On Saturday, March 21, 2026, Lester Martínez, the pride of Petén, made history by becoming the first Guatemalan boxer to capture a world title, defeating Immanuwel Aleem by unanimous decision at the National Orange Show Event Center in California.

With this victory, Martínez claims the WBC Interim Super Middleweight World Championship, consolidating a career that today positions him as one of the best fighters on the planet at 168 pounds.

The conquest of the world title is the result of constant evolution. Martínez, who burst into the professional ranks with a stunning knockout over former champion Ricardo Mayorga, has demonstrated technical maturity and elite power in every performance.

2025 was the year of his definitive consecration among the elite. In September of that year, Martínez starred in what specialists and fans categorized as one of the best fights of 2025: a clash of titans against the undefeated Frenchman Christian Mbilli.

In a titanic power-against-power battle in Las Vegas, both warriors ended in a close draw that left the boxing world demanding a rematch and confirmed that the Guatemalan had the level to rub shoulders with the biggest names in the division.

With an undefeated record of 20 victories (16 by way of knockout) and 1 draw, Lester Martínez is no longer a prospect; he is the monarch who has placed the blue and white flag on the global boxing map.
