It's such a weird situation, since we don't want Ballesteros languishing in AAA when he could be a useful hitter in the majors, but he needs regular repetitions at catcher to continue his development, and it's clear that he is not ready to be a catcher in the majors. This also isn't a Schwarber situation where you can talk yourself into thinking he could play other positions because he lacks the sort of body type you would want elsewhere on the field.
I love the potential, but he's an awkward fit going into 2025 for the Cubs, It'd be one thing if he played for a team that was tanking and didn't give a crap about his growing pains at catcher in the majors, but for a team in contention? Engh.
