Renato Moicano’s climb up the featherweight ranks continued tonight at UFC 227, as he took out longtime contender, Cub Swanson, in the opening round.

Swanson came out firing calf kicks and some big punches, while Moicano returned fire with kicks of his own, and a stiff jab. Later in the opening round, Moicano sent Swanson to the deck with a stinging jab. In the ensuing ground battle, Moicano locked in a fight ending, rear-naked-choke.
