I have watched AAA player come up to MLB and look like they should still be in Legion Ball. The Twins are not AAA they are the Big Leagues. Unless he is proven to be better than Lee, leave him where he is till he gets SO good down there that they feel it is worth taking the chance.
I have not seen AAA players with truly good defense numbers come up and suddenly their glove does not work; although, Lee looked good before he got up , and was very good at 3rd for one season. For some reason, he is losing it, to a degree.
Julien's glove Never looked good in the Minors and he proved it in the majors, I see no reason to think Culpepper is the exception.
I do not, and never will, see any season as a losing proposition - so - it is OK to become a quasi AAA team. Bringing up AAA players early , is doing just that.
There is nothing in St. Paul right now that is any better than what they have -- you can say what about Outman, , they need his glove and his bat, well, when they let his twin brother Fitz go, it was a psychological shock!
