Mariners 2021 roster tracker: Who’s in, who’s out and who’s staying in Seattle

The baseball offseason is here, meaning Mariners general manager Jerry Dipoto will surely be looking for a few more pieces to fill out this already thriving young roster, which finished just short of the postseason in an abbreviated 2020 season.

If the Mariners are planning to make a playoff push in 2021 — which Dipoto said in September he thinks is a realistic goal — they’ll seek to add more experience and depth to the young group already in Seattle, and the next wave of prospects expected to arrive soon.

“We intended to build something that has lasting sustainability, and I think that’s that’s getting closer and closer every day,” Dipoto said.

This page will be updated throughout the offseason as the Mariners make roster moves to let you know who’s in, who’s out and who’s staying in Seattle.
