I really don't like the idea of Pinto in the outfield at the same time as Arcia, but there may be ways to get his bat in the line up without sacrificing the little outfield defense we have. I propose he scrape together starts from several different places:
1) Pinto acts as the backup catcher to Suzuki, gets two starts/week behind the plate (over a whole season this acconts for roughly 50 games).
2) Mauer will probably sit out at least 20 games, during these games Vargas plays 1B and Pinto DHs.
3) Pinto and Arcia get placed in a platoon, either directly or indirectly. Although I think he's improved a little bit, Arcia still does not seem capable of putting up solid numbers against LHP. Rather than force Arcia to stay in the lineup and struggle I think the Twins are better off putting either Pinto or Mauer (obviously defense would be better with Mauer) in RF against LHP. Depending on who's in RF, this puts either Mauer or Vargas at first with either Vargas or Pinto DHing. This part is a total guess, but say 25-30% of games played are started by a lefty, this accounts for a little over 40 games started by Pinto per year (we'll say 40 as there would probably be some overlap with the other two options.
All in all, we are looking at Pinto starting 110 games in a season, which would definitely be better than the playing time he was seeing this season. The only problem is Gardy would never go for this without a third catcher, so either the Twins need to get a new manager who doesn't have an irrational fear of playing both catchers in the same game, or we would need a third catcher on the roster. As much as I'm opposed to three-catcher rosters, I prefer them to 13-man bullpens...
