While I understand the logic of moving him to the pen to increase the likelihood of getting meaningful innings out of him, I also wonder how often the Twins will have access to a pitcher with his skillset and potential to be a frontline starter. Obviously, they're not going to sign too many of those guys as free agents and they seem to prefer taking shortstops high in the draft versus arms. My head says move him to the pen, but my heart says roll the dice and keep him as a starter.
I also wonder how much harder is it on an arm to go 85 - 90% for 5 innings once a week versus 100% for an inning 3 times a week coming out of the pen? Not sure if there are any studies that may give insight on that.
