Steve Erceg has never looked forward to a fight as much as Brandon Moreno . Erceg (12-3 MMA, 3-2 UFC) takes on former two-time flyweight champion Moreno (22-8-2 MMA, 10-5-2 UFC) March 29 in the UFC on ESPN 64 main event at Arena CDMX in Mexico City. Moreno is a fight Erceg has always wanted . So much that he finds himself more excited to take on “The Assassin Baby” than he was when he challenged flyweight champion Alexandre Pantoja at UFC 301 .
