LAS VEGAS - Floyd Mayweather earned a unanimous decision over Manny Pacquiao on Saturday and reaffirmed his plan to retire after his next bout in September. "My last fight is in September. I'll do that and I will hang it up," vowed the unbeaten American, who took his record to 48-0 with his win over Pacquiao in their much anticipated welterweight clash. With one more fight, the 38-year-old Mayweather will fulfill his rich six-fight deal with telecaster Showtime. And with one more victory he would match the iconic 49-0 ring record of Rocky Marciano. –AFP
