Top 15 KOs in boxing history

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. (Photo credit: Getty)
