If anyone missed Roger Federer from the clay season, they will be happy to know that the Australian Open champion is all in for the rest of the year.

Back on the court from a two-and-a-half-month break after winning in Miami, Federer is on the Stuttgart grass-courts, prepping for the Mercedes Cup.

The Swiss was interviewed after a practice session.

"No, there's no more breaks now, I've had enough breaks," the 35-year-old said. "I'm a practice world champion now and that's not who I want to be. I want to be a champ on the match courts so...this is what it's about now—playing matches," he said.

Federer has been practicing with 39-year-old Tommy Haas and looks ready to take the grass season by storm.

He'll actually face Haas in his opening round on Wednesday. The two have played each other 16 times, with Federer leading 13-3. The German hasn't defeated Federer since the Halle final in 2012.
