If the Berrios non-move wasn't about service time, I can think of one reason Ryan wouldn't have promoted him- respect for the manager's domain. There's no evidence I can think of that TR has ever told his managers how to use the 25 he gives them. Not who to start, where to play them on the field, how many innings to give them, how much rest to give them, etc. Once he turns over a player, he is hands-off. And I suspect he fears how Molitor might use Berrios in a WC race and in the playoffs. Eg. back to back days out of the pen or worse, slotting him into the rotation which would push his innings well into the 200s in the worst case scenario that the Twins advance deep into the playoffs. Maybe that sounds conspiratorial but it seems consistent with the Twins' MO and its an approach I respect but maybe this is one case where it bit them.
