Mario Barrios 142 lbs beat Richard Zamora 141 lbs by KO at 2:16 in round 4 of 10

  • Questionable stoppage. Barrios engaged in a brief four round slugfest with exciting substitute Zamora, who was shorter than Barrios and could not overcome the size differential. However Zamora was punching back into Barrios' attack and appeared game when the referee stopped it.
