Reito Tsutsumi def. Ray Rojas by TKO in Round 2

Immediate Reaction: Destructive performance by Tsutsumi, who didn't waste a second or have a second thought about going straight after Rojas from the opening bell. With it being clear Rojas couldn't get Tsutsumi's respect, the fight was essentially over. Tsustumi stalked, landed heavy power shots, and dropped Rojas twice in the second before having to be saved by the referee. A step up for Tsutsumi seems appropriate given the dominating effort.

Round 2: Hard left hands land for Tsutsumi, then a third just moments later. Rojas really under pressure and NOW A FORTH LEFT DROPS ROJAS! Tsutsumi wants to end this right now if he can manage it. Rojas along the ropes and trying his best to counter but he's taking punches back and he literally melts into a heap in the corner for a second knockdown! Rojas gets up and continues to try his best to fight back but he's eating power shots to the head at will. The referee sees enough and stops it. Tsutsumo TKO-2 (2:27)!

Round 1: Tsutsumi comes out on the attack immediately, applying tremendous pressure as he looks to inflict serious damage on Rojas early. Rojas tries to fight Tsutsumi off but gets caught with a bigger shot during an exchange. Strong jab lands for Tsutsumi. It's clear early that if Rojas can't get Tsutsumi to respect his power, well, it's going to be a long (or very short) contest. Rojas goes down on what's ruled a slip during an exchange. Tsutsumi comes right on the attack and lands some heavy shots as he tries to press the advantage. Tsutsumi 10-9.
