Mexican flyweight Ángel Ayala Lardizabal, popularly known as “Cameleon,” secured a dominant victory over Jayson Mama of the Philippines on Thursday, May 21, 2026. The main event of the IBA PRO 18 show at Arena CDMX in Mexico City concluded in the fifth round when Ayala Lardizabal landed a pinpoint liver shot that left the man known as “The Smasher” unable to continue. The event, co-promoted by the International Boxing Association (IBA), Zanfer Boxing, and Zignia Live, showcased the rising Mexican star’s power before a raucous home crowd.
The victory moves the 26-year-old Ayala Lardizabal to a professional record of 19-1 with 8 knockouts. Jayson Mama, 28, saw his record slip to 21-4-1 following the stoppage. While Mama attempted to use his counterpunching skills early in the bout, he struggled to cope with the reach and mounting pressure from the local favorite. By the middle rounds, Ayala Lardizabal began digging to the body with increasing frequency, a strategy that ultimately paid dividends at the 02230 Ciudad de México venue.
Chris Roberts OBE, the CEO of the IBA, praised the atmosphere of the evening, noting that Mexico City’s deep-rooted boxing culture provided the perfect backdrop for the professional series. The show arrived at a time when the sport is seeing a surge in global interest, much like how women’s boxing is entering a new golden era across various weight classes. The IBA PRO 18 event utilized legendary announcer Jimmy Lennon Jr. to introduce the fighters, adding a sense of prestige to the evening’s proceedings.
Ángel Ayala Lardizabal breaks down Jayson Mama with body work
The fight began at a frantic pace at 5:00 PM local time. Ayala Lardizabal used his height and reach to establish a stiff jab, keeping Mama at the end of his punches. The Filipino challenger, however, refused to be a stationary target, landing several sharp counters in the second and third frames. Despite these successes, Mama could not discourage the Mexican, who continued to march forward behind a tight high guard.
In the fourth round, the momentum shifted decisively toward “Cameleon.” He began focusing on the midsection, slowing Mama’s lateral movement. The end came suddenly in the fifth. Ayala Lardizabal feinted upstairs before driving a left hook into the lower right side of Mama’s ribcage. The “liver shot” had an immediate effect; Mama collapsed to the canvas in visible agony, failing to beat the referee’s count.
The performance solidified Ayala Lardizabal’s standing as a legitimate threat in the flyweight and bantamweight divisions. For Mama, it was a bitter disappointment after traveling across the globe to compete in Mexico. The disparity in regional styles was evident, as the Mexican pressure-fighting school once again proved difficult to overcome on home soil.
Jonathan Fierro dominates Sergio Chirino Sánchez in co-main event
The evening was not just about the main event. In the super featherweight co-feature, 22-year-old Jonathan Fierro continued his ascent by defeating Sergio Chirino Sánchez. Fierro, who improved his record to 22-1 with 18 KOs, utilized relentless aggression and heavy combinations to control the tempo from the opening bell. Sánchez, now 23-3, found himself pinned against the ropes for long stretches of the contest.
Fierro’s victory further establishes him as a top prospect to watch in 2026. As veteran champions evaluate their futures—much as Terence Crawford thinks Canelo Alvarez might not quit anytime soon—younger fighters like Fierro are positioned to take over the mantle. His power was the story of the night, as he forced Sánchez into a defensive shell for most of the ten-round distance.
Undercard results from Arena CDMX
The undercard featured several quick finishes that kept the Mexican fans engaged. Julian Mendez stopped Joseph Martinez in the third round of their super welterweight clash, while Miguel Angel Martinez dispatched Argentina’s Nicolas Blanco, also in the third round. These shorter bouts highlighted the IBA’s intent to feature local talent alongside international contenders.
Nigerian brawler Ridwan Oyekola, known as “The Scorpion,” provided one of the night’s highlights by stopping Manuel Alex Romero. In a more tactical affair, Tomas Mendoza Valenzuela managed to outpoint Cristian Alberto Eusse of Colombia. The diversity of the card reflected the IBA’s goal of creating a global professional circuit.

His team is expected to look for a world title opportunity or a high-ranking eliminator in the latter half of 2026.
The IBA PRO series continues to expand, with Chris Roberts OBE confirming that bringing elite athletes to iconic venues like Arena CDMX is a cornerstone of their strategy. While some major fights remain caught in limbo, such as the contract talks delaying the Fury and Joshua match, the IBA appears focused on maintaining a consistent schedule of professional dates to keep their roster active.
