SAN JOSE, Calif. – “Big Tuna” was a massive underdog going into Bellator 266, but he defied the odds in a matter of seconds.

Some online sportsbooks had Ben Parrish as high as a 6-to-1 underdog against rising star Christian Edwards. So when Parrish (5-1 MMA, 1-0 BMMA) knocked out Edwards (5-1 MMA, 5-1 BMMA) with a series of punches 38 seconds into Round 1, the SAP Center was sent into a frenzy.

A hard overhand left started off the finishing sequence. As Edwards crumpled to the canvas, Parrish poured on a series of punches that put the lights out.
