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...

There was a big show at The Arena in Monterrey, Nuevo Leon last night with WBC/WBA Super Flyweight Champion Cristian Mijares retaining his belts against challenger Chatchai Sasakul in dominating fashion.

26 year old southpaw Mijares, 36-3-2 (15), who hasn't lost a bout since July, 2002 and held a twelve year advantage in youth against Sasakul, 64-4 (39), beat his Thai opponent to the punch throughout the first two rounds.

By the third frame, the 38 year old ex-WBC Flyweight titlist was getting banged around badly and was stopped at 1:05 of the round after going to the canvas for the second time.

Sasakul had gone 31-1 since losing the WBC Flyweight title to Manny Pacquiao in 1998.

In other bouts on the card, big punching Mexican Middleweight Champ Ruben "Cloroformo" Padilla, 16-2-1 (15), stopped Nicaragua's Wilmer Gonzalez, 16-8-1 (10), in the eleventh of a scheduled twelve round non-title contest.

Undefeated flyweight Koki Kameda, 19-0 (12), posted a twelve round unanimous decision over Salvador Montes, 5-5 (2), to annex the vacant WBA Intercontinental title while former WBC Female Super Flyweight Champ Ana Marie Torres, 16-3-2 (10), came closer to regaining her title by winning the WBC Interim crown against Esmeralda Moreno, 9-4 (3), by ten round UD.
