Celestino Caballero vs Jason Litzau

Caballero couldn't find any takers at featherweight even though he'd pursued Juan Manuel Lopez since both were super bantamweight titlists, so instead he took what was supposed to be an easy fight at 130 lbs. against Litzau. It turned into anything but, as Litzau made his size difference, workrate, and commitment to the fight tell in a close decision victory over Caballero, who looked listless and undertrained for most of the bout.
