BRIAN Viloria remained unbeaten in his ring comeback after scoring a fifth round technical knockout win over Miguel Cartanega on Saturday at the Stubhub Center in Carson, California (Sunday, Manila time).
The 36-year-old Fil-Am pounded on his hapless American opponent midway through the fifth round, which prompted referee Raul Caiz Sr to wave off the fight.
Viloria, the former two-time world champion currently on the comeback trail, raised his record to 38-5, with 23 KOs.
Early this year, he scored an eighth-round unanimous decision win over Ruben Montoya.
Cartanega, from Philadelphia, fell to 15-4-1 with 6 KOs. He was visibly hurt by Viloria in the fourth round, but the native of Waipahu, Hawaii failed to deliver the coup de grace.
The scheduled eighth-round bout was part of the undercard of the Srisaket Sor Rungvisai-Roman Gonzales rematch for the World Boxing Council super-flyweight title.
The reigning champion from Thailand won the action-packed bout behind a sensational fourth-round knockout of Gonzales, once widely considered as the undisputed pound-for-pound fighter in the world.
The rematch came six months after Rungvisai dethroned Gonzales, the hard-hitting puncher from Nicaragua, behind a majority decision win in a fight that saw the Thai scored a first round knockdown against Chocolatito.
In another exciting fight in the undercard, Juan Francisco Estrada eked out a close, unanimous decision win over tough Carlos Cuadras. Estrada, a two-time world champion, all won by scores of 114-113. Ring announcer Michael Buffer mistakenly announced Cuadras as the winner, but quicky corrected himself and declared Estrada as the clear winner. Estrada earns an automatic shot at challenging for Ruvingsai's title.
