After recalling left-hander Ariel Miranda to replace an injured Drew Smyly in the rotation, the Mariners moved to set their roster Friday for a regular season that begins Monday at Houston.
Final decisions aren’t required by clubs until noon Pacific time Sunday, but the Mariners appear ready to open the season with an eight-man bullpen that actually won’t have eight relievers.
Lefty starter Dillon Overton will break with the club as the bullpen’s long reliever. How long he remains in that role is uncertain, but the Mariners seem likely to make several tweaks to their roster throughout April.
