I think hitters do prefer to hit in certain spots in the lineup. I don't know about Smoak specifically, though.
Move Jose to lead off, Pillar to 8th, and move everyone else up one. So, Jose-JD-Morales-Smoak-etc. That seems to be the common sense move based on the talent involved. I'd be ok with Pearce at lead off too, but don't think Gibby has that faith in him yet.
