Floyd Mayweather to retire after beating Andre Berto

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.
