 Roger Federer has now won two grand slam events |
Australian Open champion Roger Federer and French Open winner Juan Carlos Ferrero have agreed to play in the Hamburg Masters in May. The event was saved from financial collapse last year by tournament chairman Boris Becker.
Federer beat Russia's Marat Safin to take the Australian Open title at the weekend.
The win elevated the Wimbledon champion to the top of the world rankings, while Ferrero is number two.
Federer won in Hamburg two years ago while Ferrero lost in the final three years ago to Spanish compatriot Albert Portas.
Becker said Federer, 22, had promised late last year at a meeting in Switzerland to take part in the �1.6m tournament.
"He is the most complete player on the tour and has now managed to turn his great talent into success," Becker said.
