ARLINGTON, Texas – Errol Spence Jr. wasn’t the only heavy-handed, vicious southpaw at AT&T Stadium on Saturday night.

Mexican bantamweight Luis Nery knocked down McJoe Arroyo once apiece in the second and third rounds, and twice in the fourth round on his way to a technical-knockout victory. Sensing their fighter had no shot to get back in this one-sided bout, Arroyo’s handlers mercifully told referee Laurence Cole to stopped the fight following the fourth round.

Nery’s win was the second of three fights FOX Sports aired as part of the Errol Spence Jr.-Mikey Garcia pay-per-view undercard from the Dallas Cowboys’ AT&T Stadium.

Tijuana’s Nery (29-0, 23 KOs) extended his knockout streak to 10. Puerto Rico’s Arroyo (18-3, 8 KOs) lost by knockout for the first time in his eight-year pro career.

Nery, 24, won for the third time since losing the WBC bantamweight championship on the scale a year ago. The WBC stripped Nery of its 118-pound title last February 28 because he was three pounds overweight for his rematch with Shinsuke Yamanaka in Kokugikan, Japan.

Nery stopped Yamanaka in the second round of their second bout, but he still left Japan without his title.

On Saturday night, Nery simply overpowered a fellow southpaw who couldn’t keep a superior puncher off of him. Nery pressed forward, unloaded hard left hands to Arroyo’s head and body, and never appeared worried about what Arroyo threw back at him.

Nery’s left hand knocked down Arroyo with a left hand when there were about 50 seconds to go in the second round. Arroyo reached his feet and fended off Nery long enough to make it to the third round.

A right hand to the body by Nery floored Arroyo in the third round, but he again survived to the end of it. Nery then knocked down Arroyo twice late in the fourth round.

Nery’s victory ended quickly enough that FOX aired a swing bout before super middleweights David Benavidez and J’Leon Love came to the ring.

In that bout, unbeaten Mexican junior welterweight Lindolfo Delgado knocked down James Roach twice with body shots in the first round and scored a first-round, technical-knockout victory.

Roach (5-2, 5 KOs), of Grove, Oklahoma, twice went down from left hooks to the body. As he tried to get up from the second knockdown, referee Mark Calo-oy realized he shouldn’t continue and stopped their scheduled six-rounder with one second to go in the opening round.

The 24-year-old Delgado has knocked out each of his nine professional opponents.
