potro|
|Jo-Wilfried Tsonga||Janko Tipsarevic|
Novak Djokovic and Andy Murray are the class of Group A, and should each be able to survive the round-robin stage.
Jo-Wilfried Tsonga has played well all season, but he has not been able to defeat Tomas Berdych recently and he is simply not consistent enough to defeat either of the top players in the group.
Djokovic and Murray have each handed each other their most recent loss, and that rivalry should continue in this tournament.
The difference is, Murray seems to perform better on a bigger stage, which means he has a better chance of faltering before the semifinals.
Prediction: 1. Djokovic 2. Murray 3. Berdych 4. Tsonga
Roger Federer has been great in almost every tournament he has played in over the years, but this year-end championship has been his specialty.
He has won here six times, finishing with an undefeated record in five of those tournament victories.
Only once since 2002 did he fail to reach the semifinals, and that will not change this year.
Juan Martin del Potro has been on an amazing run lately and should be able to continue his good play toward a berth in the knockout stage. Meanwhile, David Ferrer is not as good away from clay and Janko Tipsarevic has struggled lately.
Prediction: 1. Federer 2. Del Potro 3. Ferrer 4. Tipsarevic
Juan Martin del Potro should give Novak Djokovic all he can handle, but the Serbian will be able to win with his great ability to break serve.
On the other half of the bracket, Roger Federer should be able to avenge his loss to Andy Murray at the Olympics. This should be a very emotional match with the English crowd, but the No. 1 player in the world has the experience to end up on top.
Prediction: Djokovic def. del Potro, Federer def. Murray
The match that most people around the world want to see will take place in the final, with Djokovic taking on Federer.
Federer might move a little slower than he has in the past, but he still can place the ball as well as anyone in the world. He has dominated this tournament over the years and really wants to keep his No. 1 world ranking.
No one, including Djokovic, should be able to take it away from him.
Prediction: Federer def. Djokovic
