CARSON, California – Mario Barrios made sure to give fans what they’re used to seeing at this venue.

Following a completely forgettable lightweight bout between Javier Fortuna and Sharif Bogere, Barrios blew out a game Richard Zamora in the fourth round Saturday night at Dignity Health Sports Park. The taller, stronger Barrios battered Zamora with power shots for much of a junior welterweight fight that was scheduled for 10 rounds on the Gervonta Davis-Hugo Ruiz undercard.

Referee Ray Corona stepped between Barrios and Zamora to stop the action because Barrios blasted a stumbling Zamora against the ropes. Fans booed loudly after Corona halted the action, but Zamora had taken a lot of punishment in three-plus rounds.

San Antonio’s Barrios improved to 23-0 and recorded his 15th knockout in a fight Showtime televised as part of a tripleheader from the venue known until recently as StubHub Center. Mexico’s Zamora (19-3, 12 KOs) lost by knockout for the third time in his six-year pro career.

“I love it,” Barrios told Showtime’s Jim Gray. “He said at the press conference he wanted a war. He got it. He’s a warrior.”

Barrios blasted Zamora with a right hand to the side of his head about 30 seconds into the fourth round. That punishing punch wobbled Zamora, who stumbled backward.

Barrios then viciously assaulted Zamora with head and body shots for much of the rest of the fourth round. Zamora managed to sneak in select shots of his own, but Corona stepped in to save Zamora from himself at 2:16 of the fourth round.

Barrios began unloading on Zamora just under the two-minute mark of the second round. He caught Zamora with a left uppercut and an overhand right near a neutral corner.

Toward the end of the second round, Barrios landed two vicious right hands that shook Zamora.
