Champion or challenger, the approach is the same for Brian Viloria.

That said, the two-time world champ acknowledges his upcoming title shot carries some added emphasis.

"Each fight I treat it the way it’s supposed to be treated, real serious. No different for this one," Viloria said before a workout Friday at Kalihi Gym. "The way I look at it, there’s more motivation for me. There’s a lot of things riding on this fight; a world title, I’m coming into the last few legs of my career. So it’s that much more important for me to do well and win another one."

The Waipahu product’s opportunity at a third world championship comes July 16 when he faces Julio Cesar Miranda of Mexico for the World Boxing Organization flyweight title at Blaisdell Arena.

The fight was originally scheduled for June 4 at the Staples Center in Los Angeles. A change to the card delayed the fight and it was subsequently moved to Honolulu.

"It’s always great to fight back in Hawaii," Viloria said. "Fighting back home is something I always look forward to, especially with guys like these and world titles on the line. It’s an opportunity for me to get back a world title and get back on the throne."

"He’s a world champion. … For him to come out here to my hometown, it’s a lot of credit to my management."

Viloria (28-3, 16 KOs) last fought at Blaisdell on Aug. 29, 2009, when he successfully defended the IBF light flyweight belt with a unanimous decision against Jesus Iribe. He lost the title in his next bout, a TKO against Carlos Tamara on Jan. 23, 2010.

He has since moved up to 112 pounds, where he began his professional career, and defeated Omar Soto last July. He then earned a shot at Miranda’s title by stopping Liempetch Sor Veerapol in the seventh round on Nov. 5 in the Philippines.

Viloria will be in town over the weekend, then return to Los Angeles to complete his training.

He said the delay from the original date hasn’t impacted his preparation other than allowing him time to further study Miranda.

Miranda (35-5-1, 28 KOs) claimed the vacant WBO flyweight title with a TKO of Richie Mepranum on June 12, 2010. He fought all three of his defenses in Mexico, the last on Feb. 26, a TKO of Arden Diale.

"He has a lot of power in his hands and it shows in his record," Viloria said. "He likes to slug it out. I know in hand speed I’m faster than he is. I might be a little more elusive than he is. He likes to stand in the pocket and stay right in front of you and try to bang it out. It makes for an interesting matchup."
