Mariners President Jerry Dipoto says Seattle isn't done dealing, but a slow market has cooled down the Hot Stove League

Jorge Polanco is reportedly signing with the Mets, which brings uncertainty and opportunity to the Seattle Mariners' offseason, insider Shannon Drayer reports.

The Seattle Mariners have emerged as a top suitor for a Japanese star slugger amid Eugenio Suarez’s free agency.

Seattle added to its minor league ranks with multiple selections in the Rule 5 draft Wednesday at the MLB winter meetings in Orlando, Fla. The Mariners opted not to take a player in the major league portion of the Rule 5 draft, which would have forced the team to keep the draftee on their major league roster for all of 2026.

While the Seattle Mariners continue to look for a veteran infield bat, the roles for their younger infielders in 2026 are clearing up.

The Mariners have found their leading candidate to be their backup catcher in 2026. The club is nearing an agreement on a Major League contract with veteran backstop Andrew Knizner, sources told MLB.com on Friday night,

Prior to the start of the MLB Winter Meetings, the Seattle Mariners traded away catcher Harry Ford, who was projected to be the backup catcher behind Cal Raleigh heading into 2026.

If Ferrer takes steps forward in his development, he could provide the Mariners another legitimate high-leverage option, says Rick Graham of Pitcher List.

Seattle Mariners are eyeing Matt Strahm of the Philadelphia Phillies. This move aims to strengthen Seattle's bullpen for the 2026 season. Strahm is a reliable high-leverage arm. The Mariners seek left-handed depth.
