Mariners Focus on Third Base Upgrades This Offseason

The Seattle Mariners are actively seeking upgrades for multiple infield positions this offseason, with J.P. Crawford remaining their only confirmed starter at shortstop. The organization has shown strong interest in re-signing either Justin Turner or Carlos Santana to bolster their first base options. Meanwhile, they are also exploring various possibilities to strengthen their second and third base positions.

According to Ken Rosenthal of The Athletic, the Mariners are primarily focused on finding a new third baseman rather than a second baseman. Currently, the team has in-house options like Ryan Bliss, Dylan Moore, and top prospect Cole Young for second base.

At third base, the Mariners' prominent internal options include Moore and recent DFA acquisition Austin Shenton. Both Moore and fellow infielder Leo Rivas are better suited as utility players, with Moore potentially fitting into a short-side platoon role if the Mariners acquire a left-handed bat.

However, the Mariners face budget constraints this offseason. Despite an anticipated payroll increase in 2025, it is not expected to be substantial. Following the non-tender of players like Josh Rojas, Austin Voth, Sam Haggerty, and JT Chargois, Adam Jude of the Seattle Times estimates that the Mariners have around $16 million available for player acquisitions. Given this limited budget, it's unlikely the Mariners will make a significant splash in free agency for high-profile players such as Alex Bregman or Willy Adames. President of baseball operations Jerry Dipoto has historically preferred to operate through trades rather than free-agent signings, having only given one multi-year deal to a position-player free agent (Mitch Garver at two years and $24 million) in his nine years with the Mariners.

While trade options are not abundant, a few notable names are available. The Phillies have reportedly been shopping Alec Bohm, who, despite not being an elite hitter, offers a combination of affordability and potential defensive improvement. Bohm's projected salary stands at $8.1 million, making him a viable target for the Mariners. Additionally, former Mets top prospect Brett Baty could benefit from a change of scenery after the emergence of Mark Vientos. The Mets, who may allow Pete Alonso to depart in free agency and shift Vientos to first base, could be interested in acquiring a higher-profile third baseman, leaving Baty as a potential trade candidate.

​As the Mariners navigate their offseason strategy, fans can expect a combination of strategic trades and budget-conscious moves aimed at bolstering their infield and improving the team's overall performance for the 2025 season. Stay tuned for further updates as Seattle's front office works to enhance their roster and build a competitive team.
