Garcia promised to deliver one of his best performances against the WBC welterweight champion in the main event of "The Ring: High Stakes" on Saturday at T-Mobile Arena on DAZN PPV.

“Ferociousness,“ Garcia told The Ring on Wednesday. “A great fight [and a] masterclass and Ryan Garcia classic. Trust me when I say that. You’ll remember this as a Ryan Garcia classic.”

The undercard features a pair of 140-pound world title bouts, with IBF champion Richardson Hitchins facing Oscar Duarte and WBA titleholder Gary Antuanne Russell making the first defense of his belt against Japan’s Andy Hiraoka.

Garcia (24-2, 20 KOs) enters the clash off an upset unanimous decision defeat to WBA welterweight champion Rolando “Rolly” Romero on May 2. The 27-year-old from Victorville, California, will be in his second fight at welterweight and seeking his first win since 2023, when he knocked Duarte out in the eighth round.

As a full-fledged welterweight, Garcia said there's a difference between this camp and when he faced Romero.

“It’s a complete [180],” he said. “Things were done in order [and] done right. This is what it should feel like before a fight — confident and prepared and ready to do my job.”

Barrios (29-2-2, 18 KOs), 30, is making the third defense of his belt. The San Antonio native is coming off back-to-back draws, with the latter coming July 19 vs. former eight-division champion Manny Pacquiao. Garcia’s former trainer, Joe Goossen, will be in Barrios’ corner for the first time. Garcia and Goossen went 2-1 together.

While Garcia insisted the fight isn’t personal, he also said a win would have a little more meaning beyond being his first world title.

“It makes it that much more satisfying when I do win,” Garcia said. “Especially that whole squad, I know they really think they're gonna do something. It's one of those things when you're playing your own teammate, or you're facing your brother, and you just want to whoop their ass a little bit more.”
