Pillar is (errr should be) a very solid 4th OFer. Good defense, can play all 3 OF positions, runs well, hits lefties.....Nobody should be too upset that he's lined up to start in LF for a couple of weeks...this is exactly what a good 4th OFer does. I also expect Pillar to platoon with Saunders - especially early on when Saunders returns from the DL. That said - if he gets 500 at bats, he'll get grossly exposed (as do most 4th OFers).
Fans should get used to him....lets hope he doesn't s*** the bed early on b/c he's the best option we have.
