Basallo (wrist) will start at catcher and bat fifth in Thursday's tilt versus the Mariners.
Basallo has been out of the lineup for the past three games as he deals with a bony growth in his left wrist, but he had a few plate appearances off the bench during that stretch and is now ready to return to the Orioles' lineup. The 21-year-old has collected a .801 OPS with nine home runs across 199 plate appearances for Baltimore this season.
