Seemed early to me, guy dominated most of the fight and got stopped after just one knockdown that was mostly fatigue not concussion. He was still trying to hold on and defend himself, exactly what you should do in that situation. If it had carried on mostly likely would have been stopped but you have to give a guy a chance. Shame to see after McClosky fight, Prescott is a good fighter who could have done alot more with a top trainer.
Legit stoppage imo, Prescott was really hurt by those uppercuts and looked completely out on his feet.
Alvarado was up and the last round knockdown wouldn't have won it for him (which I think it should've) The stoppage was legit anyway imo Prescott looked gone and to my knowledge (locked straight onto ESB) there wasn't any complaints and that is usually tells alot.
