Roger Federer overtook Rafael Nadal at the top of the world rankings after beating Milos Raonic on route to winning the title in Stuttgart.
Grigor Dimitrov climbed to the fifth spot while Marin Cilic fell to the sixth. Kevin Anderson remained in the eighth position, ahead of David Goffin and John Isner.
The current ATP rankings and point scores are as follows:
|4.||Del Potro Juan-Martin||Argentina||5080||19|
|8.||Anderson Kevin||South Africa||3635||21|
Roger will need to triumph once again at Halle Open this week if he is to prevent Rafa returning to No.1 in their continuing see-saw battle. Even the runner-up spot and 300 points would see Roger fall 50 points behind our champ.
As the reigning Halle and Wimbledon champion Roger has 2500 points to defend in his two scheduled grass events, whereas Rafa has only 180 points.
Rafa is still #1 in the year-to-date rankings.
