I'm definitely one of those people who is terrified at the prospect of his arm falling off. This course of action seems smart to me, both for the team and the player. Graterol is already an impact arm in the bullpen. He can get major-league innings, while working up his stamina by throwing multi-inning relief appearances. Every year, you reevaluate and see if he's ready to start. But if not, it's no sweat, he's already very useful to the team, and there's no shame in a career as an elite reliever.
