May is a major leaguer. If he needs time come spring, I'd have him as an EST candidate and send over to Rochester when he's ready to start pitching. That might not be the right answer, but to me he deserves a spot on the ML team as soon as he's ready. He would be my top choice for 5th starter if he's ready out of ST. I do think that the 5th spot should be a rotating spot given the depth of talent that will exist in the high minors. Just about (if not) all of those guys will be on the 40 man, meaning that they do not need to have too much patience if a guy cannot make it out of the 3rd inning for multiple starts. If Santana is traded, I think they go with a 1 year deal for someone on top of a big FA signing. Just my two cents. I agree that I don't think it would be wise to go into 2018 without making an FA splash, and that is if they keep Erv. As for Hurlbut, I've never been too high on him, but I do agree that he's been good enough that he should be in this conversation too.
