All the blood and sweat dripping down Brian Viloria’s face after 12 rounds of boxing was well worth it.

The Waipahu High School alumnus became the sixth Filipino to win a world title in multiple weight divisions, earning a unanimous decision over Julio Cesar Miranda on Saturday night in the main event of Island Assault 2 at the Blaisdell Arena.

Although the scores were misread in the ring, the finally tally was 117-110, 114-113 and 115-113 in favor of Viloria, who won the World Boxing Organization flyweight title.

The Star-Advertiser scored the bout 114-113 in favor of Viloria, who improved to 29-3 overall and 5-3 in world title fights.

His previous two title reigns came as a light flyweight. Miranda had a five-fight winning streak snapped, falling to 35-6-1 overall.

"I’ve wanted this since last year, when I lost my (IBF light flyweight) world title," Viloria said. "I wanted to get back on the horse and I did tonight."

Viloria took control of the fight immediately, scoring the only knockdown of the fight in the first minute.

A right cross sent Miranda to the canvas in the first round in his second consecutive fight.

"I didn’t want it to excite me too much because I knew Miranda has a lot of power in his punches," Viloria said. "I felt his power tonight."

This time, Miranda couldn’t recover from the early knockdown, as Viloria stayed on the offensive, opting to engage in a slugfest with his Mexican foe.

Miranda controlled the early moments of the second round, but Viloria later battled back with hard shots to Miranda’s body.

After slugging with Miranda for much of the next two rounds, Viloria spent most of the fifth on the move, scoring with jabs from the outside.

Viloria ended the sixth by pinning Miranda against the ropes and landed a left to the head just before the bell. Another body shot knocked Miranda into the ropes early in the seventh and Viloria connected on several combinations that appeared to have Miranda in trouble.

But Miranda battled back and Viloria showed some swelling above the right eye in the eighth.

Viloria excited the crowd by landing three solid rights in the ninth, but Miranda kept coming, and both survived the 12th to send the decision to the judges with Viloria, bloodied but standing, winning on all three cards.

Viloria remained undefeated in Hawaii, winning his fifth professional fight in his hometown.

"Miranda has got balls, because Brian hit him with some shots that would have knocked most people down," Team Viloria manager Gary Gittelsohn said. "I had it 116 to 113 in favor of Brian, but I might be a little biased."

Miranda, who struggled to make the 112-pound weight limit on Friday, said it played a factor in his performance.

He had to cut more than 2 pounds in 3 hours to avoid being stripped of the title.

"The long flight and the losing of the weight had a lot to do with (me) not fighting well," Miranda said through a translator. "It’s why (I) would like a rematch."

Viloria made $25,000 for the fight.
