Mariners Sign Josh Naylor to Bolster Offense
The Seattle Mariners have made a major statement this offseason by signing Josh Naylor to a five-year, $92.5 million contract. This deal, finalized in November, gives the Mariners a much-needed left-handed power bat in the heart of their lineup. Naylor’s arrival is expected to address the team’s need for more consistent offense, especially after a 2025 season where run production was a concern. The Mariners hope that adding Naylor will provide a strong boost to their lineup and help them compete in a tough American League West. With Naylor now locked in at first base, the team has a clear plan for that position and can focus on other areas of need. The addition of Naylor and the commitment to improving the offense are two of the most important developments for the Mariners this winter.
Jorge Polanco Departs, Creating Infield Gap
The Mariners lost Jorge Polanco to free agency in early December, as he signed with the New York Mets. Polanco’s departure leaves a significant hole at second base, a position where the Mariners had relied on his steady defense and timely hitting. The team’s front office, led by Jerry Dipoto, has made it clear that filling this gap is a top priority. The Mariners have been linked to several trade targets, including Brendan Donovan of the St. Louis Cardinals and Ketel Marte of the Arizona Diamondbacks. Both players are known for their versatility and could provide the Mariners with much-needed stability in the infield. The loss of Polanco and the search for a new second baseman are shaping the team’s offseason strategy.
Trade Rumors Swirl Around Ketel Marte and Brendan Donovan
Trade talks have intensified as the Mariners look to upgrade at second base. Ketel Marte is a top target, and reports suggest the Mariners are among the teams most interested in acquiring him. Marte, an All-Star, brings a strong bat and the ability to play multiple infield positions. However, he has a limited no-trade clause and can block deals to five teams, though the Mariners are not on that list. Brendan Donovan is another option, offering a high on-base percentage and defensive flexibility. The Mariners’ pursuit of these players shows their commitment to improving the roster and making a push for the postseason in 2026. The front office is weighing the cost of these trades, as both players would require a significant return. The focus on Marte and Donovan and the potential for a major trade are key storylines to watch.
Mariners Out on Japanese Slugger Munetaka Murakami
The Mariners had been linked to Munetaka Murakami, a power-hitting infielder from Japan, but recent updates indicate they are no longer in the running. Murakami’s deadline to sign with an MLB team is December 22, but the Mariners’ commitment to Naylor at first base and their internal options at third base, such as Colt Emerson and Ben Williamson, make a deal unlikely. Most MLB teams view Murakami as a first baseman, and with Naylor signed for five years, the Mariners do not have a clear fit for him. If Murakami does not sign by the deadline, he will return to Japan for the 2026 season and could be posted again next offseason. The Mariners’ focus remains on finding a second baseman rather than adding another corner infielder. The end of Murakami rumors and the shift to internal options clarify the team’s direction.
Backup Catcher and Bullpen Depth Remain Under Review
The Mariners are also evaluating their options at backup catcher. With the offseason in full swing, the team is considering several candidates to provide depth behind the plate. This is a strategic move, as injuries and performance issues can quickly impact the catching position over a long season. In the bullpen, the Mariners have not made major additions yet, but the market for relievers has been active across the league. Notable deals include Edwin Díaz signing with the Los Angeles Dodgers and Kenley Jansen joining the Detroit Tigers. The Mariners may look to add a late-inning arm before spring training, especially with other American League teams strengthening their bullpens. The need for a backup catcher and the search for bullpen help remain on the team’s to-do list.
Recent Game Results and Offseason Activity
Since the end of the 2025 regular season, the Mariners have not played any official games. Their last game was on October 1, 2025, when they closed out the season with a win against the Texas Rangers. The focus since then has been on roster construction and preparing for the 2026 campaign. The team’s moves so far reflect a desire to build on last season’s progress and address key weaknesses. The Mariners’ front office has been active in trade discussions and free agency, signaling that more changes could be on the way before Opening Day. The final win of 2025 and the active offseason planning set the stage for the months ahead.
Jerry Dipoto Recognized for Executive Excellence
Jerry Dipoto, the Mariners’ President of Baseball Operations, received a well-deserved award this offseason for his work in building the team’s roster. Dipoto’s aggressive approach to trades and free agency has helped the Mariners stay competitive in recent years. His recognition highlights the organization’s commitment to improvement and the respect he has earned across Major League Baseball. Dipoto’s leadership will be crucial as the Mariners continue to pursue upgrades and aim for a return to the postseason. The honor for Dipoto and the focus on leadership are important for the team’s future.
Looking Ahead: Mariners’ Priorities for 2026
As the offseason continues, the Mariners’ main priorities are clear. They need to fill the gap at second base, add depth at catcher, and possibly strengthen the bullpen. The team’s pursuit of Ketel Marte and Brendan Donovan shows a focus on proven talent that can help right away. With Josh Naylor now anchoring the lineup, the Mariners are in a strong position to make further moves. Fans can expect more news in the coming weeks as the team prepares for spring training and the start of the 2026 season. The Mariners’ active approach this winter suggests they are serious about contending and building a roster capable of making a deep playoff run. The clear offseason priorities and the expectation of more moves will keep Mariners fans watching closely.
