If Inoue becomes a unified and then undisputed champion, he might move up again.
But I highly doubt Casimero's performance against Fillipus Nghitumbwa would suffice to defeat Inoue. He better increase his stamina first because he cannot just throw those haymakers and expect it to land as always, plus it's more exhausting if it misses. Casimero definitely has the power punch but fewer jabs will make him lose if ever the fight will turn out in the judges' decision.
I want to see it happen though and just end that long trend about why Inoue is avoiding him.
Although when I check the rankings now, and if I'm not mistaken, Casimero is rank 8 before his fight and with this win, he bolted to rank 5. So most likely, if I wanted who Casimero should fight next, it could be Luis Nery or Ra'eese Aleem in WBO.
Him and Nery has been calling each other out since Casimero become a champion at 118 lbs and Nery that time was a champion too at 122 lbs. And now that Casimero has move up in weight, it make sense that they can now fight.
It will be nice to see him fight a former champ from this division as it can boost him up if he will manage to win over Nery, the timing is important as there are many fights that may take place before they will negotiate his next fight, we all know that this sport is not just an ordinary one but a business that needs to have a good promoter so everything will be in place.
Skills wise, Casimero needs to keep adding more in enhancing his potentials it's not that far from his last weight and his body already adopts this new one, so better to make complete adjustments both on his speed and his power combinations.
