He might be a natural! Or he could just plain not be good at it. Someone internal has to grab that position and be good at it. I have never understood why a team would platoon 1B. For Baldelli to trot out 3-5 different guys a month has to have a negative effect on defensive efficiency! It would make sense that over the offseason, Castro has been approached with the idea before it was made public. Maybe he has been taking reps for months to focus development on 1B to see if its even viable. Same could be said for Julien. Julien doesn’t seem as viable because he just isn’t that athletic. He just looks slow/mechanical. Not fluid or natural and that has disaster red flag 🚩 flying, screaming don’t go there, written in caps.
If Castro hasn’t been putting some work in this offseason, that could be just as disastrous.
Miranda, if healthy and focusing on full time 1B, he could actually be serviceable. His bat plays there (when not in a slump) Maybe he can mature as a player and focus being serviceable at D and hit the cover off the ball.
