Federer makes successful injury return

Monaco - Roger Federer made a successful return following knee surgery, beating Spaniard Guillermo Garcia-Lopez 6-3, 6-4 in the second round of the Monte Carlo Masters on Tuesday.

Federer hadn't played since losing to top-ranked Novak Djokovic in the Australian Open semi-finals in late January and arthroscopic surgery Feb. 3 for torn cartilage in his left knee.

He was scheduled to play at the Miami Masters two weeks ago but pulled out because of a stomach virus.

In sunny conditions, Federer looked untroubled before a rare blip saw him broken at love serving for the match at 5-2. But he concluded his straight-set victory by winning his next service game.

Earlier, Andy Murray overcame some sloppy serving to beat Pierre-Hugues Herbert 6-2, 4-6, 6-3 to reach the third round.
