Martínez Declares Himself a Dark Horse in the 168-Pound Division With Latest KO
On ProBoxTV, Lester Martínez—Guatemala’s rising KO machine in the super middleweight (168 lb) division—made a bold claim: he’s the true dark horse in boxing’s most competitive weight class. And with good reason.
On Saturday, March 22, 2025, at the Orange Show Events Center in San Bernardino, California, Lester Martínezdelivered a commanding performance, defeating Joeshon James via a fourth-round technical knockout. This bout, which had been postponed twice previously, was broadcast live on Fubo Sports and Probox TV.
Martínez, hailing from Guatemala, showcased his power and precision throughout the match. In the third round, he landed a decisive combination—a right hand followed by a left hook—that sent James to the canvas. Although James managed to rise before the count, he appeared unsteady. In the fourth round, Martínez continued his aggressive approach, delivering another powerful right hand that floored James once more. Recognizing James’s compromised state, the referee halted the fight at 1:05 of the fourth round, awarding Martínez the victory.
With this win, Martínez improved his professional record to 19-0, including 16 knockouts, and successfully defended his WBA Continental Americas Super Middleweight Title. His performance solidified his status as a rising contender in the super middleweight division .
Guatemala & BoMac
Martínez, trained by Brian “BoMac” McIntyre (the same mastermind behind pound-for-pound king Terence Crawford), has been sharpening his skills in Omaha, Nebraska, far from the limelight—but not far from greatness.
With a growing highlight reel of knockouts and a perfect professional record, Martínez is starting to look less like a prospect and more like a future title threat. His explosive power and disciplined camp have boxing insiders paying attention.
If his momentum continues, Lester Martínez could become the greatest modern boxing figure ever to emerge from Guatemala—a national flag-bearer with global ambitions.
