Pillar is out of the lineup for Wednesday's game against the Tigers, Jeff Fletcher of The Orange County Register reports.
Pillar will head back to the bench after he had started in each of the Angels' previous four contests. The Angels faced one left-handed starter (Brant Hurter) during that stretch, and Mickey Moniak also missed two games with an elbow injury, so despite what his recent usage might suggest, Pillar still looks to be stuck in a fourth-outfielder role.
