It all depends on who the Twins sign to DH. They will get some power there. And when did Graffanino become a guy with a lot of pop in his bat? In 379 AB's last season, Graffanino hit 7 homeruns. In 439 AB's last season, Castillo hit 4 homeruns. It's really not that big of a difference. Give me Castillo's much better OBP over Graffanino's few extra homers, especially if you are comparing them both as #2 hitters.
