Good ones. Gatti had a few for sure, against Wilson Rodriguez and Ruelas off the top of my head, can't dig much deeper than that.

Leonard against Hearns in the first fight.
OScar De la hoya against Quartery, he needed that huge last round.
Emannuel Augustus against Mickey Ward, fought back after the nasty body shot KD, only to get completely robbed anyways. No way Ward won that fight, the cards were a joke.
Toney against Michael Nunn, it wasn't the sudden one punch eraser people make it out to have been, but Toney was behind for sure and Nunn was very very good.
Hopkins against Pascal first fight maybe, considering he got dropped and was old as dirt already, pretty impressive.
