Vic Darchinyan has traded blows with a renowned warrior several divisions above him, as he prepares to fight the much taller Anselmo Moreno in a bantamweight boxing unification world title bout.

IBO champion Darchinyan left Australia on Saturday, November 12, bound for Los Angeles where he will continue his preparations for the December 3 clash with Panama's WBA Super title holder.

Fellow southpaw Moreno will enjoy a considerable height advantage of around seven centimeters. He has spent much of his career at bantamweight while Darchinyan has moved through the divisions from flyweight.

Darchinyan has been sparring with Filipino lightweight and southpaw Czar Amonsot, who is almost as tall as Moreno and is best known for his epic 12 round contest with Australian Michael Katsidis.

"He's given me good sparring, I'm happy with my speed and my power," Darchinyan told AAP. "Czar is heavier than me by five weight divisions and I know my power is good enough for my opponent."

He reiterated he intended moving up to super bantamweight unless he got more opportunities to unify the bantamweight division if he beats Moreno, Wide World of Sports reported.
