Castillo I by far. Maidana I was pretty close up until the championship rounds, Chino let off the gas. Seemed he gassed out.
Castillo was a clear win, he beat Void and everyone knew it. Watch Oscar fight Void, Oscar land much more, but Void's judges gave a split decision for Void, and this was after Oscar was over the hill.............Pac stopped Oscar, Void could not come near doing such....................
Oscar was drained to death,Floyd atleast fought Oscar at 154.the 147 fight with Pac was ridiculous,and it was even older Oscar. Oscar had name,same as Ali against Holmes,and nobody sane gives Holmes any credit.
I can see this as well, Castillo is/was considered the best LW in a generation, and gets underrated a lot. During both fight's he was able to do some great bodywork and effectively force Mayweather out of his comfort zone. Maidana is more of a mauler not giving an inch, he made it a real street fight and showed no respect to his defense or skill. I think on average I score the Castillo fight's closer(usually get 7-5 PBF every time), while with Maidana how you look at some swing rds can drastically change the fight.
Castillo-Mayweather 1 is the only legitimate claim someone can make that Mayweather has lost a fight. Any other fight is just someone trolling.
