Find me a quote that says otherwise, but I believe he was slated to platoon with Ryan Freel in left, facing RHP. Or so their bonehead Cubs retread GM Andy Macphail said anyway.
I didn't realize he was having such a bad spring. Although, when your alternative is Ty Wigginton, who has no upside at this point and is a what you see, what you get type of player, AND you're going to be a 3rd or 4th place team... I think I would start Pie and roll with it. He's tapped out in the minors, he isn't going to get any better down there... he needs to face big league pitching & big league breaking balls. He's out of options anyway, so they'll atleast be forced to carry him (or so I would hope...)
