On Friday, the unexpected happened: Andrew Knizner was nontendered and the Cardinals officially ushered in the Ivan Herrera era, which is just very fun to say. I should say that’s what it looks like from the outside looking in. Theoretically, they could still trade Herrera and pick up a backup from free agency. That seems unlikely given that they probably keep Knizner in that situation.
But to use one example, what if for some reason the White Sox are really enamored with Herrera and Herrera is most of the way to a trade for Dylan Cease? The Cardinals probably make that trade.
