LAS VEGAS (AFP) - 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.

Despite skepticism, Mayweather has insisted throughout the build up to the Pacquiao fight that 49-0 would be enough for him - and he wouldn't be tempted to try for a 50th win.
