The top catcher in this draft class without question is Patrick Bailey out of North Carolina State. Bailey is already very able behind the plate with a strong arm and relatively smooth actions which gives scouts a lot of confidence that he will stick at catcher. He also has some interesting upside with the bat as he is a switch-hitter with some pop from the left side of the plate. The team that drafts him will be getting a polished receiver who has all of the tools to be a very able catcher for a long time.
The question with Bailey is whether or not he can be a standout offensive catcher and that seems to be less likely. Being a switch hitter is a definite plus, but he isn’t amazing from the right side with some even wondering if he can be serviceable long-term as a right-handed hitter. The track record of performance is there, though, and the offensive bar for catchers just isn’t very high. Even if Bailey never ends up being a star at the plate, his value will come from the position he plays rather than where he would bat in a lineup.
