Well first of all, he's not hitting a reasonable number of doubles and triples so far, he's hitting epically few doubles and triples and I include that in power. He spent this season pounding the ball into the ground, his groundball to flyball rate was genuinely bad and that's the biggest reason why he had so few doubles and triples, he had a worse groundball ratio than anyone in the big leagues. I cannot rule out that this was the fault of his wrist injury, but that's a legitimate worry, that number of ground balls would make him a genuinely weak hitter once he got to a level where the fielders are decent and where the pitchers will have the stuff to strike him out more.
Secondly, if he's only hitting a "decent number of doubles and triples" while being a really good fielder, then he's not going to be a good enough player for me to want to move Moncada unless I'm giving up on Moncada completely, and that'd be my answer to the question posed in this thread.
Maybe he breaks out next year, maybe it was all the wrist, maybe he will light up AA this year, but right now he looks like a guy with a long way to go, he looks like a guy who if he gets called up we'll be wondering what is wrong with our scouting. If this were my franchise, I wouldn't care a lick about what his draft status was or why that requires me to move him fast, his numbers in A ball this year were such that I would be putting him in A ball to start next season and he would have to prove to me that he's ready to move up before he reaches AA.
