Dylan Capetillo knocked out by Juan Carlos Becerril in third‑round upset

Seventeen‑year‑old Dylan Capetillo, a Golden Boy Promotions lightweight prospect, suffered his first professional defeat on August 1, 2026. In a four‑round bout at The Theater at Virgin Hotels in Las Vegas, Capetillo led early and even knocked down his opponent in the second round. However, Juan Carlos Becerril of Tijuana landed a decisive left hook in the third round, sending Capetillo to the canvas. Referee Thomas Taylor halted the contest at 2:59 of round three, awarding Becerril a technical knockout.

The loss drops Capetillo to 2‑1 (1 KO) and gives Becerril, who improved to 3‑0 (2 KOs), the biggest victory of his short career. The bout, part of the Roach Jr. vs Zepeda card, highlights the risks young fighters face even in early professional outings.
