I agree with a lot on here.
I think Buxton goes to IL when Polanco gets called up. That solves some problems. While Royce hasn't been reliable from a health standpoint, I don't see the Twins making a move at 3B unless they can for something very cheap. Dumping Gallo seems like a smart move but I don't believe the Twins are an organization who will do that. Kepler isn't the problem but he also isn't really an answer. I think the group/success of Correa, Polanco, Kirilloff, Julien, Lewis/Solano getting consistent work is probably the best road to success for the rest of the year. I don't know how that works with Buxton not being able to play CF. The Buxton decision is baffling to me but I know that has been talked about enough.
Ultimately, I would have no problem with the Twins making a move for a good, young player. However, those opportunities are few and far between. Yes, adding a right handed bat, a better 3B, and bullpen help would be nice but it comes down to what you have to give up.
