The Louisville roster is full of players who will very soon need major league playing time.
Alonso, Francisco, Dorn, Valaika, Cozart.
(I assume Frazier could use another year at AAA after his slow start this season.)
On the pitching side there are Chapman, Maloney, Lecure, Jukish, Del Rosario, Burton, Herrera.
And maybe Fisher and Smith go to AAA when Izzy and Springer come up. That only adds to the logjam.
The Reds obviously don't have room for all of them. They can't keep them at AAA as insurance forever.
Isn't there a logjam that requires some promotions and some deals? Reds can't just sit with all these guys at AAA indefinitely.
