The 28 year-old had too much power and experience for the challenger, 22, and took him out with a flurry that saw referee Vic Drakulich stepping in to save Rivera from further punishment.
‘Big Bang’ Hernandez pushed his impressive record to 29-2-1, 18 KO’s with a seventh successive victory and remains one of the standout fighters of the 108b division today.
In chief support at the Caballerizas de Huixquilucan, former world title challenger Julio Ceja kept himself within touching distance of another title chance with a fourth round win over Jesus Acosta.
The 21 year-old Mexican knockout machine made it 24 stoppages from 26 wins by crushing his compatriot in four one-sided rounds, with ‘Chovy’ dropping to 14-3-2 with a second loss on the spin.
Talented puncher Ceja lost out to Briton Jamie McDonnell on UK soil in 2013 for the IBF bantamweight belt in a closely fought contest, but is widely tipped as a future world champion after claiming the ‘WBN Title Prospect of 2013’ award at the beginning of last year.
