The St. Louis Cardinals may have just filled their rotation by resigning Adam Wainwright and committing to bring Carlos Martinez back to the rotation, but they should still be going after pitching. If last Spring Training didn’t explain why enough, just know that starting pitching situations can change in the blink of an eye.
A rotation of Jack Flaherty, Miles Mikolas, Carlos Martinez, Dakota Hudson, and Adam Wainwright isn’t bad, but having another name in there for depth and to give some competition is not a problem.
