In an upset, tough but unheralded Robinson Castellanos (22-11, 13KO) forced former world champion Yuriorkis Gamboa (26-2, 17KO) to not come out for the eight round of a scheduled lightweight ten.
Castellanos of Celaya, México, was the aggressor for the majority of the fight, stalking Miami’s Gamboa by way of Guantanamo, Cuba, and scoring a hard right hand from different angles almost at will. A straight right in the 3rd sent Gamboa down for the first time in the bout. Despite with a little over of the round left, Gamboa was able to survive the round but early in the fourth Castellanos scored another a right, an overhand one, to drop Gamboa again.
Gamboa seemed to get his footing and boxed well for the next couple of rounds but Castellanos kept coming forward and pressuring the Cuban. After a busy finish in the seventh where Castellanos scored a hard body shots to the body, Gamboa decided to not come out for the 8th giving Castellanos the TKO victory.
The bout marked the second fight for Gamboa under the Golden Boy Promotions banner.

Trading away in the fourth Lopez was down a second time from a Rojas right as his nose was busted. Lopez was on his toes using the jab, however, Lopez was down a third time from another right hand as he got up, Rojas continued to attack as referee Tony Weeks stepped in to stop the fight at 1:47 of the eight round.

Dallas, Texas, super lightweight Vergil Ortiz Jr (5-0, 5KO) kept his undefeated intact with a fourth round TKO stoppage of Angel Sarinana (7-6-2, 3KO) of Durango, Mexico, in a scheduled four.

Sarinana did nothing more than survive for the second and third round and it was in the fourth Ortiz Jr landed a hard right hand that finally sent Sarinana down. The tough Mexican fighter beat the count but third man in the ring, Jack Reiss, still stopped the bout.
