Mexican-American boxer Diego Pacheco officially challenged Jaime Munguía following his knockout victory in the eleventh round over Immanuwel Aleem in California.
Diego Pacheco defeated Immanuwel Aleem by knockout in the eleventh round and, still in the ring, challenged the WBA super middleweight world champion, Jaime Munguía. The fight took place at the Dignity Health Sports Park in Carson, California, where the Mexican-American retained the WBC Silver belt and claimed the WBO International title.
A knockout that opens doors
Pacheco, aged 25, now boasts an unbeaten record of 26-0, with 19 victories by knockout. In his latest fight, he dominated Aleem from the first round until closing the bout in the eleventh. “I have a lot of respect for Jaime Munguía. He is someone I admired since I was a child. I remember being in Mexico watching him win his first world title at 154 pounds,” the fighter stated after the match.
The challenge is not a coincidence. According to BoxRec, Pacheco ranks fourth in the world super middleweight rankings and is the highest-ranked American in the division. His rise has been steady since his professional debut in 2018, and this year he has already fought three times, all victories.
The promoter sees a mega event
Eddie Hearn, Pacheco's promoter, did not hesitate to label a potential fight against Munguía as a “mega event”. “Is there any fight better than Diego Pacheco against Jaime Munguía for the super middleweight world title? That would be a mega event here,” Hearn noted, who is already planning his protégé's return for November.
For his part, Jaime Munguía, with a record of 46-2, recently became world champion last May against Armando Resendiz. The Tijuana native, who has been champion at 154 and 168 pounds, would have the opportunity to face a young and ambitious challenger who has already sparred with Saúl Álvarez.
What does it mean for the fans?
For boxing fans, a fight between Pacheco and Munguía would be a generational clash. Pacheco represents the new blood, while Munguía is an established veteran. Both are Mexican or of Mexican descent, which adds a component of national pride. If it materialises, the fight could take place in the first quarter of 2026, likely in the United States or Mexico.
The unbeaten Pacheco will have to wait for Munguía's response, but his performance over the weekend makes it clear that he is ready to make the leap. In the meantime, the public can follow the progress of both fighters in the coming weeks when negotiations are officially announced.
