Volume and relentless pressure once again proved to be the winning formula for Jarrell “Big Baby” Miller. In a physically punishing heavyweight clash, the Brooklyn native earned a unanimous decision over Cuba’s Lenier “El Justiciero” Peró on Saturday, April 25, at the BleauLive Theater inside Fontainebleau Las Vegas, securing his position as a top contender in the World Boxing Association’s heavyweight division.

The fight opened with Peró in control, as the Cuban southpaw relied on his Olympic pedigree and technical polish to keep Miller at bay through the first three rounds. Using fluid footwork and sharp hooks, Peró appeared to have the rhythm figured out, frustrating Miller’s early attempts to close the distance. However, beginning in the fourth round, Miller’s sheer mass and constant forward pressure—having tipped the scales at 305 pounds—began to shift the momentum.

The turning point came in the second half of the bout. True to his bully style, Miller forced Peró into close quarters, punishing the body and landing heavy uppercuts that gradually wore down the Cuban’s conditioning. By the eighth round, fatigue had clearly set in for Peró, who struggled to keep pace with Miller’s relentless work rate—an unusually high punch volume for the heavyweight division—as he was backed up against the ropes.

After twelve grueling rounds of physical warfare, the judges returned scores of 117-111, 117-111, and 115-113, all in favor of Miller. With the victory, “Big Baby” (28-1-2, 22 KOs) not only hands Peró his first professional defeat, but also positions himself firmly on the brink of a world title opportunity.

Following the fight, Miller wasted no time calling out Deontay Wilder, targeting what he described as a definitive all-American heavyweight showdown for late 2026. Meanwhile, Peró (13-1) suffers his first setback as a pro, showing flashes of elite technique, but ultimately undone by the decisive factors of size, pressure, and punch volume on a demanding night in Las Vegas.
