It should be an interesting off-season with all the money coming off the books and the additional leeway seeing the Braves won't be paying guys to play elsewhere next season (which makes the Kelenic deal look better). I've been complaining about the bench all year and I think keeping Alvarez around and have him develop a bit more at Gwinnett may be a strategy worth following. The Braves have been aggressive with him and that may have stunted him a bit as he moved to the AAA finishing school. He might be valuable as a three-position IF back-up in time. Same goes for Baldwin at catcher, whom I am more bullish about.
Of course, if someone bowls over the Braves with an offer and Alvarez is part of the package going elsewhere, they certainly have to consider it. That said, I don't see teams beating down the door for Alvarez. I think he's a mid-level prospect and those guys usually qualify as throw-ins. If the Braves move any of their prospects, I imagine it's going to be some of their second-tier pitching prospects (Hackenberg, Braun, Kuehler, etc.) unless, again, someone bowls them over and wants Smith-Shawver or Waldrep.
