I won't go into specifics, since people will easily figure out who it is. He's won more than that, including national championships.
Saw this gif the other day and it made me think "That's karate in MMA" (I know what he's doing is technically illegal in MMA). Basically dirty clinch fighting. Control the limbs and bash his face and head with the other. That to me is basically the essence of bunkai based, old style karate (before it got filtered through the Japanese University system and ippon humite). Grab, control, bash...Bosch.
No! It was a failure of the other guy to bring teh awesome wrist-grabbing counters! If only he'd done Aikido!
