Undefeated Bantamweight Colombian and Los Angeles transplant Oscar "Jaguar" Negrete (16-0, 6 KOs) will square off against Sergio "El Frio" Frias (18-6-2, 9 KOs)at Fantasy Springs Resort Casino in a 10-round main event for vacant NABF Bantamweight Championship in the June 30th edition of Golden Boy Boxing on ESPN. This marks the 50th show that Golden Boy Promotions has put on at Fantasy Springs. After Randy "El Matador" Caballero and Jesus "Estrella" Ruiz went down to injury, Negrete will now face a fighter in Frias who is coming off a knockout of former world champion Vic "Raging Bull" Darchinyan. In the newly announced co-main event, super lightweight contender Ryan "Blue Chip" Martin (18-0, 11 KOs) of Chattanooga, Tennessee will bring his unblemished record to the desert in a 10-round fight against Marcos "El Tigre" Jimenez (22-7, 15 KOs) of Santo Domingo, Dominican Republic. Hoping to make TV, heavy-handed Genaro "El Conde" Gamez (4-0, 3 KOs) from San Diego, California, returns to Fantasy Springs for the first time since knocking an opponent clear out of the ring last September. This time, he will take on Miguel Barajas (2-2, 1 KO) from Guadalajara, Mexico in a six-round match-up of lightweights.
