Crooks will start at catcher and bat ninth in Wednesday's game against the Angels.
Crooks had been slated to sit for the second day in a row, but he'll end up receiving a turn behind the plate in the series finale after Pedro Pages (illness) was scratched just minutes before first pitch. The young backstop is hitting .176 with three home runs, nine RBI and four runs in 28 games since St. Louis called him up from Triple-A Memphis on May 29.
