Waipahu boxer Brian Viloria wants to remember the Alamodome as one of the greatest fights of his career.

Viloria will face Mexico's Edgar Sosa for the World Boxing Council light flyweight championship Saturday at the Alamodome in San Antonio, Texas.

Viloria is 19-1 and ranked No. 1 by the WBC. Sosa is 26-5 and ranked No. 2.

"I don't know if Brian's ever been more motivated for a fight," said Team Viloria manager Gary Gittelsohn. "He really wants to recapture his title, and you'll see a really focused, a really determined Brian Viloria in the ring."

Viloria held the championship before losing it to Omar Nino via decision last October.

In a rematch for the belt in November, Viloria and Nino fought to a controversial draw, and Nino tested positive for methamphetamine after the bout. The WBC stripped Nino of the title and made it vacant. The draw was also declared a no-contest.

In an effort to regain the championship, Viloria has been working with a new trainer, Joe Goossen, in Van Nuys, Calif.

"Brian's talent and skills have never been a problem," Gittelsohn said. "But there were times when we'd scratch our heads because he'd look unbeatable in one fight, then not look nearly as good in the next fight.

"That won't be a problem with Joe Goossen. Joe is a terrific motivator."

Goossen said he started Viloria with the basics, and then made daily progress for the past two months.

"We did a lot of drills, over and over, just like in football or baseball," Goossen said. "And then we took it in the ring and did a lot of sparring."

Goossen said Viloria completed an estimated 150 rounds of sparring over the past two months in preparation for Sosa. What's more, Goossen used various boxers — ranging from 105 pounds to 120 — to trade practice blows with Viloria.

"There were days we'd go 15 rounds," Goossen said. "Brian will not fade in this fight, I can tell you that. His conditioning is to a point where he's a machine right now."

Still, it won't be easy. Sosa has won his last 14 bouts, and his last loss came in 2003. Gittelsohn described Sosa's style as "rangy."

"He's probably not going to want to trade (punches), so Brian will have to put some pressure on him," Gittelsohn said. "Brian will have to be at his best, and that's what we're expecting."

Saturday's bout will be part of a pay-per-view event, featuring Manny Pacquiao and Jorge Solis in the main event.
