Wasn't Yaqui Lopez a Mexican?? (or NATIVE American Indian?) either way he wins in a landslide. That dude was a solid fighter, that went thru his whole career with ****ty luck, and never catching a break:-(
He had a number of title shots and I believe Network TV appearances, so he had plenty of breaks compared to most fighters, he just could not get his hands on a world title.
Of those not mentioned yet, I kinda HATE to say it but - Ayala Jr. at least deserves mention. Disgusting human being, but had talent. Woulda beaten the Hell outta Canelo, I know that.
You shoulda been more specific and said fighers FROM Mexico. Ayala WAS of Mexican descent and Donald Trump would sure as Hell consider him a Mexican.
