Was this the biggest win for Mexico Boxing?

I personally think it is...

Aside from the ones already mentioned Mexico has had some great wins especially in the golden era.
Zurita has 2 great wins. 1 over Sammy Angott & 1 over Sixto Escobar.
Kid Aztecas first win over Ceferino Garcia was special. I believe he was the underdog coming into fight.
Baby Casanova holds a win over Henry Armstrong.
Macias defeating Songkitrat was astronomical and just put him as a household name.
Olivares defeating Rose at the Forum was out of this world at the time.

But none of those come close to what JMM just did.

And Armstrong was robbed in the Garcia fight.
