Very nice play by Bernier. Here's the logic, as I see it. You need to sign some AAA filler every once in a while, and guys like that are handy. They will be more likely to sign if they can get a chance in the majors. The Twins need more middle infielders, and maybe it won't be Bernier, but it doesn't hurt to let him have a couple of weeks and see what they've got. If he doesn't work out, fine, they DFA him because they're going to need to clear a bunch of spots on the 40-man next year anyway. If he's better than expected, then they have a tough decision that is good news. What's the harm?
