I think signing Santana was a great move. Trevor May needs to learn how to throw strikes consistently, he'll always be a liability until that happens. He did it for a long stretch in Rochester, but lost it after he missed some time with a minor injury. Until he gets to a point where the control is never an issue for him, you can't hold a rotation spot open and pass on a proven commodity like Santana. Make May or Meyer beat the other one out, there's nothing wrong with a little competition. If Berrios is lighting the world on fire, you can figure out a way to make room for him assuming everyone is healthy.
