And if ever that happens, he should move up in the next division which is the bantamweight division which has more difficult boxers.
As long as Inoue already become undisputed champion and there's a new vacant belts for every new boxers, bantamweight division wouldn't become hell division anymore and Ancajas can compete with the other boxers just like his legend e.g. Donaire and Casimero. But it's too early for Ancajas to move to the next weight division since he should at least get a belt in his current weight division first.
If he's failed to beat Martinez, there's other champion that he can take a challenge.
