Among the outfielders, it's safe to say Buxton isn't going anywhere and Kepler has the next best outlook as a starter in the long term. Getting one passable starter and one good bench player out of the three of Arcia, Grossman, and Rosario seems like a reasonable goal. Grossman's career has a bit more of the "failed prospect" trajectory than Arcia or Rosario's at this point, but he's not that much older than them, and useful players arrive in different ways, including as ex-prospects putting it together later on. IMO it should be an open competition between those guys for those spots. Santana seems more dispensable--fine to keep him around if they can use him, but no big loss if he gets cut for reasons of roster crunch. Similar case with Vargas. Echoing the thread about trading Nunez, if some team wants to buy high on his hitting these last couple months, great, trade him; if not, he probably doesn't have great trade value and the Twins are in as good a position as any team to see how long he can sustain it. Yeah, not a good defender, but his ability to fill in at multiple positions has value, as does being a backup without a complete zero for a bat if putting Sano back at 3B or Polanco wherever doesn't work as hoped.
