Somebody needs to be the 25th man (and Bernier actually is a player, and will play, so your 24 man argument is phoey, or it's one you should have been making before Vargas was sent down). If Molitor is going to send Rosario, Escobar, Nunez or whoever ahead of Vargas to pinch hit, it's not horrible to have the 25th who can offer defensive flexibility, especially when it's probably just for short duration until Arcia comes back. The plan was probably to send Vargas down, not to keep Bernier up. Things have clearly changed since Spring Training, and the plan should be to do what's best for both Vargas and the Twins long term. Not to maximize Vargas value as semi-player until other players get healthy. The sooner he goes down the sooner he can correct what caused him to go down. I just think that Vargas' longterm development outweighs whatever minimal production he could give the Twins in the interim. Bernier is an easy target because he's an old, career minor leaguer, it's not like he traded roster spots with Vargas--if he had, the shade you're throwing the Twins would be a lot more founded. If your argument is: "I don't trust the Twins to handle player development," well then there's no discussion to be had, and let's leave it at that.
