Mondesi is out of the lineup Saturday against the White Sox, Jeffrey Flanagan of MLB.com reports.
The 21-year-old is sitting for the third time in five games, and manager Ned Yost said that he's looking to get Whit Merrifield and Christian Colon more involved between second base and third down the stretch. Mondesi's defense has been excellent, but he's batting just .175/.223/.263 in 127 plate appearances.
