Joan Guzman dominating Jason Davis to a second round TKO via corner stoppage. Two illegal blows in the first RD. When the second round started, Guzman immediately went on the attack, backing Davis into the corner. From there the Brooklyn fighter unloaded a series of right and left hands at will. Before the referee could intervene, Davis’ corner sent not one, but two towels flying into the ring to halt the carnage. The official time of the stoppage was :29.
