NABF Welterweight champ Saul Alvarez, 27-0-1 (20), kept busy with a ninth round KO of Jeferson Luis Goncalo, 12-4-3 (5), last night at Parque Xcaret in Cancun, Mexico

There was another NABF belt on the line with local flyweight Wilbert Uicab, 25-5-1 (16), seeing off tough Filipino import BJ Dolorosa, 5-2 (0), over ten rounds to retain the title for the second time.

Light flyweight Omar Nino Romero, 28-3-1 (11), scored a technical decision in the eighth against veteran Juanito Rubillar, 46-12-7 (22).

Lightweight Jose Emilio Perea, 15-0 (8), defeated overmatched opponent Juan Pablo Sanchez, 3-1 (3), via second round stopage for the WBC Fedcarbox title.

Jorge Paez Jr, 22-2 (14), stopped Jose Ramirez, 5-2 (5), in the seventh at light welter and ex-WBC light flyweight champion Eric Ortiz, 31-8-3 (20), fought to a six round draw with two-time world flyweight title challenger Gilberto Keb Baas, 28-19-3 (16).

Two massive fight cards took place on Saturday night in Mexico and first, we'll examine what took place at Auditorio Guelaguetza in Oaxaca as there were three world titles on the line.

Mexico City's Erik Ramirez, 25-6-1 (19), stepped up to challenge WBO Minimumweight Champion Donnie Nietes but the WBO Latino titlist was canvassed in the first, fifth, ninth and twelfth frames yet somehow managed to finish the fight on his feet, only to lose a 116-108, 115-109 and 113-111 points decision.

Nietes, of Bacolod City, Philippines, improves to 24-1-3 (14) by winning his 11th straight and retaining the WBO belt for the second time since defeating previously unbeaten Pornsawan Kratingdaenggym for the crown in September, 2007. More...

Lots of action south of the border this weekend and we start with a big show at Palacios de los Desportes in Mexico City where Edgar Sosa retained his WBC Light Flyweight title for the fifth time by stopping southpaw Takashi Kunishige in the eighth round on Saturday night.

Kunishige, 18-3-1 (2), came into the contest not having lost in over five years and drew with Japanese champion Munetsugu Kayo last time out but facing the WBC Champion proved to be a step too far for the 32 year old from Osaka.

It's a testament to the Japanese visitor's toughness that he lasted as long as he did against the superior skilled Mexico City man but his run came to an end when Sosa forced a referee stoppage at 1:39 of the eighth frame after dealing out much punishment.

On the undercard, NABF Flyweight titlist Adrian Hernandez, 13-0-1 (11), was held to a fifth round technical draw by challenger Eric Ortiz, 28-8-2 (18), a former WBC Light Flyweight Champion.

OPBF Light Flyweight strapholder and Filipino southpaw Juanito Rubillar, 46-10-7 (22), won a WBC title eliminator against Omar Nino Romero, 25-3-1 (11), via a 12 round split decision. More...
