Berto ‘on a mission’ to unseat Mayweather (Reuters)

By Mark Lamport-Stokes LOS ANGELES (Reuters) – Andre Berto will go into his welterweight title fight against Floyd Mayweather in Las Vegas next week as a heavy underdog but also as a man “on a mission” as he bids to end his fellow American’s perfect 48-0 record. Berto, 31, he has blinkered himself from all the hype and hoopla that usually surrounds the build-up to a Mayweather bout and claims he has never been fitter as he prepares to step into the ring at the MGM Grand Garden Arena on Sept. 12. “I’ve had a tremendous training camp, a long camp but a tremendous camp,” twice former welterweight world champion Berto told reporters on a conference call on Tuesday.
