In a fierce battle of southpaws, Filipino Joebert Alvarez scored a stunning 6th round TKO victory over Jonathan “La Bomba” Gonzalez to win the WBO North American Boxing Organization and FECARBOX  flyweight title in Puerto Rico.

The trainer of Alvarez, Nonito “Dodong” Donaire Sr, father/trainer of five division world champion and reigning WBO super bantamweight champion Nonito “The Filipino Flash” Donaire had predicted in a conversation with The Standard prior to the fight that he expected Joebert to win.

He told us Joebert was “looking good in training” at his Boxing and Fitness Gym in Oakland, California.

In an overseas telephone conversation with us, “Dodong” Donaire said Alvarez dropped Gonzalez in the 2nd round but suffered a cut and told the referee that it was caused by a head-butt and he was “worried about the cut” but the referee claimed it was caused by a punch.

He said Alvarez “kept on pressuring Gonzalez and they began exchanging punches but Joebert was much stronger.”

Donaire Sr said the 24 year old Gonzalez who was ranked No. 6 by the IBF and had a record of 18-1-1 with 12 knockouts suffered his only loss at the hands of former world champion Giovanni Segura by a 4th round TKO on August 17, 2013 because of overconfidence  while Alvarez’ only loss was a hugely controversial ten-round decision to WBO/WBA flyweight champion Juan Francisco Estrada in Sonora, Mexico on December 6, 2014 .

He said promoter “Toto” Zabala plans to put Alvarez on a card in Redwood, California on July 9.

Gonzalez was coming off a ten-round split decision win over Carlos Ruben Dario of Argentina on October 16, 2015  after beating Miguel De Valle in a rematch on May 16, 2015 in Puerto Rico when Del Valle retired in the 2nd round of a scheduled ten-round bout after Del Valle dropped an 8th round unanimous decision in their first meeting.

Gonzalez was an outstanding amateur boxer and  won two out of three memorable bouts with Olympian McWilliams Arroyo and was Puerto Rico’s national champion in 2008, 2009 and 2010.

Joebert won the vacant WBC Continental Americas title with a unanimous ten round decision over Juan Rivera on April , 2013 after earlier winning the WBO Asia Pacific light flyweight Interim title with a knockout of countryman Jerry Domogdan.
