Fermin will start in center field and bat seventh in Wednesday's game against the Angels.
Though he'll draw back into the starting nine while southpaw Reid Detmers takes the hill for the Angels, Fermin appears to have lost hold of a regular spot in the lineup against right-handed pitching. The Cardinals kept him on the bench when the Angels sent righties to the bump for the first two contests of the series, with Blaze Jordan getting the nod over Fermin at third base in both games.
