As for Ancajas, he has more than enough reasons why he needed to win this fight because his career will go down if he will get defeated again by Martinez. But I believe that this time he can defeat Martinez and maybe he can go fight with Joshua Franco afterwards to claim the WBA belt.
If Ancajas doesn't get any trouble in gaining the required weight limit, I am somehow confident that he can win this rematch. We will see a different Ancajas since he will be fully conditioned and possibly have enough stamina to box until the 12th round. We have seen the capability of Ancajas to absorb Martinez's punches, so we don't need to worry about that. Besides, I think Martinez will slug it out again and I believe Ancajas will have a counter strategy for that.
Ancajas already taste those solid punches from Martinez and he manage to survive till the last round, if he is able to maintain his weight and continue to have a good training predations the chance of winning is possible, it's just a matter of adjusting with how your opponents fight, he might not be too much exhausted this time as he has a condition of health and his sparrings will help him to adjust with how he will react to each possible attack from Martinez.
Expect a good counter and solid throwing of continuous punches and not just to cover and try to counter, but also to create the attempts of attacking and boxing Martinez.
Martinez is not a mystery anymore for Ancajas as the latter already fought him during their first encounter but unfortunately, unlocking that mystery is an expensive move because it cost Ancajas his belt. There have been some reasons why Ancajas failed to defend that belt but they should move on and the camp should make some way to keep the Filipino boxer fit and healthy as I know that this time he will defeat Martinez.
Yup! no time to dwell with that past mistakes but more into moving forward in finding the betterment of Ancajas fighting plan on his upcoming rematch against Martinez, more on how they will bring good sparring to practice and perfect the plan that they wanted to execute, you said it right Martinez is no longer a mystery and that last lost will give Ancajas additional inspiration to do better, though it was the belt/title that cause that one for him but he have his chance now to bounce back and re-try to win it back.
Ancajas already has a new nutritionist, let us wait and see how does this new nutritionist enable Ancajas to solve his weight problem and at the same time nourish him back after the weigh-in.
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 believe as well,, he did manage to survive though he lost it but absorbing those solid punches he can take it and if he can counter and throw solid punches, I see that he will have a better chance.
