My only worry would be that last season they started him on a throwing program and had to shut him down with elbow pain after 6 weeks. To me that is a problem. I don't believe Rodon had any similar issue like that, he was just put into some tough spots by Ricky immediately which made him look really bad.
thor could absolutely be healthy and ready to go, but from the outside I am just saying that it could be pretty risky for a team that really needs pitching
