Walker is out of the lineup for Wednesday's game versus the Pirates.

EDGE Analysis

Walker started in each of the previous four games, which had been preceded by a four-game stretch when he made only one start. The 23-year-old is slashing just .234/.269/.297 in August and .231/.285/.318 on the season. Lars Nootbaar will handle right field and Nathan Church will play center field for the Cardinals on Wednesday.
