MGM Grand, Las Vegas - WBA junior flyweight champion Roman Gonzalez (30-0, 25KOs) promised to make a statement in his American debut, and he made good on his word. After a dominating first round, Gonzalez unleashed an uppercut up the middle to put Omar Soto (22-9-1, 15KOs) down for the count in the second.

Rising welterweight prospect Yoshihiro Kamegai (19-0, 17KOs) stopped a very game Hector Munoz ( 19-5-1, 12KOs) in the sixth round.

Super middleweight Hiromitsu Miura (9-0, 3KOs) won a six round unanimous decision over Hector Hernandez (10-5-2, 4KOs). In the first round, Hernandez was rocked and fell into the ropes, but he never went down. Miura suffered a bad cut, which may have happened from a clash of heads in the fourth or fifth round, but he outworked his opponent for a clear win.

Middleweight Carlos Linares (9-1, 8KOs) dropeed Kevin Riding (3-3-1, 0KOs) in the opening seconds of the first round, and then a moment later Linares battered him in the corner until the referee stepped in to wave it off. Carlos is the brother of Jorge Linares.

In his Top Rank debut, undefeated super bantamweight Chris Martin (23-1-2, 6KOs) lost a shocking ten round split decision to journeyman Jose Angel Beranza (34-21-4-2, 26KOs). The scores were 97-93 for Martin, 98-92 for Beranza, and 96-94 for Beranza. Martin looked very sluggish in the contest and he allowed Beranza to outwork him in way too many rounds.
