Fights where top oppenents got dominated..

[Yes We Can]

Gatti might not have been THE top opponent but he was a top opponent none the less,the opening poster never really said the dominated fighter had to be No1,he used Alexander as his pick and he just got dominated by Porter

Gatti was dominated

Khan and Alexander were of a similar standing,

MAyweather & Gatti were not.

Leonard vs Benitez

I wouldn't say that was domination, Leonard was up by maybe 3-4 rounds at the time of the premature stoppage.
Duran vs. Moore was brutal domination from start to finish.

Roy Jones domination of James Toney.
