He may have not scored a ko but he thoroughly dominated him to the point where Roach had to end it. Got to love Penalosa though. He would have stood up to Vasquez' or Marquez' assault had he faced either on that night.
you guys and your poor boxing knowledge shouldn't be allowed to post on ESB...Penalosa has one of the best chins in boxing...but juanma did ko Deleon
You also have to consider that Juanma is a way bigger and younger and stronger than Penalosa. Penalosa has been fighting since Juanma was sucking on his mom's tits. Juanma is good but not that good. This is ESB not an Elite Boxing forum where you have to have a Degree from Harvard. This is all just based on opinions.
