The Pirates went into the season deciding that they wanted to get the majority of their minor leaguers playing time at positions other than their natural one.
In theory this works out perfectly, there are only so many starting spots available at the major league level, and the best way to ensure you get on the field as much as possible would be the ability to play multiple positions.
That plan, however, traditionally goes to the players that are going to be competing for a spot on the team’s bench. Not exactly the ideal scenario for a player ranked as a Top-100 prospect in all of baseball.
