Mondesi is out of the lineup Thursday against the Rays, MLB.com's Jeffrey Flanagan reports.
After notching six hits in his first five games after being called up on July 26, he has now gone hitless with five strikeouts over his last four contests. Mondesi's defense alone should keep him in the lineup most days, but Christian Colon will man the keystone Thursday to give the 21-year-old rookie a day off.
