Page Notes  
This is the current roster for the Seattle Mariners, as of today. TBC updates rosters once a day. The default view is the 40-man roster and to see the Active Roster or Injured players, you can use the filters above the grid. The 40-man roster is the protected roster of players eligible to be on the Active Roster without having their contract purchased while the 25-man roster is for players eligible to play in MLB games. Players on the 40-man have diferent player movement rules depending on their service time in the Majors or Minors. The Full season roster is a list of all players who have passed through the team's Active Roster, regardless of their current status.

In case of discrepancy between this page and MLB official roster page, please consider the MLB page correct. This is not an official roster page and is prone to missed transactions that will later be fixed when discovered.
