Both will sure make adjustments on the fight. And even a weight drain Ancajas can absorb Martinez best punch, what's more if Jerwin is in his best shape and no issues with weight? It could be a different outcome. And so this is what we are expecting from him in this fight. Bring the fight to Martinez and be a banger, the style that he is known for.
Let's see if he can prove to the world that he is the better fighter, it's hard to just speculate, we should give respect to the winner, yes, Ancajas may have struggle maintaining the weight but there's nothing to be blame of, but himself and it's not a valid excuse.
Yes, if he losses again then we can say that Martinez is the better fighter and has every right to end Ancajas reign as of the longest super-flyweight. But if he win by a dominating fashion, then he is back and the first win by Martinez could be considered as a fluke. And the best thing for Jerwin is maybe go up, nothing for him to proved because he has been a champion in this division for many years already.
He is actually the better fighter already because he is the champion, Ancajas is just trying again hoping he can beat a stronger Martinez, and though I'm optimistic that Ancajas will win, but I believe it's going to be very difficult for him beating Martinez. Well, it's time for him to prove that his excuse is valid, and that is by winning here.
He still has a chance to win though if we are going to factor that he is weight drain in their first fight and if he just healthy, he could have secure a unanimous decision.
Now, barring all excuses, and assuming that Jerwin will come in healthy 100%, no problem with the weight whatsoever, then maybe he will going to beat Martinez as expected by the majority here.
