Mayweather: "The best thing about my career is the sweet science, hitting and not getting hit..."

Floyd “Money” Mayweather (48-0, 26 KOs) opened up the Mayweather Boxing Club for his last media day ever as he prepares for the last fight of a celebrated 19-year career. He will defend his WBC and WBA Welterweight World Championships against power-punching, two-time welterweight world champion Andre Berto (30-3, 23 KOs) .
If triumphant, Mayweather would match the record of the late heavyweight champion Rocky Marciano, who retired in April 1956 with a record of 49-0.
