In the walkout bout of the evening, junior welterweight Abraham Lopez won a four round unanimous decision over Antonio Wattell (1-3, 1 KO). All three judges scored the bout 40-36 in favor of Lopez (3-1-1, 1 KO).

Light flyweight Carlos Licona won a six round unanimous decision over Cesar Sustaita. Licona (7-0, 2 KOs) was the more-accurate puncher, beating Sustaita to the punch during most of the exchanges. Sustaita (3-3, 3 KOs) did find success landing an occasional counter left hook or right cross, but fought defensively during most of the fight. All three judges scored the bout 60-54 in favor of Licona. 

Middleweight Esquiva Falcao stopped Paul Valenzuela in the fourth round. Falcao (14-0, 10 KOs), who won a Silver medal at the 2012 Olympic Games, had his hands full with Valenzuela during the first two rounds. But his pedigree began to show in the third round when he hurt Valenzuela with a left hand to the stomach.

Valenzuela (9-3-1, 6 KOs) dealt with a cut that opened over his right eye in the fourth round, courtesy of a punch from Esquiva. Moments later, a ringside physician examined the cut and deemed it too deep to continue, prompting the fight to be stopped at 1:31.

Austin (29-7-4, 18 KOs) attempted to time Ruiz with right hands to the head, but rarely connected. After the fourth round, Austin's corner informed referee Raul Caiz, Sr. Austin was unable to continue.
