In a flyweight unification bout, Brian Viloria stopped Hernan Marquez in the 10th round at the Sports Arena in Los Angeles, CA. 

Viloria (32-3, 19 KOs) scored a knockdown at the end of the first round. The knockdown seemed to affect Marquez as he did not press the fight, as Viloria continuously landed right hands to the head. 

After Marquez (34-3, 25 KOs) found success early in the fifth round, Viloria would drop Marquez later in the round with a left-right combination. Marquez came on aggressively during the seventh through ninth rounds, scoring more than in the previous rounds. 

However, Viloria dropped Marquez again in the 10th round with another left hook to the head. Marquez was being repeatedly hit to the head, prompting his trainer Robert Garcia to throw in the towel to save his fighter from further punishment. 

Referee David Mendoza stopped the fight at 1:01. 

With the victory, Viloria successfully defended his WBO title and captured the WBA title.

In one of the best fights of 2012, Roman "Chocolatito" Gonzalez won a hard-fought 12 round unanimous decision over Juan Francisco Estrada.

Gonzalez swept the first three rounds, but Estrada came on in the fourth round, at times backing up the 108 lb. champ. Gonzalez controlled the middle rounds, constantly finding a home for a right hand to the head or left hook to the body.

Undaunted, Estrada came on in the final rounds, producing a great ebb and flow between himself and Gonzalez.

Both fighters had their moments in the final round, but Gonzalez was able to get the nod on all three judges' scorecards, 116-112, 116-112, and 118-110. krikya360.com scored the bout 116-112 for Gonzalez, who successfully defended his WBA light flyweight title.

Welterweight prospect Rodrigo Garcia stopped Octavio Narvaez in the second round of a scheduled six round bout.

The taller and stronger Garcia (12-0, 7 KO) rained down punches onto the stockier Narvaez, who tried to get on the inside. In the second round, Garcia landed four right hands in succession to the head of Narvaez (7-13-1, 4 KOs), dropping him to the canvas. Referee Dr. Lou Moret immediately stepped in and stopped the bout at 1:54.

Super bantamweight Drian Francisco stopped Javier Gallo in the fifth round of a scheduled eight round bout.

The southpaw Francisco (23-1-1, 18 KOs) was effective with his awkward style, outlanding Gallo to the head. He was especially effective landing counter left uppercuts to the head of Gallo. Although Gallo (18-6-1, 10 KOs) landed right hands to the head of Francisco, his punch output dropped due to the Filipino fighter attacking his body. In the fifth round, Francisco aggressively attacked Gallo, hurting him to the body with hooks and left hands.

After Gallo staggered backwards after a series body punches by Francisco, referee Dr. Lou Moret stepped in and stopped the fight at 2:54.

Welterweight Andy Ruiz won a hard-fought four round unanimous decision over Rufino Flores. Ruiz, who is trained by Robert Garcia, was quicker to the punch in the first round, but was momentarily stunned by Flores in the second. The 19-year old Ruiz (4-0, 2 KOs) was able to control the tempo by landing hard right hands to the head of Flores (2-5, 2 KOs). All three judges scored the fight in favor of Ruiz, 39-37, 39-37, and 40-36.
