I really don't like this. Pompey is almost certainly better than Lake and Carrera, and a team's 4th OF gets almost full PT. If everyone is healthy:
Pompey starts 1-2 games a week in LF and Saunders sits against tough lefties.
Pompey starts 1-2 games a week in CF and Pillar gets a breather against top righties.
Pompey starts 1-2 games a week in RF and Bautista moves to DH or 1B.
And then you have pinch running/hitting duties, and more starts as guys get banged up.
