After a stale first four rounds Berto came alive, chasing Mayweather around the ring with a machine gun jab. Berto's activity allowed him to gain some headway partway through the bout, but in the end it seemed like he was always at Mayweather's mercy.

Bad Left Hook gave Berto a few of his more active rounds, but in the end it seemed like Andre was only able to win rounds that Floyd didn't particularly mind losing. In fact, whenever Mayweather stepped up his own activity and pace he was able to link together some beautiful punches, including the left uppercut that worked so well against Miguel Cotto and the right uppercut to the body that's always been an underrated part of Floyd's arsenal.
In the post-fight interview Floyd insisted that he is in fact retiring from the sport to spend time with his family. He told Jim Gray that he's happy to leave the sport with all of his faculties intact, and mentioned that he is financially stable enough to walk away for good. Time will tell if Floyd can make himself leave behind the sport that he has dominated for so many years, but hey--it wasn't so bad as far as exhibitions go.
