Arturo Gatti
Mayweather met Arturo Gatti in 2005 in Atlantic City. Given that Gatti had fought wars and had a penchant for leaving it all in the ring, many were eager to see what type of damage he could inflict upon Mayweather. In the first round Mayweather floored Gatti, though the validity of the knockdown was questionable. No matter, because for the next five rounds, the quicker Mayweather tee’d off on Gatti, landing nearly every shot against him. Having seen enough Gatti’s corner stopped the fight after round six, giving Mayweather his third world title.
