I think he would understand that all of their chips rest with Joe Mauer, their No.1 overall pick, hometown boy, top prospect, etc.
I am sure he didn't like to be traded and such, but I am sure he understands the reason why and doubt this would be a move to stick it to the Twins.
Had the Twins not drafted Mauer, Pierzynski would still be in Minny being a Sox killer.
Book it.
