Gotta be Corrales-Castillo I, one of my favourite fights ever.
Marquez-Diaz was a good comeback as well, I think JMM has to be the best at coming back in fights.
The obvious Tyson-Douglas.
Some that aren't quite the same because they didn't win the fight, but JMM in the first Pacquiao fight was an amazing show of heart, and Andrade-Bute would of been one of the great comebacks, although it was spoilt by Marlon B. Wrong, but still ranks there for me.
Also Mosley-Mayorga would of been there, except for the fact that the judges were scoring it terribly for Mosley. Most fans had him needing a knockout going into the final round
