It wasn't pretty but WBC middleweight champ Sergio Martinez kept his title against England's Martin Murray last evening in front of over 40,000 people Club Atletico Velez Sarsfield in Buenos Aires, Argentina.

The stadium was packed for the fighting return of Martinez for the first time since 2002 and the 38 year old switch-hitting southpaw had brought in the third English opponent he's faced since 2011, former British, Commonwealth and current WBA Interim champ Murray.

Early on, Martinez looked like the Sergio of old, using shifty movement, hands-down defense and punches from odd angles to keep Murray looking stiff and unsure of how to proceed.

But Martinez could keep up the charade of youth for long and soon Murray found himself closer to the target and began to warm to the task at hand.

Murray's hard-nosed approach, which included use of the head and forearm, was in sharp contrast to the elegant style of Martinez, but the older man was unable to hurt the challenger and keep him off.

Slowly, the control of Martinez began to slip as Murray started to throw combinations behind a high guard, landing right hands; Martinez still uses a reaction-based defense, no-hands defense but no longer has the quickness to avoid some of the lunging punches he attracts. More...

One of the world's top light flyweights was in action last night as John Riel Casimero kept hold of his IBF crown against challenger Luis Alberto Rios at Megapolis Convention Center in Panama City, Panama.

Casimero, 18-2 (10), is no stranger to fighting in his opponent's back yard and that's just what the 23 year old from Cebu City, Philippines did last evening, outpointing Panama City man Rios, 18-2-1 (13), also 23 years of age, over 12 rounds.

Despite having the local audience behind him and coming into the bout on the heels of an IBF eliminator stoppage over Felipe Salguero, Rios was unable to

over come the experience and skill advantage of Casimero, who handily outboxed the challenger by scores of 119-109, 119-109 and 118-110.

Retaining his title for the first time, Casimero is at the high point of career that has seen him win the Interim IBF light flyweight belt against Cesar Canchila in 2009, lose it a year later by split decision to Ramon Garcia Hirales and then get stopped by Moruti Mthalane in five for the IBF flyweight strap in 2011.

Undaunted, "Quadro Alas" regained the Interim IBF light fly title in 2012 by stopping Luis Alberto Lazarte in ten before capturing the full IBF trophy in August of that year with a split decision against challenger Pedro Guevera. More...

Second time around proved to be the charm for super featherweight Argenis Mendez, who knocked out Juan Carlos Salgado last night to claim the IBF title at The Hangar in Costa Mesa, CA.

The pair initially tangled over the vacant IBF strap in September, 2011, with Mendez losing a point in the fifth before he dramatically canvassed Salgado in the 12th and final frame, but it wasn't enough as Salgado won a unanimous decision.

Since winning the belt, Mexico City based Salgado had mixed fortunes, retaining against Miguel Beltran Jr by No Contest, scraping by Martin Honorio by majority decision and most recently, posting a wide points verdict over Jonathan Victor Barros this past August.

Dominican born New Yorker Mendez emerged from the first Salgado bout by winning a tune up contest before defeating Honorio on points to win an IBF eliminator in July.

Using the Honorio fights of both Mendez and Salgado as a measuring device proved to be quite accurate as it was clear from the first bell that Mendez was there in Costa Mesa to do the business.

Mendez was clearly the better boxer last night, finding the target right away, dropping Salgado in the opening round. The champion beat the count and lasted out the round as Mendez was unable to better his work. More...

Nonito Donaire turned in yet another superb performance as the "Filipino Flash" retained his WBO super bantam crown with a stunning third round KO of former champion Jorge Arce at the Toyota Center in Houston, TX.

The battle of highly decorated multi-weight world champions had been highly anticipated with the mobility and power of Donaire pitted against the heart and pressure of Arce.

That scenario played out exactly once the bell rang with Arce, a former WBO/WBC light fly, WBO bantam and super bantam titlist looking for a way inside against the taller Donaire, who has held the IBF/IBO flyweight, WBC/WBO bantam and IBF super bantam.

The first frame was fairly uneventful, with the boxers feeling each other out, trying out various strategies but nothing much developed.

In the second, Arce tried to close distance with reaching jabs and wide power shots which were easily avoided by Donaire, who was able to counter with crisp shots that were clearly felt by the Mexican veteran.

A combination head clash and punch exchange caused Arce to be counted for a knockdown in the second but the Los Mochis man beat the count and rode out the remainder of the round. More...

Big super bantam clash tonight in Houston, TX as WBO kingpin Nonito Donaire puts his belt on the line against Mexico's fiery fan favorite and former WBO titlist Jorge Arce at the Toyota Center.

Donaire, 30-1 (19), has been busy in 2012, winning the vacant WBO crown with a split decision over Wilfredo Vasquez in February, a points title defense against Jeffrey Mathebula in July and then a dominating stoppage defense against Toshiaki Nishioka in October.

Arce, 61-6-2 (46), has also had three appearances this year, starting off with a fifth round KO of Lorenzo Parra in a rematch in February, a two round no decision against Jesus Rojas in June and a ten round unanimous decision over Mauricio Martinez in August.

Donaire will have a lot of advantages going into tonight's fight; youth, speed, power, height and reach. The one area that Arce could have an edge in is the heart department.

But, in order to prove that he has the greater will to win, Arce will have to show that he can take Donaire's heavy artillery as the Mexican will no doubt be getting hit early and often.

Arce definitely won't be there to try and outbox "The Filipino Flash", so in order to come out of this contest with possession his old WBO title, he'll have to use educated pressure, getting inside and putting Donaire on the defensive but at the same time avoiding getting nailed on the way in.

The king of Luna Park was back in action last night as WBO super fly champion Omar Andres Narvaez returned to the famed Argentinian fight venue in Buenos Aires for the first time in over a year to stop Mexican challenger Johnny Garcia.

Little known Garcia came into the contest with a history of winning regional title clashes but was just two bouts removed from a second round destruction at the hands of one of the divisions rising stars and current WBC Silver boss, Carlos Cuadras.

Going against the masterful southpaw Narvaez, with a combined 20 defenses of the WBO super fly and flyweight titles, was going to be a major step up for the 24 year old from Ciudad Nezahualcoyotl.

Garcia, however, came to fight and immediately went to work, pressuring the 37 year old champion from the first bell. But success didn't always come from the Mexican's efforts as Narvaez continued to display perhaps one of the games best defenses.

Still, the challenger did get home some shots although by the midway point of the contest was beginning to tire. This is what Narvaez had been waiting for as the Cordoba legend went to work, mounting an offense that decked Garcia in the seventh. More...

Josesito Lopez jumped out of obscurity earlier this year by pounding out a surprise win over Victor Ortiz but the 28 year old Californian may just have been slammed back into the land of the lost by WBC light middleweight champion Saul Alvarez tonight at MGM Grand Garden Arena in Las Vegas.

Lopez, until a year ago a light welterweight, stepped up to welter in June to break the jaw and will of former WBC 147 pound belt holder Oritz but the quick jump to 154, in the form of Mexico's Alvarez, proved to be too much, too soon.

The shorter, stocky champion dispensed with any formalities halfway through the first round, banging through with good punches as Lopez tried to read the style of the champion.

The challenger went on the attack in the second but when Alvarez tired of being defensive, his short inside punches rocked Lopez before a spearing shot to the midsection put the American on the canvas at the end of the round.

Lopez was floored again by another body shot soon after the third stanza commenced and once back on his feet, was unable to keep pace with the brisk inside game of Alvarez.

The fourth saw Alvarez open up his arsenal and hit the challenger nearly at will while Lopez showed courage to keep trying in the face of greater talent but was again down on the floor at the end of the round. More...

The Sun Bowl in El Paso, TX played host to a WBC middleweight title clash last night between champion Julio Cesar Chavez Jr and challenger Andy Lee.

The occasion marked the third straight time Chavez Jr has defended his title in Texas since winning the WBC belt against Sebastian Zbik a year ago.

Lee had campaigned long and hard for a title shot and the lanky Irish lefty had been facing a steadily increasing level of opposition but to date had been nowhere near sharing the ring with a world class operator.

The first frame saw southpaw Lee establish distance and score with the jab as Chavez Jr, tried unsuccessfully to get inside. Chavez Jr stepped it up in the second, applying pressure and getting closer as Lee tries picking off the champion.

By the third, Chavez had managed to get close enough to start ripping shots to Lee's body while the challenger looked for openings but had a hard time catching the champion cleanly.

Chavez managed in the fourth to get Lee to start fighting although the Irishman had some success in doing so. The fifth saw some clowning from both fighters as Lee made a concerted effort to dig in and get in the trenches, effectively trading hard shots with Chavez. More...

WBC featherweight king Jhonny Gonzalez retained his title for the fourth time by turning back former champion Elio Rojas on Saturday night at Grand Oasis Resort in Cancun, Mexico.

Gonzalez went into the clash sporting a string of knockout victories but Rojas proved to be capable of handling the power shots of the champion, providing Gonzalez with his stiffest title challenge to date.

The challenger looked to be controlling the action by the third round until Gonzalez changed tactics and began to box, reasserting his authority by the fight's midway point.

Gonzalez cemented his hold on the bout in the tenth when he floored Rojas with a body shot but that just spurred the challenger to give his best effort in the final round. More...

The Grand Oasis Resort in Cancun, Mexico hosts a big night of fights this evening with two world titles on the line.

Big punching featherweight Jhonny Gonzalez, 51-7 (45), meets Elio Rojas, 23-1 (14), in what should turn out to be a barnburner for as long as it lasts.

A former WBO bantamweight champ, Gonzalez failed to win a world title at super bantam but struck gold at featherweight with an IBO title win against Jackson Asiku in 2010 before annexing the WBC crown with a shocking four round dismantlement of Hozumi Hasegawa in Tokyo in 2011.

The busy banger from Mexico City turned away challengers Tomas Villa, Rogers Mtagwa, Roinet Caballero later that year and will be making his first appearance of 2012 when the bell rings this evening in Cancun.

Rojas, originally from the Dominican Republic but now residing in the US, held the WBC feather strap from 2009-2010, winning the title in Tokyo from Takahiro Ao before posting a wide points verdict over Guty Espadas Jr seven months later. More...

The scene last night at Polideportivo Centenario in Los Mochis, Mexcio was a happy one for WBC lightweight kingpin Antonio DeMarco after the lanky southpaw was successful in his maiden defense against challenger Miguel "Mickey" Roman.

DeMarco came into the contest bearing three straight victories following his punishing loss to KO artist Edwin Valero for the WBC strap in 2010, the most recent of which netted the Tijuana native the vacant WBC belt with an 11 round stoppage of ex-two weight world champ Jorge Linares. More...

WBC featherweight king Jhonny Gonzalez kept hold of his title with a commanding performance against challenger Roinet Caballero last night at Centro Banamex in Mexico City.

Caballero, of Panama, came into the bout having gone 22-3 over the last seven years and had previously mounted a failed bid to unseat WBA featherweight champ Chris John in 2008.

Gonzalez brought far more big fight experience in the ring, having engaged in ten prior world title bouts during his reigns as WBC feather, WBO bantam and IBO feather champ along with unsuccessful attempts at the WBC super bantam belt.

Caballero represented the third challenge to Gonzalez's WBC strap, as the Mexico City man had already halted Tomas Villa and Rogers Mtgawa earlier this year after shocking Japan's Hozumi Hasegawa in April to win the title. More...

Big night of boxing south of the border with three fight cards on tap, two of which boasted world title bouts.

WBC light middle ruler Saul Alvarez solidified his hold on the green belt with the biggest won of his career, stopping former IBF welter titlist Kermit Cintron in the fifth round at Monumental Plaza de Toros in Mexico City.

The older, more experienced Cintron tried to pressure young gun Alvarez in the first but landed little of substance as the champion was just too quick and began to effectively counter.

The challenger boxed from a distance in the second frame and had a better round as a result, scoring with the jab and the odd right hand while Alvarez landed a few counters but looked less confident than in the first.

The third saw Cintron stop boxing and look to land bigger shots, which allowed Alvarez to regain control as the challenger's efforts left openings for the champion to exploit.

In the next frame, the fighters started to trade toe to toe with Alvarez successfully finding a home for the left hook to the body of Cintron. More...

On Friday evening, Panamanian featherweight Celestino Caballero went into the lion's den of Buenos Aires' famed Luna Park Stadium to take the WBA title from Argentina's Jonathan Victor Barros in a rematch.

Two years after outgrowing the WBA and IBF super bantam titles, 35 year old Caballero was coming off two split decision losses, the second of which was a WBA title bout against Barros in July.

In that contest, which took place in Barros' hometown of Mendoza, Argentina, the local man was dropped twice but still managed to win two of the three cards.

Barros lost a bid for the WBA crown in March of last year against Yuriorkis Gamboa but when the title became vacant in eight months later, the 27 year old won it by halting Irving Berry before going onto to record successful defenses against Mickey Roman and Caballero. More...

The vacant IBF super flyweight title was on the line last evening at Auditorio Municipal in Tijuana, Mexico with Rodrigo Guerrero emerging victorious in a thrilling rematch against Raul Martinez.

The pair had faced each other in November of last year in an IBF title eliminator with Martinez winning a 12 round split decision.

Southpaw Guerrero proved difficult from the start last night, using shifting stances and giving the shorter Martinez a variety of problems to solve. More...
