Given the roster and the fact the Twins are in contention, I can't call for him playing every day but he should be in the lineup at least four times a week. If Mauer wasn't playing like vintage Joe Mauer right now, I might feel differently... and there's a good chance that doesn't last, which makes the decision to play Vargas easier. But given the fact the Twins are currently rostering Grossman, Mauer, and Vargas, none of them should be an every day regular. There are enough plate appearances to get them all reps multiple times a week and optimize the lineup based on opposing pitcher. In short, I want the Twins to win as many games as possible and getting Vargas somewhat regular playing time is a good way to get there but if Grossman and/or Mauer line up better against any single starter, I'm okay with sitting Vargas that day. The same goes for Mauer and Grossman, too.
