For the rest of my baseball life, I will probably insist that Garrett Whitlock could’ve made it in the rotation— and likely would’ve been more valuable there — which is what I’ve been saying about Jonathan Papelbon all these years. But regardless of hypotheticals, there’s no question that he’s really damn valuable right where he is right now. And he doesn’t seem to miss starting, either, saying that he loves being the Red Sox’ “Swiss army knife.” (Peter Abraham, Boston Globe)
By fWAR, Whitlock has been the most valuable member of the bullpen and third-most valuable pitcher overall.
