Boxing-Mayweather beats Berto in ring farewell (Reuters)
(Adds detail) LAS VEGAS, Sept 12 (Reuters) – Floyd Mayweather Jr. cemented his place among the pantheon of boxing greats with a unanimous decision over fellow American Andre Berto on Saturday in what he has repeatedly said would be the final fight of his career. Mayweather, 38, outboxed his younger opponent over the 12 rounds to retain his WBC and WBA welterweight titles and improve his perfect career record to 49-0, matching the benchmark set by former heavyweight champion Rocky Marciano. Five-division world champion Mayweather dominated most of the exchanges in the MGM Grand Garden Arena with his lightning jabs and agile movement about the ring to finish ahead on all three judges’ scorecards.
