Another guy who may be available at the deadline is Greinke. I say “may” because currently the Dbacks have a better record than the Cards so I don’t know if they are still in rebuild mode.
Pros to Greinke:
1. Still an elite pitcher.
2. Controlled through 2021. Not a rental.
3. Borderline hall of famer
Cons to Greinke:
1. Still owed a massive amount of money. Dbacks would have to pay some of it down.
2. Flaky personality. I think he once even had some derogatory things to say about the Cardinals.
3. He is 35.
