Just think back to how Buck Showalter brought in Ubaldo Jiminez in the 11th inning of the wildcard game instead of THE BEST RELIEF PITCHER IN BASEBALL.
Did he lose the game? No, the players did. But he did put his team in a SIGNIFICANTLY worse situation vs going with Britton.
We have witnessed Charlie put the team in a significantly worse situation vs the average manager probably 4-5 times IN ONE WEEK. Imagine how much these mistakes will be magnified if this team makes the playoffs again. Imagine being on the Orioles side of that wildcard game, because that definitely could be us this year.
He HAS to go.
