That is interesting that by the time I typed my previous post, the two posters before me posted the two that I thought of. Good stuff.
Hagler-Hearns rd 1 (For TWO extremely skilled fighters going toe to toe for 3 minutes) Corrales-castillo I rd 10 (for the drama, and the outcome of the round and fight) Gatti-Ward I rd 9 (for the simple sheer bruteness of two men savagely trying to kill each other.)
Best Round 1 ever... Especially based on the lead-up to the fight.... You could tell this fight wasn't goin to the judges. After that Round, they probably sent them ****ers home...
