Andres Cortes delivered on his promise to annihilate Genesis Servania on Saturday night.

Cortes overcame a flush right hand by Servania and knocked Servania unconscious just as the first round ended on the Joshua Franco-Andrew Moloney undercard at Hard Rock Hotel & Casino in Tulsa, Oklahoma. Cortes wobbled Servania with a right hand and followed with a left hook that left Servania underneath a bottom rope, unable to continue.

Referee Jack Reiss counted to five before realizing that the Filipino veteran couldn’t continue.

Las Vegas’ Cortes upped his record to 15-0 and produced his eighth knockout. Servania (34-3, 16 KOs), who now fights out of Japan, lost by knockout for the first time in 12 years as a pro.

In the bout before Cortes’ quick knockout, Albert Bell didn’t do anything spectacular, but he thoroughly out-classed Julio Cortez in their eight-round lightweight fight.

Bell boxed well, closed Cortez’s right eye with his jab and easily out-pointed the Ecuadorian veteran. The shorter Cortez never stopped trying, but Bell’s defense made it difficult for him to land clean shots on his elusive opponent.

Bell beat Cortez by huge margins on all three scorecards, as each judge scored it a shutout for Bell, 80-72.

The 28-year-old Bell, of Toledo, Ohio, improved to 19-0 (6 KOs). Cortez fell to 15-3 (11 KOs).

Bell built a huge lead by the final round, when a desperate Cortez was in obvious need of a knockout.

A right-left combination by Bell wobbled Cortez with just over 30 seconds left in their fight. Bell’s defense was terrific again in that final round as well.

Bell hammered away at Cortez’s body in the final minute of the seventh round. He also caught Cortez with right hands up top toward the end of the seventh round and built on his huge lead.

A stiff jab by Bell knocked Cortez backward with just over a minute remaining in the sixth round, when Bell let his hands go more than he had done in previous rounds. Bell’s right uppercut caught Cortez with about 20 seconds on the clock in the sixth round.

Bell’s left hook knocked Cortez off balance just after the midway mark of the fifth round.

A right-left combination by Bell stopped Cortez from coming forward with 35 seconds remaining in the fourth round. Bell otherwise dictated distance with his jab and made Cortez miss for much of the fourth round.

A left hook by Bell landed with just under 1:10 on the clock in the third round. Bell continued to control the distance in that round as well.

Bell belted Cortez with an overhand right with just under 1:20 to go in the second round. Cortez pressured him again in the second round, though Bell maintained his composure and tried to work off his jab.

Bell boxed throughout the first round as an aggressive Cortez came forward. Cortez connected with a hand with about 45 seconds remaining in the first round, yet he mostly missed with his power shots in those first three minutes.

In the first fight on Saturday’s undercard, Abraham Nova’s comeback from a 13½-month layoff wasn’t exactly easy.

Filipino underdog Richard Pumicpic hurt Nova toward the end of the first round and tested him at times later in their eight-round lightweight fight. Nova overcame those struggles, however, to beat Pumicpic by unanimous decision.

The 27-year-old Nova, of Albany, New York, remained undefeated (20-0, 14 KOs) in his first fight since suffering a torn Achilles’ tendon last year. Nova boxed for the first time since he defeated Philadelphia’s Avery Sparrow (10-3, 3 KOs, 1 NC) by unanimous decision in their 10-rounder in June 2020 at MGM Grand Conference Center in Las Vegas.

Judges Karen Holderfield (79-73), Mike Ross (79-73) and Greenwalt (78-74) scored Nova a convincing winner over Pumicpic. The 31-year-old Pumicpic is 1-4 in his past five fights and 22-12-2 overall, including seven knockouts.

Though Nova had some shaky moments, Pumicpic seemingly needed a knockout by the final round to pull off an upset. It was Nova, however, that landed the more effective punches in those final three minutes.

Nova connected with a right hand just before the midway mark of the eighth round.

Nova worked well off his jab during the seventh round. He also made Pumicpic miss with most of shots in those three minutes.

Another left hook by Pumicpic impacted Nova and backed him up with just over 30 seconds to go in the sixth round.

Nova controlled the action in the fourth round, but Pumicpic drilled him with back-to-back right hands barely 30 seconds into the fifth round. Nova fired back with a right-left combination several seconds later, which got Pumicpic’s attention and made him retreat.

They traded hard shots just before the fifth round ended.

Pumicpic extended his glove toward Nova early in the third round. Nova ignored that gesture and belted Pumicpic with a left hook that knocked him backward.

Nova landed a right hand with about 45 seconds to go in the fourth round. Pumicpic went down a couple seconds later, but it was ruled a slip because their legs got tangled.

A left-right combination by Pumicpic early in the second round was effective, though Nova didn’t seem hurt by it.

Nova got off to a slow start in the opening round. Pumicpic caught Nova with a flush left hook that wobbled Nova just before the end of the first round.
