The Seattle Mariners enter the offseason in a familiar position: competitive, talented, and close, but still searching for the kind of impact moves that can keep them on pace with the sport’s biggest spenders. With teams like the Toronto Blue Jays and Los Angeles Dodgers continuing to add star power after their recent World Series appearances, the pressure is on Seattle to be proactive if it wants to avoid falling behind in an increasingly aggressive American League landscape.
One of the clearest areas of need for the Mariners is at third base. Eugenio Suárez, who provided power and durability during his time in Seattle, remains a free agent, and while a reunion has not been ruled out, signs point toward the two sides moving in different directions. Suárez’s departure would leave a significant hole in the middle of the lineup, particularly in terms of home run production, something the Mariners have struggled to replace internally.
That uncertainty has fueled speculation about alternative solutions, and one of the more intriguing possibilities comes from SportsGrid’s Paul Connor. Connor has predicted that Seattle could turn to the international market and sign Japanese infielder Kazuma Okamoto as Suárez’s replacement. Okamoto is one of the most accomplished hitters in Nippon Professional Baseball and would represent a bold move by the Mariners, both financially and philosophically.
According to Jim Bowden of The Athletic, Okamoto is projected to command a contract in the range of $90 million in free agency. That price tag would mark a significant investment for a franchise that has traditionally operated below the top tier of MLB spending, but it would also signal a willingness to think bigger as the team’s competitive window remains open. At his best, Okamoto profiles as a middle-of-the-order bat with consistent power, plate discipline, and the ability to anchor a lineup, traits that would immediately address one of Seattle’s biggest weaknesses.
For the Mariners, the appeal of Okamoto goes beyond simply replacing Suárez. Adding a player of his caliber could help diversify the offense and reduce the burden on stars like Julio Rodríguez to carry the lineup every night. It would also continue a growing trend of MLB teams looking overseas for impact talent rather than limiting themselves to the domestic free-agent and trade markets, where prices and competition are often even steeper.
Of course, there are risks involved. Transitioning from NPB to MLB is never guaranteed, and committing $90 million to a player who has never faced major league pitching requires confidence in scouting, player development, and support systems. Seattle’s front office would need to be convinced that Okamoto’s skill set can translate quickly and that he can handle the expectations that come with replacing a well-known power bat like Suárez.
Still, the idea fits the broader conversation surrounding the Mariners this winter. With a strong core already in place, incremental moves may no longer be enough. To truly keep up with teams like the Dodgers and Blue Jays, Seattle may need to take a calculated swing on a high-upside acquisition. Whether that ends up being Kazuma Okamoto or another impact player, the message is clear: standing still is not an option.
As free agency unfolds, the Mariners’ next steps will reveal just how aggressive they are willing to be. A move for Okamoto would not only solve a pressing roster need, but also signal a shift in ambition, one that suggests Seattle is ready to push harder toward sustained contention rather than simply remaining competitive.
