I'd do it if I were you. your SP could use some help and you have pretty solid RP's after Marmol. Uggla will hit better so don't be concerned about that. Keep in mind if Zobrist hadn't blown up during that double header that one day, he would have stats on par with Uggla's current ones, only with a better avg and some sb's...
