In isolation, signing Park may not be bad (but signing a 29/30 yo unproven player to a four year deal, when your team has Plouffe, Mauer, Sano, Vargas, Arcia, ABWIII and Palka......well...who knows). In deciding to then not deal Plouffe, and putting Sano in the OF....well, that's not good. You need to look at the context of the move. Out of context, it looks like a great idea for most any move to add talent, but in context, that isn't always true. There are only 25 spots on the active roster, and 40 spots ovearall. There is only so much budget. So, I'm not sure signing Park was a good idea, in context of the Twins.
