The top 4 contenders who can finish the year as the ATP World No. 1

#2 Rafael Nadal

Rafael Nadal

Along with Roger Federer, Rafael Nadal also made his comeback last year at the Australian Open, losing to Federer in an epic five-set final. Since then he has been in great form, winning six titles (including his 10th French Open), accumulating a 67-11 win-loss ratio, and also finishing the year as the World No.1.

He can definitely regain the No. 1 ranking, but the unpredictability of his body always raises doubts. On top of that, he had such a great clay season last year that he has to defend almost 5000 points on the red surface alone.

To put that into perspective, Roger Federer has to defend a total of around 7000 points for the rest of the year. It will be interesting to see how Nadal, or more specifically his body, manages to handle the pressure of the claycourt swing.
