Mario Barrios appears on Prime Video to announce he’s changing trainers and to discuss his February 21 welterweight title defense against popular contender Ryan Garcia in what will be Garcia’s third title shot.

Barrios says the “intangibles” make the Las Vegas bout an intriguing event following consecutive draws versus Abel Ramos and Manny Pacquiao.

Barrios announces he’s leaving trainer Bob Santos for Hall of Fame cornerman Joe Goossen, who formerly trained Garcia.

“Knowing what he brings as a trainer, we can do big things,” Barrios said.

Goossen said they’ve been training for two weeks.

“We’re working on perfection right now,” with sparring to start in a couple weeks, Goossen said.

Barrios said there will be Voluntary Anti Doping Association testing for the bout following Garcia’s positive tests for the banned PED ostarine to cause a no-contest after Garcia knocked down three-division champion Devin Haney three times last year. 

“Ryan will follow through in the right way,” Barrios said. "I don’t think there’ll be anything to worry about."
