Ancajas indeed see how Martinez work, I believe Ancajas can absorb Martinez's strong punches without any problem, we have seen it in their first match. Now all Ancajas need to do is not to get in a brawl and use his jobs and straight frequently. I don't know if Ancajas has the power to knock out Martinez but Ancajas must outpunch Martinez and dictate the tempo of the fight. Ancajas is taller and probably has a longer reach, so he should use that to his advantage.
I agree though that if only Ancajas is not overtrained during that fight and he is in good condition, he can absorb all the punches that Martinez will throw no matter how strong it is. Just look at him being able to finish the whole 12 rounds even struggling and not in his usual condition.
However, we can't hide the fact that Martinez is also good. He surely knows that Ancajas is now working on maintaining his good shape that's why I'm expecting him to also do some adjustments like what Ancajas is preparing right now.
