Ideally for me, they don't keep him on the playoff roster, and he just sits in the dugout with the other cheerleaders. But it's possible he ends up being the "extra" guy. Either way I doubt he pitches.
Pillar is a bad hitter, that never changed. He swings at garbage. Recently he's gotten lucky and more of his garbage swings have resulted in hits. It reeeaaally won't make a difference if he gets an extra day or two off. I'd rather him nurse whatever bumps and bruises he has while we have the opportunity, and if we can get a look at Pompey in CF in the meantime, cool.
