Motter is not in the lineup Tuesday against the Nationals, Shannon Drayer of 710 ESPN Seattle reports.
Motter has been a mainstay in the Mariners lineup for the past few weeks thanks to some injury woes plaguing Seattle, but with Robinson Cano returning from the DL and no DH available in Washington, Motter will head to the bench for a night off. The 27-year-old utility man has been struggling at the plate over the past few weeks, as he's batting just .200 over his past 30 games, so even when the Mariners return to American League action, it seems like he'll sit out more often than not until another injury strikes the Mariners' regulars.
