To DL, or not to DL, that is not the question. To me it's a red herring. Instead it's a nagging injury that the Twins' medical staff did not find an answer to. It "lingered", in Terry Ryan's word (makes me worry the implication is "malingered", too), for a while, finally they decided in some fashion for him to just play on it, and a day later it became enough of an issue to DL him for it. Doctors and trainers aren't miracle workers, and I'm sure every team goes through diagnoses and prognoses like this one. Still, now that we are sensitized to it, it rankles to go through the maybe-he-can, maybe-he-can't, status for Darin for several weeks. If it's some kind of stress fracture that wasn't caught until repeated stress made it acute, that's bad. I don't know how to judge a medical staff, you just have to collect anecdotal evidence until a bigger picture emerges. That, to me, is what the hoohah is about.
