Seventeen-year-old Dylan Capetillo, the highly-touted lightweight prospect and son of renowned cutman Jorge Capetillo, suffered his first professional boxing loss on Saturday, August 1, 2026.
Juan Carlos Becerril of Tijuana delivered a shocking technical knockout (TKO) in the third round of their scheduled four-round bout at The Theater at Virgin Hotels Las Vegas, handing Capetillo a significant early career setback.
Upset on the undercard: Capetillo’s early lead evaporates
Capetillo, known as “La Amenaza,” had initially controlled the fight, showcasing the skills that led Golden Boy Promotions to sign him. He even floored Becerril in the second round, building an early advantage on the scorecards.
It looked like the Las Vegas native was heading for another victory in just his third professional outing. But Becerril, entering the fight with a 2-0 record and two knockouts, refused to be deterred.
The momentum dramatically shifted in the third round. Becerril landed a crushing left hook that sent Capetillo to the canvas, stunning the young American. Though Capetillo managed to beat referee Thomas Taylor’s count, his legs were visibly unsteady.
Taylor promptly halted the contest at 2:59 of the third round, awarding Becerril the TKO victory. This unforeseen turn of events marked a significant upset on the “Roach Jr. vs. Zepeda” card.
A promising professional boxing career hits first hurdle
Dylan Capetillo’s professional journey began just months earlier, in April 2026. He had secured a first-round TKO victory against Jesus Antonio Rios Castro in his debut at The Cosmopolitan in Las Vegas.
His second fight, on May 2, 2026, saw him earn a unanimous decision against James William Pierce. That bout took place on the high-profile David Benavidez vs. Gilberto Ramirez undercard at T-Mobile Arena.
These early wins built a 2-0 (1 KO) record and considerable anticipation around his burgeoning talent. He was introduced to boxing at eight, training at the family-run Capetillo Boxing Gym.
His impressive amateur career included three WBC amateur championships. By age 14, he had amassed 52 wins in 60 amateur contests and was ranked second nationally, clearly destined for Tyson Fury’s career path.
Jorge Capetillo’s influence and the weight of legacy
Dylan’s deep connection to the sport stems from his father, Jorge Capetillo, a highly respected figure in boxing. Jorge is widely known as a premier cutman and trainer in the professional ranks.
He gained international recognition for his crucial work in Tyson Fury’s corner during the 2019 fight against Otto Wallin. Fury suffered a horrific cut above his eye, which Jorge expertly managed, allowing the “Gypsy King” to continue and secure a career-defining win.
Fury later acknowledged Jorge Capetillo’s vital role with a bonus. He even used Jorge’s Las Vegas gym for preparations before his rematch with Deontay Wilder.
This familial background meant Dylan grew up immersed in elite boxing circles, learning from champions like Canelo Alvarez, Manny Pacquiao, and Tyson Fury since childhood. This exposure shaped his early development.
However, it also means his performances, both triumphs and setbacks, often come with an added layer of scrutiny. The boxing world watches closely when a family name carries such weight.
Undercard results: Zepeda and Muratalla claim victories
The Capetillo-Becerril bout was part of a robust fight card promoted by Golden Boy Promotions. The main event saw William “El Camarón” Zepeda (33-1, 27 KOs) clinch the vacant WBC lightweight championship.
Zepeda defeated Lamont “The Reaper” Roach Jr. (25-1-3, 10 KOs) by unanimous decision, with judges scoring the fight 117-111, 117-111, and 118-110. This was a significant title fight headlining the TNT Sports series.
In the co-main event, Raymond “Danger” Muratalla (24-0, 17 KOs) successfully defended his IBF Lightweight World Championship. He secured a unanimous decision over Robson “O Brabo” Conceição (21-3-1, 10 KOs), winning with scores of 118-110, 118-110, and 119-109.
Other notable undercard action included Charles “Bad News” Conwell (21-1, 16 KOs) stopping previously unbeaten Paul Kroll (12-0-2, 8 KOs) in the ninth round of their super welterweight clash.
Raul “El Cugar” Curiel (17-0-1, 14 KOs) earned a majority decision over Quintin “QuickDraw” Randall (17-3-1, 4 KOs). Meanwhile, Joel Iriarte (11-0, 10 KOs) defeated Jorge Lagunas (19-10, 16 KOs) by TKO at 2:48 of the eighth round.

The night also featured Dalis Kaleiopu (9-0, 7 KOs) delivering a spectacular first-round knockout against Yeyery Castillo (14-3, 11 KOs) at 2:37 of the round. Promotional mergers often highlight the dynamic nature of such fight cards.
What’s next for the young Capetillo after this setback?
A fighter’s first loss, especially early in a career, can be a defining moment. For Dylan Capetillo, still only 17 years old, this defeat offers a valuable, albeit painful, learning experience.
Many legendary careers have endured early setbacks before reaching championship status. It will be crucial for Capetillo and his team, led by his father Jorge, to meticulously analyze the fight.
They’ll need to identify areas for improvement and continue his development, focusing on resilience and mental fortitude. Golden Boy Promotions, known for nurturing young talent, will likely guide him carefully through this period.
Their investment in his potential means one loss at such a young age is rarely a career-ender. The lightweight division remains intensely competitive, with a mix of seasoned veterans and rising stars all vying for dominance.
Capetillo will need to demonstrate his resolve to bounce back from this upset. Such fight analyses often focus on how young boxers respond to adversity.
His next fight will be keenly observed to see how he responds to this adversity. This moment marks a true test of character in the unforgiving world of professional boxing, an unexpected twist in his journey.
The psychological impact of an early career upset
For any athlete, particularly a promising young boxer like Dylan Capetillo, an early career defeat carries significant psychological implications. The pressure to maintain an unbeaten record is immense, especially for those highly touted by major promoters.
However, true growth often emerges from such challenging experiences. Overcoming adversity, learning from mistakes, and re-entering the ring with renewed determination can forge a stronger, more disciplined boxer. This unexpected loss compels Capetillo and his team to reassess their strategy.
They must focus on fundamentals and develop effective strategies to counter aggressive, resilient opponents like Becerril. This upset also underscores the inherent depth of talent on undercards, where every fighter is striving for their breakthrough moment.
Becerril’s unwavering refusal to yield and his ability to capitalize on a dramatic shift in momentum highlight boxing’s unpredictable nature. No professional contest, regardless of the perceived favorite, is ever a guaranteed outcome.
Ultimately, this defeat is not necessarily a derailment for Capetillo’s career trajectory. Instead, it serves as an unexpected detour, forcing a period of introspection and refinement. How he processes this experience and applies its lessons will undoubtedly define the next chapter of his burgeoning boxing journey.
