I'd be asking (as the Twins staff)...under what circumstances will we EVER let him play CF again. And as soon as that criteria is met, I'd play him in CF.
Maybe, they're doing this. Or, maybe they've simply put a time-frame on it (a different one than what we heard at the beginning of the year)?...to 'prove' that the leg is holding up first.
But maybe they're headed toward logic that dictates that it will ALWAYS be the low-risk (and therefore 'correct') choice to DH him. Here's were it's a slippery slope, IMO. Prolonging the career of an 'ok' DH doesn't do that much for the team in terms of wins and losses. Especially, with 'good' DH alternatives proliferating as I type (Julien, as you pointed out, Wallner to name a couple)...and no viable CF alternatives (beyond MAT) on the horizon. (Also why I don't get anchoring Lewis at 3B.)
FWIW, they're losing me with backing down from the statement at the beginning of the year when they said Buxton would be playing the field sometime around the middle of the year. What's changed? Maybe it's MAT hitting better than expected?
Probably 80% of the frustration with me is that I simply don't know what they're doing...what their longer-term plan is with Lewis and Buxton position-wise. I can't see the logic/pattern with what they're doing, and usually you can see one. Doesn't mean that whatever it is they plan isn't reasonable or 'good'.
