Ramirez is out of the lineup for Sunday's game against the Tigers, Tim Stebbins of MLB.com reports.
Ramirez appears to be receiving a planned day off after he had started in each of the Guardians' previous 12 games, including both ends of a doubleheader Friday. Angel Genao will check in at third base in place of Ramirez, who has gone 3-for-23 with one run and no RBI through the Guardians' first six games of September.
