Roger Mayweather, he was a Latin fighters assasin in his prime heydays at 130 and 140 lbs. where he won world titles beating many from south of the border as Sammy Serrano, Jorge Alvarado, Benedicto Villablanca consecutively by KO in world title fights in one stretch, Mario Martinez, Sammy Fuentes Rene Arredondo and Gato Gonzales also by KO/TKO separately also in title bouts.

But he never could beat the one Mexican fighter that matter---Julio Cesar Chavez who stopped him at 130 and later 140.

The Black Mamba had 35 KOs in his 59 career wins but also lost almost half (6) of his 13 defeats by KO, falling to Chavez twice, Freddie Pendleton, Rafael Pineda, Ray Lovato and Rocky Lockridge ( KO1). He also fought and lost to Pernell Whitaker and Kostya Tzsyu.

Unlike his great nephew, Floyd Jr.. Roger took on all comers at 130 and 140, winning most fights by scary KO/TKO while losing some also by spectacular KO/TKO.

I once read Kieran Mulvaney refer to Roger Mayweather as the "lightweight Tommy Hearns" b/c of his frame and the fact that he hit so hard/his chin was bad.

I FOUND OUT ITS RODGER MAYWEATHER!

HE HITS FREAKING HARD, HOW DOES HIS STRAIGHT RIGHT COMPARE TO HEARNS STRAIGHT RIGHT?
