The 29-year-old Muratalla quickly took control of the fight, forcing Cruz, who looked physically weaker, to defend. The Cuban relied on speed and counterattacks, but Muratalla was steady and often landed his right hand on target. The American thus had a successful first defense of the championship belt, which he won last year.
At the same event, Israil Madrimov returned to the ring after losing to Vergil Ortiz, defeating Luis Salazar.
