Who in the world at 125 lbs. can defeat Alexandre Pantoja? At UFC 310, Pantoja defended his UFC flyweight strap for an amazing third time, stopping the highly-touted Kai Asakura in the second round by rear-naked choke, becoming the only man to submit the Japanese phenom. Prior to their encounter this past Saturday night, Asakura had arrived into the promotion with much fanfare behind him, being a former two-time Rizin Bantamweight Champion. Despite the size difference that the challenger possessed, Pantoja looked to be in a whole different league than Asakura.
