Jack Larsen has been shut down due to a hamate bone injury.
It’s unclear if he’ll end up needing surgery, but either way it sounds like it will be a while before he returns to game action. Larsen, 28, struck out in his lone plate appearance with the Mariners last season (his MLB debut) after spending five seasons in the minors. Assuming he bounces back to full health, he’ll serve as upper-level outfield depth in Seattle’s minor league system.
