Valencia (wrist) is back in the lineup Tuesday against the Nationals, batting sixth and playing first base, Shannon Drayer of 710 ESPN Seattle reports.
Valencia missed the past two games due to a sore wrist, but after an MRI revealed that there was no structural damage, the Mariners will slot him right back into his normal spot in the lineup. However, the 32-year-old has been in a slump at the plate as of late, picking up just three hits in the past seven games.
