Nunez has an 800 OPS this season. It will be hard for Arcia to top that. The Twins could go with two different semi-platoons in the outfield if they send back Santana and make Escobar the everyday SS. LF Rosario/Robinson CF Hicks (who platoons with himself) RF Hunter/Arcia They all bring different skill sets depending on defense, platoon advantage, contact v power, etc. I don't think the Twins are quite ready to bring up Arcia only to sit him on the bench most of the time. In September they'll be willing to do that. With the current roster you pretty much have to sit a prospect (Santana, Arcia, Rosario) in order to put together the best bench.
