The following list gives credit to "The Man Who Beat The Man." NY recognized Jockey Joe Dillon as
Junior Flyweight champ in the 1920s.
The modern 108-pound class was created in 1975 and for some time was referred to pejoratively as the "Diaper" class. Early title claimants of note included
Luis "Lumumba" Estaba,
Yoko Gushiken, Hilario Zarate, and
Myung-Wuh Yuh. Yuh vacated his title in 1993, while
Michael Carbajal defeated Humberto
"Chiquita" Gonzalez. Carbajal, therefore, is the first undisputed Junior Flyweight world champion.
