Kalkreuth seriously tested by Valera

Tristan Kalkreuth outlasted Felix Valera in a ultra competitive and oftentimes complicated heavyweight clash that ultimately was not reflected as such on the scorecards.

Judges awarded Kalkreuth a unanimous decision victory via scores of 99-91, 99-91, and 97-93, just as Kalkreuth came into the tenth and final round looking to finish the fight definitively to ensure he got the nod.

Kalkreuth landed 121 of 511 of his punches while Valera connected with 113 of 417 of his shots.

The heavy favorite Kalkreuth (15-1, 10 KOs) couldn’t leverage 14 years in youth, a five-inch height and four-inch reach advantages to separate himself from the very game Valera (23-8, 20 KOs), a 37-year-old Dominican coming into the contest after stoppage defeats in two of his last three fights.

The Ronnie Shields-coached Kalkreuth fought past the sixth round for just the second time in his six-year career and looked fatigued and sluggish at times. “Sweet T” hadn’t fought since June, and he’d also gotten married since the last time he stepped in the ring. In February, Kalkreuth, a 23-year-old from Texas, re-signed with career-long promoter Golden Boy.

Kalkreuth, typically a cruiserweight, competed at the heavyweight limit after taking the fight on short notice. He weighed in at 206 ¾ pounds for the 210-pound catchweight clash.

Abdullaev justifies the hype

Super lightweight prospect Ruslan Abdullaev proved why many believe he has a high ceiling and plenty of potential by dominating Jino Rodrigo with a unanimous decision win.

Abdullaev (2-0, 1 KO), a 2024 Olympian representing Uzbekistan, demonstrated great power, speed, movement, and combinations for eight rounds and was rewarded with scores of 80-71 across the cards.

Abdullaev rocked and dropped Rodrigo in the fourth round with a whipping left hook, just as Rodrigo was landing a right hand of his own. Abdullaev went on to wear down Rodrigo with relentless aggression and shots to the body and was pressing for the knockout that never came during the comprehensive beatdown.

Abdullaev outlanded Rodrigo 132 to 24 in the fight.

Abdullaev, a 22-year-old trained by Joel Diaz, made his pro debut in March and scored a second-round knockout against Jose Valenzuela Alvarado before signing a promotional deal with Golden Boy soon after. Abdullaev made his ring walk with fellow countrymen Murodjon Akhmadaliev and Bektemir Melikuziev, proving here that he could be joining them as a contender in the very near future.

The durable Rodrigo (13-5-2, 11 KOs), a 27-year-old from the Philippines, has never been stopped. He came off a first-round knockout against previously-unbeaten Mathew Gonzalez in March after a 10-round decision loss to Elvis Rodriguez.

Iriarte ices Jimenez to open main card

Joel Iriarte (7-0, 7 KOs) barely broke a sweat to blast and stop Marcos Jimenez (25-12, 17 KOs) 104 seconds into the first round of their welterweight fight scheduled for eight.

The finishing blow was a picture-perfect left hook that dropped Jimenez face-first. Jimenez’s corner stopped the contest before referee Sharon Sands could reach the count of eight.

Gvozdyk’s triumphant return

Former light heavyweight champion Oleksandr Gvozdyk got back into the win column by dropping Anthony Hollaway twice and stopping him in three rounds.

Gvozdyk (21-2, 17 KOs) tagged Hollaway (9-7-3, 7 KOs) and dropped him with a left hook 30 seconds into the third round. Hollaway got up but was rattled, and Gvozdyk landed another left hook to drop him once more. The outmatched Hollaway got up once again but referee David Solivan stopped the action at the 1:37 mark of a fight scheduled for eight rounds.

Gvozdyk was fighting for the first time since his unanimous decision loss to David Benavidez in June. The 38-year-old Ukrainian came into the clash calling for a “dream fight” against Callum Smith.

Edwards aces pro debut

Heavyweight prospect and 2024 United States Olympian Joshua Edwards made his pro debut in great fashion, scoring a second-round stoppage win against Larry Gonzales.

Edwards (1-0, 1 KO) connected with a barrage of punches in the second round and knocked out the mouthpiece and busted the left eye of Gonzales, who ill-advisedly had turned southpaw.

Although the 24-year-old, Ronnie Shields-trained Houstonian didn’t drop Gonzales, he did more than enough damage to force the fight to be waved off at the 1:51 mark once the defenseless Gonzales turned his back in the corner.

Chavez stays perfect

Jorge Chavez dominated Brandon Douglas and scored a shutout unanimous decision win via scores of 80-71 across the scorecards in their eight-round junior featherweight fight.

Chavez (14-0, 8 KOs) chopped down the very game Douglas throughout the bout and also dropped him with a left hook in the second.

Douglas (13-2, 11 KOs), a 32-year-old southpaw from Salt Lake City, Utah, sported a respectable record albeit against competition that had a combined record of 65-176-19.

First-round finishes to kickstart the prelims

Super welterweight prospect Samuel Torres Castellanos (2-0) made easy work of Marc Misiura (3-8-1, 1 KO) and scored a first-round stoppage win after Misiura’s corner stopped the fight before the second round got underway.

Lightweight prospect Dalis Kaleiopu (7-0, 5 KOs) kicked off the card and connected with a head-snapping straight hand to knock out Jesus Ramon Perez (14-21-1, 8 KOs) at the 2:23 mark of the first round.
