Marte exited Saturday's game with a sprained left thumb, but the Mariners have yet to announce the severity of the injury, Bob Dutton of the News Tribune reports.
Marte was replaced at shortstop by Shawn O'Malley after he appeared to jam his hand while stealing second base in the top of the fifth. There's still no word on whether Marte will need to miss additional time beyond Saturday, but if he does, O'Malley would likely continue to serve as his replacement at shortstop.
