The 2025 Seattle Mariners seemed like a team of destiny at times, to the point where their first-ever World Series appearance almost felt like a sure thing.
But it was not to be. Even after 60 home runs from Cal Raleigh, a 30-30 season by Julio Rodríguez and a wildly productive trade deadline led to 90 wins and an AL West title 24 years in the making, the Mariners still bowed out of the playoffs in the ALCS after falling to the Toronto Blue Jays in seven games.
The Mariners head into the offseason knowing that they have the foundation to contend again in 2026. Raleigh and Rodríguez are going nowhere, and they also stand to return all five of their core starting pitchers and one of MLB’s best closers, Andrés Muñoz. Further, they’re sitting on the league’s No. 1 farm system.
Many holes will have to be filled, however, including several in a lineup that was arguably the deepest in the American League by the end of the season. And for the president of baseball operations, Jerry Dipoto, the challenge is always how to make the most of a mid-sized budget.
Ahead, we’ll get into which Mariners stand to become free agents and mull potential targets on the free-agent and trade markets, culminating in a prediction for what their 2026 roster will look like.
