Defeated Berto struck by Mayweather’s IQ in the ring (Reuters)
By Mark Lamport-Stokes LAS VEGAS (Reuters) – For Andre Berto, Floyd Mayweather’s boxing IQ was the most impressive attribute on show at the MGM Grand on Saturday as the five-division world champion ended his professional career with a perfect 49-0 record. Berto, a 30-1 underdog, could do very little against his fellow American as Mayweather once again delivered a consummate tactical display in the ring to retain his WBC and WBA welterweight titles on a unanimous decision. “He’s smart, really smart,” twice former welterweight world champion Berto told reporters after being beaten for a fourth time in his last seven fights to slip to 30-4.
