Seattle, WA – The Seattle Mariners are entering the 2026 offseason with a clear message: keep up with the league’s biggest markets or risk falling behind. Despite a talented core of players, including Julio Rodriguez, Cal Raleigh, and Josh Naylor, the Mariners face the critical task of filling the void left by Eugenio Suárez, who is now a free agent. With Toronto and Los Angeles enhancing their rosters after deep playoff runs, the Mariners know the clock is ticking.
Sources close to the team suggest Seattle has set its sights on an audacious target: Kazuma Okamoto, the international free-agent infielder from Japan’s Nippon Professional Baseball (NPB). According to SportsGrid analyst Paul Connor, the Mariners are prepared to offer a staggering $90 million contract to bring Okamoto stateside, a projection confirmed by Jim Bowden of The Athletic.

Connor highlighted Okamoto’s potential impact: “Power-hitting infielder from NPB with a track record of strong on-base skills and plus raw power; hit .327/.416/.598 with 15 HR in 69 games in 2025; potential adjustment risks to MLB velocity.” In other words, Okamoto brings the kind of offensive firepower the Mariners desperately need, but there are questions about how quickly he can adapt to the faster, more unpredictable pitching in Major League Baseball.
History, however, shows that top NPB talent often adjusts remarkably well. From Ichiro Suzuki to Shohei Ohtani, Japanese stars have made immediate impacts in MLB, silencing skeptics who worry about the learning curve. Okamoto, widely regarded as one of the best hitters available in this free-agent cycle, could follow the same trajectory.
Seattle presents a particularly favorable landing spot for the 29-year-old slugger. The Mariners’ lineup is stacked with young, dynamic hitters who can complement Okamoto’s skill set. Picture this: Okamoto stepping into the middle of a batting order already anchored by Rodriguez’s elite contact skills, Raleigh’s power, and Naylor’s versatility. Adding Okamoto could transform Seattle’s offense from dangerous to virtually unstoppable.
For a franchise still chasing its first World Series title since 2001, this move would signal a bold commitment to winning now. The Mariners are no longer content with developing talent slowly—they need instant impact players who can help them compete against juggernauts like the Blue Jays and Dodgers.

Yet, the decision isn’t without risk. Signing a $90 million international free agent comes with high stakes. If Okamoto struggles to adjust, the financial commitment could weigh heavily on the team. But Mariners management appears confident in their scouting and development system, which has already nurtured young stars into elite performers.
Analysts are already buzzing about the potential ripple effect of landing Okamoto. Not only would it solidify the infield, but it would also create a lineup that blends power, on-base skills, and versatility, making Seattle a serious contender in the American League West. Fans, meanwhile, are imagining the kind of highlight-reel moments that could redefine Mariners baseball for the next decade.
The timing could not be more critical. With Suárez moving on, the Mariners need to act fast before other MLB teams swoop in. The combination of Okamoto’s proven NPB success, Seattle’s offensive needs, and the $90 million valuation makes this one of the most talked-about potential signings of the offseason.

If the deal comes to fruition, it could mark a turning point for the Mariners franchise. It would demonstrate that Seattle is willing to compete financially with the league’s heavyweights while also betting on a player with elite international pedigree. For a team eager to translate young talent into championships, landing Okamoto may be exactly the move that puts the Mariners back on the map—and keeps fans glued to every pitch.
As free agency unfolds, all eyes will be on Seattle. Will Kazuma Okamoto make the leap to MLB and join the Mariners’ star-studded lineup? Or will the hefty price tag and adjustment concerns hold the team back? The answers in the coming weeks could redefine the trajectory of the Mariners for years to come.
