It's not that far from the last weight division where Casimero became a champ, he can still move the same and his fighting skills especially his speed is still applicable though the opponents strength might be tougher from this new weight but proper adjustments and enough trainings and sparring may let Casimero to stand out and bring the win.
Casimero always put a lot of efforts on the training when it comes there's a new opponent. Wherein he always push his limit. so for me it's not surprising that despite of the record of the opponent he can win and knock it out.. This will be more interesting to watch tbh.
Let's find out. I believe he can win against Akaho. Akaho is already 36 and fought for a world title 2 times but he failed them all. This is only a tune-up fight for Casimero at 122 to shake off his ring rust and test his new weight but far to become a basis for his chance at WBA/IBF champion Murodjon Akhmadaliev and WBO/WBC Stephen Fulton.
If Casimero insists on staying at 122 after this, he will have to fight a top-10-ranked opponent in order to solidify his position late next year. Akhmadaliev is expected to fight another Filipino in Marlon Tapales early next year for his IBF mandatory defense. I think Fulton is the target of Inoue next year if he beats Butler and becomes undisputed.
Another interesting stuff I learned is that Akhmadaliev is now promoted by Matchroom Boxing a partner of DAZN. Fulton is promoted by PBC and uses Showtime and Fox as its channels. Inoue is with Top Rank whose fights are televised by ESPN. I begin to wonder if Inoue can really fight Fulton after his Butler fight. Casimero after a fallout with Manny Pacquiao's promotion signed with Probellum a close friend of PBC although I am not sure if the contract remained valid after the cancellation of his previous fights.
