The “Mongolian Assassin” got off to a strong start, crushing Perrin with long, clean strikes in the first that put the Lowell, Mass., native in a chair a few different times, showing off the power he carries now that he’s fighting in the bantambars. As the fight wore on, Aoriqilingen’s tank began to dwindle and Perrin began to have more success, controlling most of the final turn in the clinch before the duo let it rip in the final 30 seconds.
