Floyd Mayweather equalled former heavyweight great Rocky Marciano’s 49-0 record with a unanimous decision victory over Andre Berto before promptly announcing his retirement.
Mayweather, who repeated his insistence in the build-up that this bout would be his last, was the heavy betting favourite and unsurprisingly dominated his overmatched foe to retain his WBC and WBA welterweight titles.
Scores of 120-108, 118-110 and 117-111 took the five-weight world champion, almost universally regarded as the pound-for-pound best in the sport, to his 49th consecutive victory in the professional ranks.
Yet the 38-year-old seems to have no desire to reach a half-century as he said in his in-ring interview: “My career is over, that’s official.
“You’ve got to know when to hang it up. I’m close to 40 now. There’s nothing left to prove in the sport of boxing. Now I just want to spend time with my family”
