The Whittaker-Hurtado one does come to mind, I remember somebody on HBO, maybe Lamps, talking about how when you could literally wind up with your left hand over and over again then the other guy's probably not in good shape.

There's been a lot of them though, this thread made me remember this fight with Carlos Quintana on ESPN 2 before Cotto, I think it was at the Playboy mansion, can't remember who it was against but just remember thinking hell man what is this referee waiting on. Can't remember who he was fighting though.
