Chavez - Martinez round 12. Haven't been that afraid a fighters 12 rounds of hard work would be undone in the final minute for a long, long time. The fact Martinez went balls to the wall, dropped his hands and traded & refused to hold after the knockdown just made it that much more epic.
Chavez vs Martinez the 12th Pac vs Marquez 4 round 5 was up there too Rios vs Alvarado was amazing just cant remember a specific round that leaped out from the others Im sure Adamek vs Walker had a round that could be up for nomination
That round takes the cake. Round 5 of pac marquez was good but it probably doesn't even crack the top 10. We've had a very good year of boxing.
Up for consideration... Salido-Lopez II Round 9 Viloria-Marquez Round 5 Rios-Alvarado Round 5 Guerrero-Berto Round 7 Ademeck-Walker Round..2, I believe Marquez-Pacquiao Round 5 Martinez-Chavez Round 12 I'm certain that there are a bunch we're missing.
