Wainwright, who was scheduled to start Saturday's Grapefruit League game against Houston, will now pitch in a game on a back field, Derrick Goold of the St. Louis Post-Dispatch reports.

EDGE Analysis

Due to a threat of inclement weather Saturday, the Cardinals will alter Wainwright's pitching plans to make sure that he's able to pitch. Saturday's session will serve as a final tune-up for the right-hander before he starts in the Cardinals' Opening Day matchup against the Pirates on Thursday.
