Moncada couldn't feidl and he was promoted to AA then MLB in the blink of an eye.
He has started 171 games at 3B in the minors.
If he's that bad, keep him at Salem, and let him learn 1B. I know he's 5-10 or 5-11, but if he can't play 3B, then what?
Also, can't a player learn defense at AA? I thought thatw aqs why Devers isn't in AAA.
