There may be a 7-10 guys with more value for the roster than Butera in Rochester. I don't care that it may only be 2/3 of a win. It's still 2/3 of a win, A, and B, some of these guys could overperform (Carson, Hollimon, Bates, etc.), but we know Butera is going to bat .200 at most and maybe crack .550 OPS if extremely lucky. It seems that the Twins have plenty of guys who could top .650 OPS. Is it so much to ask for a bench that has adequate or better than adequate bats at least in some situations (LH/RH)? There is no situation where one would ever want Drew Butera to be at the plate than any of those players. Even though he has sucked at Rochester (who cares given he is splitting time with two duds), if Gardenhire is so hellbent on having three catchers, I would prefer to see what Towles can do when given the opportunity.
I always laugh when I hear something like "at least they know what to expect from" x player (often Nick Punto was that x) as a reason to sign or utilize that player. Well we know exactly what to expect from Butera (and Rivera) and that is badness.
