Not Trading Mata for Frazier. Just turned 18, moved already to Single A. Nope. I know early but he is at Single A, and doing alright. These are the Trades that kill your Minor Leagues, not a kid like Ball, whose ceiling is questionable.
In fact that would be my rule if I were a GM, Trade Rentals, for Questionables.
Meaning with a different system, Coaching, they might be a Diamond in the Rough for another Organization. That would be my selling point.
With Mata you just don't know how good he can be. These White Sox Scouts are slick.
