I think aj beats Ruiz in the rematch , in the first fight he just got caught with a very good shot when he thought he had Ruiz hurt and never really recovered for the rest of the fight. It cracks me up how after one loss some people have lost their minds over it, the dude just lost a fight, no one in mma would even blink at one loss, but then the best fighters fight the best fighters all the time in mma.
