25-year old welterweight gunslinger Pedro Campa (25-0, 19 KO), 141, of Hermosillo, Sonora, Mexico, overcame a few rocky moments to record a brutal fourth round knockout of 30-year old former lightweight title challenger Marvin Quintero (29-8, 25 KO), 141, of Tijuana, Baja California, Mexico.

It was the main event at the Gimnasio Municipal, Guaymas, Sonora, Mexico, on Saturday night.  The referee was Octoviano Lopez.
