Rojas isn't in the Mariners' lineup for Wednesday's game against Detroit, Shannon Drayer of SeattleSports.com reports.
Southpaw Tarik Skubal will toe the slab for the Tigers, which will send the lefty-hitting Rojas to the bench to begin Wednesday's contest. Dylan Moore will slide over to third base as a result, allowing Leo Rivas to pick up a start at shortstop.
