12. Diego Corrales TKO10 Jose Luis Castillo, May 7, 2005 – The first nine rounds were incredible, but the 10th is one of the all-time greats. Castillo knocked Corrales down twice early in the round and Corrales seemed like he may not be able to continue. Out of nowhere, he crushed Castillo with a straight right that essentially put Castillo out on his feet. He landed several more shots before referee Tony Weeks jumped in to halt it and give him the improbable win.
