Myung Woo-Yuh against Oh Kon Son. Incredibly courageous performance from Son who stood up to an awful beating for seven rounds, in which he hit the deck multiple times before the referee finally took mercy on him (which he or the corner should have done way earlier). Son's bravery was so that he'd have kept going if he could, but Yuh absolutely belted the living daylights out of the poor lad. The McGirt-Warren rematch, too. Once again, nothing but admiration for Warren's courage but Buddy absolutely brutalised him in a sustained manner. Got to mention Barrera against Paul Lloyd, too. Unlike the others this wasn't a sustained, long beating because his corner retired him after a single round, but it says a lot about how embarrassingly one-sided it was that they felt they had no other option after a mere three minutes of action!
Mando Ramos v Chango Carmona Chango Carmona v Rodolfo Gonzalez In both instances the loser went out of the ring on a stretcher.
Holmes vs. Ali was hard to watch. And, if it had been scheduled for 12, it very well might have gone the distance that way.
The worse one sided beat down. ( Not including devastating and dominate early KO' s Like Hearns vs Cuevas/Duran or Sanchez vs Gomez) Is in my opinion Holmes vs Cobb. Cobb didn't win a minute of a 15 rd fight. Think about that for a minute.
Archie Moore vs Jimmy Slade. Moore made target practice of him. He was just making money to have a bit of fun and try some stuff on a live body. Jimmy was tough though but man was it cool to see such a “Young” Archie Moore.
You think a fight where the eventual victor was knocked down belongs in the discussion of "worst one sided beatings EVER?" one-sided would imply the other guy has no moments at all
Marco Antonio Barrera vs Mzonke Fana: Brutal KO in a mismatch of a great champion vs an unheralded mandatory challenger. I remember an outcry after the fight to re-examine mandatories and ranking systems
