9. Felix Trinidad RSF4 Luis Ramon Campas (1994)
56-0 with 50 stoppages before the fight, Mexico’s Campas was a dangerous challenge for welterweight champion Trinidad.
He dropped the champion in the second, who responded with a series of low blows resulting in a point deduction.
After some furious work on the inside, Trinidad snapped Campas’ head back with a sickening blow and referee Richard Steele ended proceedings.
