Winn has been absent from the Cardinals' lineup the last two days because of left thumb irritation, Derrick Goold of the St. Louis Post-Dispatch reports.
Winn injured the thumb Wednesday in Cincinnati when he jammed it into a base. The slick-fielding shortstop has appeared in both games off the bench, indicating that he should be ready to return to the lineup soon. The Cardinals have been covering for Winn by shifting JJ Wetherholt over to shortstop and starting Bryan Torres at second base.
