Last weekend Sergio "Maravilla" Martinez stamped his class for the whole world to see at the expense of the young Julio Cesar Chavez, Jr. in a one-sided boxing clinic. Martinez is considered as the best pound-for-pound fighter by most boxing experts, next to Floyd Mayweather, Jr. and Manny Pacquiao. Many fancy a Martinez-Mayweather match-up at middleweight, but if one were to ask Mayweather's former trainer and estranged father Floyd Mayweather, Sr., he doesn't want any part of it for his son.
