Saunders (oblique) went 1-for-4 with a walk in his first rehab game at Triple-A Tacoma on Thursday. Most likely, Saunders will remain on a rehab assignment throughout the weekend before returning to the Mariners' outfield early next week. He'll likely end up on the better side of a platoon in one of the corner outfield spots upon activation, yielding time against lefties to recently acquired veteran Chris Denorfia.
