Federer sends out Wimbledon warning

Roger Federer kept his Wimbledon dream on course with a 6-3 6-1 4-6 6-1 third-round victory against Mardy Fish which should serve as a warning to the likes of tournament favourites Andy Roddick and Andre Agassi.

Federer is the real deal – a player who has won more matches than any other on the ATP tour so far this year and who won his fourth title of the season and his first on grass in Halle last week.
