Yeah, that was the most recent. Before that, the biggest shut outs :
Barrera/Hamed
Mayweather/Gatti
Hopkins/Trinidad
Calzaghe/Lacy
Yeah, I mean...did anyone EXPECT Diaz to win a round? I doubt even Diaz expected it.
Calzaghe-Lacy, forgot about that one. Excellent performance in a big fight.
Toney-Holyfield also comes to mind. And though many wouldn't say it was one-sided, Toney-Jirov is another.
a few of mayweathers performances have been absolutely godlike, especially corrales cos it was one of the only times he was fighting a live oppoenent in a pick 'em (although an argument could be made for the hatton fight as well).
Also, surprised no one has mentioned this : Winky vs Tito That was a domination of epic proportions, unbeleivable performance and display of defensive boxing, absolutely incredible.
