Diego Pacheco

Diego Pacheco is an American super-middleweight whose combination of size, power and rapid ascent have made him one of the division’s persistent unbeaten hopefuls. Standing 193 cm with a 201 cm reach and fighting from an orthodox stance, Pacheco has compiled a 26–0 record with 19 stoppage victories while holding secondary/regional belts — the WBC Silver and the WBO International super‑middleweight titles (not primary world championships). Pacheco turned professional in December 2018 and quickly established himself as a heavy-hitting prospect. Early in his career he closed many of his bouts inside the distance, with a string of first-round and early stoppages through 2019 that set a knockout tone. As his opposition and schedules stepped up he moved into six‑, eight‑ and ten‑round fights, adding unanimous decision wins and longer fights to his résumé while maintaining a high stoppage rate. A marked progression came in 2022 when Pacheco began campaigning consistently over ten rounds and into regional title territory. He won the vacant WBC‑USNBC super‑middleweight title in September 2022 via fifth-round TKO over Enrique Collazo and defended regional honours later that year. In March 2023 he claimed the vacant WBO International super‑middleweight crown with a fourth‑round TKO of Jack Cullen in Liverpool, the first of a series of successful international assignments. Pacheco has defended his secondary titles multiple times, mixing stoppages and decisions. Notable title defenses include a fourth‑round TKO of Manuel Gallegos in Monterrey and a ninth‑round KO of Marcelo Cóceres at the YouTube Theater. He produced a high‑profile knockout of Maciej Sulęcki in August 2024 — a sixth‑round KO at Dignity Health Sports Park — that underscored his ability to finish at the twelve‑round level. In 2025 and into 2026 Pacheco continued to consolidate his regional standing. He scored unanimous decision victories in 12‑round title fights—including successful defenses in Las Vegas, Frisco and Stockton—before winning the WBC Silver super‑middleweight title on December 13, 2025, while retaining his WBO International belt. On July 18, 2026, Pacheco registered a decisive TKO in the 11th round against Immanuwel Aleem in Carson, California, retaining both the WBO International and WBC Silver straps. Born in Los Angeles and commonly listed as fighting out of Renton, Washington (some records vary), Pacheco remains active and undefeated at 26–0 (19 KOs). His record of regional titles, extended 12‑round experiences and a steady progression in opposition have placed him firmly among the division’s regionally ranked fighters as he continues to build toward bigger tests.
