I figured catching was up in the air, due to the poor showing the Sox received from the position analytically. The only name mentioned that I’ve seen so far was Francisco Cervelli, which may have happened to some extent, but these types of contact can get reported with more enthusiasm than actually existed.
Cervelli seems like a questionable choice. He’s a very good catcher on a short deal that won’t hamstring anything beyond 2019. But his history with concussions is alarming.
I haven’t read any other catcher names mentioned in conjunction with the Sox. I do strongly believe they cannot afford Realmuto without doing something drastic and potentially stupid (like swapping Benintendi).
As for 2b, it is possible the Sox make a Rule 5 pick for the position, someone like Max Schrock or Kean Wong. That way, if Pedroia is healthy, they simply return the player. No harm, no foul. Given the recent and perfectly timed DFA of Robby Scott, it is a possibility. ( Grabbing a reliever is more likely.)
But catcher could get interesting. The goal is likely an offensive upgrade while minimizing defensive subtractions. Not sure who the target is or what it takes to get him. Wilson Ramos is a nice fit, but he will cost and leaves less budget for the bullpen. Yasmani Grandal, who is better defensively than he showed in the postseason, is the cheaper free agent option. But can they afford him while adding relievers.
