Floyd Mayweather Jr. on Tuesday announced he has signed a six-fight deal with Showtime, which will televise his May 4 welterweight title fight against Robert "The Ghost" Guerrero at MGM Grand in Las Vegas on pay-per-view.

Mayweather, 36 this Sunday, had fought all of his big bouts on HBO as well as its pay-per-view arm. According to YahooSports.com, Mayweather rejected a multi-fight deal from HBO to sign with Showtime and its parent company, CBS.

Mayweather and Oscar De La Hoya hold the record of 2.5 million viewers for their May 2007 fight on HBO pay-per-view.
