Wetherholt is out of the lineup for Sunday's game against the Blue Jays.
Wetherholt will get his first day off since July 8 while the Cardinals go with Jose Fermin at the keystone. The NL Rookie of the Year frontrunner has been sluggish at the plate since the All-Star break, slashing .190/.292/.333 with three home runs, three steals, five RBI and 11 runs over 16 games.
