Jermall Charlo stops Wilky Campfort on eye injury, Errol Spence, Jr. beats down Alejandro Barrera on NBC

The A-sides on this afternoon's PBC on NBC in Dallas faced little difficulty as Jermall Charlo, Errol Spence, Jr., and Erickson Lubin all scored stoppages.

Charlo absolutely dominate "Silky" Wilky Campfort, dropping him three times and ultimately busting something important in the latter's eye. Charlo (23-0, 18 KO) controlled the fight from the outset with his jab and accurate combination punching, scoring the first knockdown of the fight in the second with one of said jabs. Campfort (21-2, 12 KO), who never really got started, went down again on an uppercut in the third, then a final time in fourth on another uppercut. He made it to his feet, but informed the ref that he could not see, ending things.

Nothing unexpected, really. Campfort was a weak opponent, but at least Charlo put him away.

Apparently, we needed two swing fights this time around, as Texan super lightweight Ryan "Cowboy" Karl faced Ken Alvarez in a wonky slopfest. Karl  (11-0, 8 KO) dropped Alvarez (7-3-2, 3 KO) in the first thirty seconds with a left hook and the fight proceeded to devolve into a brawl. Alvarez's utter lack of footwork become readily apparent as he repeatedly crossed his feet with no provocation, resulting in him flopping about the ring.

Despite this, he was still in there with Karl and landing some solid shots of his own. He was pushed down in the third for a called knockdown, but kept on slugging until the fifth of six scheduled rounds. A right cross sent him stumbling down once more and, though he seemed alright, his corner made the decision to stop the bout.

Sorry, Jim Ross. I'm just not seeing a bright future for "Cowboy."

The co-main saw former Olympian Errol Spence, Jr. roll on with a fifth-round TKO of Alejandro Barrera in a fight recently upgraded to IBF title eliminator.

Spence (19-0, 16 KO) came out aggressive as usual, working behind the jab and landing solid blows to the head and body. He first got to Barrera (28-3, 18 KO) with a right hook in the second round and built momentum from there. Barrera, though game, struggled with his foe's speed and combination work, giving up more and more ground as the fight progressed.

Spence turned things way up in the fifth, storming forward and absolutely wrecking Barrera's body. A nasty right hook in the corner sent him to a knee and Spence never let up, pummeling a broken-looking Barrera until he took a knee and Lurence Cole stepped in.

If there's a knock on Spence's performance, it's that he got tagged more than most would prefer int he opening rounds. Barrera found success with his right uppercut and right straight.

With the afternoon's first fight ending in just over three minutes, the broadcast added a super lightweight bout between 23-year-old super lightweight prospect Eddie Ramirez and Bilal Mahasin. Despite a spirited effort by Mahasin, Ramirez's body work and power carried him to a unanimous decision.

Mahasin (7-2-1, 1 KO) found some success in the mid-to-late rounds with volume and pressure, he didn't manage to overcome the early deficit or nullify Ramirez's (12-0, 8 KO) consistent thumping to the gut. Ramirez seems like someone worth keeping an eye on, provided he can tweak his ringcraft to avoid finding himself on the ropes so often.

In the opening bout, hot super welterweight prospect Erickson Lubin had zero trouble with latest victim Alexis Camacho, sending him down for the count in two. In the first round,"The Hammer" (13-0, 10 KO) rattled Camacho (21-6, 19 KO) with a right  hook-left straight, then sent him to a knee with another right hook. It wasn't the hardest knockdown, but the next one was, as Lubin pasted Camacho with a counter right in the opening seconds of the next round.

Camacho seemed out on impact, but woke back up after a second, making the decision to stay down a reasoned one.
