Neyer posted his thoughts on Pie.  I pretty much agree with his thoughts.   Some choice quotes.

 After 348 plate appearances, you want to see something from a guy who's been profiled as an every-day player and, just maybe, a future star.

Exactly, I'm not looking for a strong, or even average, performance now.  But an OPS+ of 27 is embarrassing. 

The "problem" is that Pie, in three Triple-A stints, posted a .300/.353/.478 line, and most of the time he was one of the younger players in the league. You can't give up on a guy like that. Not after 54 at-bats, nor after 348 plate appearances.

Exactly again.  If you're going to give him a chance, then at least let him get the majority of starts for another month or two.  That's probably not enough development time either but you can't let Reimold and Montanez tear up AAA w/o giving them a shot.  I'm surprised Rob didn't mention this, but I asked him in one of his chats if he thought Pie's bat could play in LF and he said no but the O's aren't contenders so they might as well develop him a young player like Pie especially his defensive skills.  Obviously Pie won't hit for an OPS+ of 27 for the rest of the season but he needs to start showing some sharp improvements fast.
