Callum Walsh's clash against Elias Espadas ended anticlimactically but in victory nonetheless as the Irishman won a fifth-round technical decision win Saturday at the Chumash Casino in Santa Ynez, California.

A clash of heads in the second round between the southpaw Walsh (14-0, 11 KOs) and orthodox Espadas (23-7-1, 16 KOs) split open Walsh's right eye with a nasty gash, but the Irishman realized he had time on his hands to end matters on his own terms, especially as his combinations backed up Espadas.

In the end, however, the fight was called off right as the bell sounded in the fifth, and Walsh ended up being rewarded with scores of 50-46 across the board for the super welterweight fight scheduled for 10 rounds.

"I want to apologize … It’s very disappointing to win a fight like this," Walsh said afterward. "I'll put on a show again for you, definitely. It was growing into a good fight, and both of us were enjoying it. It's not the best way to win … I felt the fight was going one sided and in my way. It was going to continue going my way, it's unfortunate. [The cut] impacted my vision and I couldn't really see. But I feel that I did enough [to win]."

Before the third round got underway, referee Rudy Barragan had the ringside physician Tony Hicks inspect Walsh's eye. The same scenario unfolded before the fourth, and the fight ultimately ended in the fifth before a punch was thrown due to the severity of the cut.

As he looks to carry the flag for Zuffa Boxing, Walsh also used the opportunity to accept Fernando Vargas Jr.’s recent challenge and said he would welcome a fight against him on the Canelo Alvarez-Terence Crawford undercard Sept. 13 in Las Vegas.

Walsh-Espadas headlined a 360 Promotions "Hollywood Fight Nights" show on UFC Fight Pass.

In the co-main event, Umar Dzambekov endured the most durable test of his four-year career and outlasted Roamer Alexis Angulo with an eight-round unanimous decision win.

Dzambekov (12-0, 8 KOs) fought through a problematic right eye to stave off the aggressive Angulo (28-4, 23 KOs), gaining incredible experience through victory as the judges awarded the 27-year-old southpaw victory with scores of 80-72, 79-73 and 77-75.

The power-punching Angulo's only losses had come at the highest levels against Edgar Berlanga (UD10) in 2022, David Benavidez (RTD 10) in 2020 and Gilberto Ramirez (UD12) in 2018.

Junior welterweight contender Cain Sandoval (16-0, 14 KOs) caught outmatched late replacement opponent Jonathan Jose Eniz (36-23-1, 17 KOs) in the corner during the second round and unleashed an onslaught to end their scheduled eight rounder incredibly early, as referee Rudy Barragan waved off the action at the 2:31 mark.

Featherweight phenom and surefire future world champion Iyana “Right Hook Roxy” Verduzco (5-0, 1 KOs) competed in her first eight-rounder. She passed another test with flying colors by scoring a unanimous decision win against Celene Roman (6-4-1, 0 KOs), as each of the judges scored the contest 79-73.

Daniel "Chucky" Barrera (9-1-1, 4 KOs) bounced back and returned to the win column by besting Basilio Franco (10-4, 8 KOs) by unanimous decision in an eight-round junior bantamweight bout via scores of 80-72, 79-73, 79-73. Barrera suffered the first loss of his career last time out in February.

Headlining the preliminary portion of the action on YouTube was a bout between Gor Yeritsyan and Vernon Brown, and the welterweight fight delivered the most shocking result of the night.

Yeritsyan was pitching a one-sided shutout through six rounds of their scheduled eight-rounder when Brown found lightning in a bottle and landed a chin-rattling left hook that dropped Yeritsyan midway through the seventh.

Yeritsyan was clearly hurt, never recovered and was seemingly out on his feet for the rest of the round as the southpaw Brown kept piling on unanswered punches, forcing referee David Solivan to step in and stop the action at the 2:46 mark of the round.

The Freddie Roach-trained Yeritsyan (20-2, 16 KOs) would have been well served to take a knee to survive the round and see the final frame, but he got caught in the fire and went up in flames once "Sub Zero" Brown (14-2-1, 10 KOs) iced him for the shocking stoppage win.

Before the seventh round got underway, Solivan had the ringside physician inspect Brown, a 36-year-old from Chicago, due to the quantity and quality of shots he was absorbing. Solivan even gave Brown several hard warnings to "show him something" before the fight-altering punch landed.

Yeritsyan, a 30-year-old from Armenia, came into the clash yearning to make a mark by winning the Zuffa Boxing title, but the loss seriously derailed any championship plans for the foreseeable future.

Kicking off the action on the night was a less-climactic featherweight fight between Jenelyn Olsim (0-0-1) and Jessica Radtke Maltez (1-2-2), resulting in a four-round majority draw.
