The Reds decided to go with four dedicated outfielders, sending Fairchild down.. That provides a need to have one or two players who can fill in in the outfield. If Pinder makes the club, he can play in the corners occasionally. Barrero can play in CF occasionally.
That’s all I see in this.
Barrero is primarily a shortstop and initially they will determine if he can be a regular there. If so, they have a valuable asset to play or trade.
if not, then they can consider a position switch or a utility role. In that case, CF would be in his future.
