Two factors why Ancajas lost from the fight, lack of training because of the sudden replacement and second is he is not in good state where he can give a good fight to Martinez.
We should stop saying the sudden replacement of the opponent is one of the reasons why Jerwin Ancajas lost. That was a
sh*t reason for a champion like him. On the other hand, Martinez is also on the same as he suddenly becomes a challenger and will face the champion.
Both of them have the same time to do the preparations.
It's clear and is also mentioned by his camp that Ancajas is not really in his shape on that fight because of overtraining to reach the required weight. That's it.
Yes, it's not that Martinez is a replacement fighter, it really boils down to
a) his weight issues
b) overtraining
So both really contributed on his performance and they admit to it afterwards. Yeah, they might be thrown off a bit by Martinez as a late replacement but he could have perform better and win the fight if those issues didn't arises in his camp.
Overtraining? I don't think it's a big issue though, I guess the real problem is the weight issue because boxers know if they are undertrained or overtrained. Anyway, it's already over, this rematch, we will see how Ancajas will make the right adjustments.
