The Seattle Mariners have spent years trying to crack the Japan market again, and the fit for their next swing at it might be sitting right there in Hanshin Tigers third baseman Teruaki Sato.
Seattle’s track record with Nippon Professional Baseball talent has been real enough. Ichiro Suzuki, Kazuhiro Sasaki and Hisashi Iwakuma all became important parts of the franchise’s story. More recently, Yusei Kikuchi was the last successful addition from Japan, though he’s better remembered for what came after his Mariners stint with the Los Angeles Angels.
Since then, the Mariners have come up short on a string of big names. Shohei Ohtani went to the Angels, Yoshinobu Yamamoto ended up with the Los Angeles Dodgers, Roki Sasaki never got to a sit-down meeting with Seattle, and Munetaka Murakami and Kazuma Okamoto landed elsewhere, with the Chicago White Sox and Toronto Blue Jays respectively.
That’s why Sato is worth keeping on the radar. He is expected to be posted this offseason and become available to MLB clubs, and he brings the kind of power that can change a lineup fast.
Over the last two seasons, the 27-year-old has hit 74 home runs and driven in 193 runs across 259 games. This season, he’s batting .324/.402/.638 with a 1.041 OPS in 120 games.
He also offers more than one defensive option. Sato can handle third base and either corner outfield spot, which gives a team room to maneuver. For Seattle, that kind of flexibility matters, especially with the possibility of fitting in top 100 prospect Michael Arroyo and utility player Brendan Donovan in 2027.
Of course, the picture could get crowded in a hurry if the Mariners keep veteran third baseman/shortstop J.P. Crawford or left fielder Randy Arozarena, and if former top prospect Colt Emerson comes back healthy and productive.
Seattle’s current third base picture hasn’t been stable either. Donovan, Emerson and Crawford have all missed time with injuries, and Emerson’s season ended after surgery for a displaced tendon in his wrist.
The raw production is easy to imagine in a Mariners uniform, especially after what Murakami and Okamoto have shown this year for their own clubs. Seattle can see the upside plainly enough.
There’s at least some reason to think Sato wouldn’t mind the idea, either. He has been spotted in past years wearing a Mariners hat during batting practice, and he once took a vacation to Seattle while dressed in gear from the city’s teams, including a Julio Rodriguez jersey.
For now, though, this is just a possibility. The Mariners haven’t been reported to have scouts at his games, and there’s also the chance that the whole offseason gets thrown into uncertainty if CBA talks between MLB and the MLB Players Association lead to a lockout.

Mariners Still Waiting As Brendan Donovan Hits A Recovery Roadblock
Brendan Donovans recovery has become a slower process than anyone around the Mariners likely hoped after the concussion he suffered Aug. 22 in the batting cages. He has continued to deal with symptoms such as dizziness and nausea, setbacks that have kept him from moving normally through the concussion protocol while the club waits for him to clear the next steps.
Donovan has been monitoring his recovery with a wearable device, and he confirmed he was not wearing a helmet when the injury happened. Mariners general manager Justin Hollander said Donovan is still not ready to return, leaving the team in the familiar position of waiting for a player whose timeline now hinges on symptoms easing before any real progress can be made.

Mariners Suddenly Have A 2027 Problem They Cant Ignore
The Mariners have spent much of this season trying to patch together a roster that keeps taking hits, and the latest setbacks only deepen the concern. Matt Brash has been shut down because of inflammation in his right lat, while Brendan Donovan is still making only gradual progress after the concussion he suffered on Aug. 21. Both absences matter right away, one affecting the bullpen and the other the lineup, but they also feed into a bigger question Seattle cant really avoid anymore.
What has made this stretch so tricky is that neither situation feels like a quick reset. Brash and Donovan have already missed significant time this year, and the uncertainty around when they will be back, and how dependable they will be when they are, puts real pressure on how the Mariners think about the next couple of seasons. It is the kind of lingering health issue that can change not just a month of baseball, but the shape of a 2027 plan. [Read more 🡒]
Mariners Fans Have A New Prospect Debate Worth Watching
Seattles recent wave of promotions has only sharpened the attention on what comes next, because there are still several high-end names in the system who look close enough to keep the conversation going. Ryan Sloan, Boston Smith and Jonny Farmelo are now the prospects Mariners fans are watching most closely, with each sitting in a different spot on the development curve but all carrying real major league intrigue as the organization keeps building toward the next batch of help.
The debate, of course, is less about whether theyll get there and more about who arrives first, and when. The timelines attached to Sloan, Smith and Farmelo stretch from late 2026 into mid-2027, which leaves plenty of room for their minor league performance to shape the picture before any official move is made. For a team that has already pushed a few top-100 talents to the majors in 2026, the next wave may end up being just as interesting as the first. [Read more 🡒]
