Either or both of Moncada or the experts that judged him ready for MLB.
Now if he was brought up as a "reward" for having a good season in MiLB and so he could get a taste of the bigs that is fine.
However, anyone who has played the game and has watched the game for many years can see that he is clearly not fit for MLB duty yet.
If you or others have witnessed otherwise ( as in watching many of his MiLB games in person ) or have seen him make really smart and proper plays in the field and at bat in MLB I would like to hear about those things in detail.
Everyone is all gaga and blowing loads all over themselves with the "#1 Prospect by BB America" hype train. He must be the next great Red Sox!!!!!!!!
I heard all the same or similar s*** about several guys that ended up fizzling or having only decent MLB careers before.
Until Moncada learns more about the game, refines his techniques, and learns to hit WELL, he is just another really good athlete.
And athleticism and Talent are not synonymous.
