Honestly, it feels like every winter in Seattle follows the exact same script. We spend October mourning a "so close" finish, November checking Jerry Dipoto’s trade odometer, and January frantically refreshing Twitter to see if the front office actually has any money left under the mattress.
But this year is different.
After falling just eight outs short of a World Series appearance in 2025, the vibe around the Seattle Mariners news rumors mill isn't just about "building a contender" anymore. It’s about finishing the job. We’ve seen the big first step: locking down Josh Naylor on a massive five-year, $92.5 million deal. That was the easy part. Now, things are getting weirdly complicated.
The Brendan Donovan Drama is Peaking
If you’ve been following the rumors for more than five minutes, you know the Mariners have been obsessed with St. Louis Cardinals infielder Brendan Donovan. He’s the perfect Dipoto player—high contact, versatile, and basically the anti-strikeout machine this lineup has lacked for a decade.
For a while, it looked like a lock. Then the Chicago Cubs went and blew up the market by giving Alex Bregman $175 million.
Suddenly, everyone needs an infielder. The San Francisco Giants have reportedly jumped into the Donovan sweepstakes with "aggressive" intent, according to Jeff Passan. The Mariners have been hesitant to move their precious "Major League ready" young pitching—guys like Bryce Miller or Bryan Woo—and that hesitation might be what lets the Giants steal him away.
St. Louis isn't looking for mid-tier prospects anymore. They want the arms.
What’s the Deal With the Payroll?
There is this persistent myth that the Mariners are broke. They aren't.
Jerry Dipoto mentioned back in October that the 2026 payroll would likely start around where 2025 ended, which was roughly **$165 million to $166 million**. Right now, with the arbitration raises for Randy Arozarena ($15.65M) and Logan Gilbert ($10.9M) officially on the books, the commitments are sitting around $153 million.
That leaves about $12 million to $15 million in "safe" wiggle room.
If John Stanton gives the green light to push toward $180 million, the Mariners are major players for another big bat. If he doesn't? They’re basically hunting for bargains or banking on 20-year-old Colt Emerson to be the second coming of Corey Seager the moment he hits Peoria.
The Ketel Marte "Pipe Dream"
We have to talk about Ketel Marte because his name keeps popping up in Seattle Mariners news rumors like a ghost that won't leave.
Arizona reportedly pulled him off the market recently, which sent a shockwave through the M’s fan base. But here’s the thing: in baseball, "off the market" usually just means "you haven't offered us enough yet."
The D-backs are looking for a haul that would likely include a combination of Harry Ford (who was already traded to Washington for Jose Ferrer, by the way) and top-tier pitching. Since Ford is gone, any deal for a superstar like Marte would require the Mariners to gut the rotation. Are you willing to trade George Kirby for two years of Marte? Most people say no. The front office definitely says no.
The Infield Gap Nobody is Talking About
Everyone is focused on second base, but third base is a giant question mark.
Eugenio Suarez is still sitting out there in free agency. There’s been talk of a "reunion," but the Mariners seem more interested in internal options like Ben Williamson or even moving Luke Raley around.
The most realistic scenario? Seattle waits for the Bo Bichette market to settle. Once the top-tier shortstops and third basemen find homes, the price on a veteran like Suarez or even a trade for someone like Nico Hoerner (if the Cubs decide to move him after the Bregman signing) becomes much more manageable.

Quick Roster Realities
- The Rotation is Untouchable: Unless it's for a literal MVP, Gilbert, Kirby, and Castillo aren't going anywhere.
- The Naylor Effect: By signing Josh Naylor early, the Mariners signaled they are "win-now," which actually hurts their leverage in trades. Teams know they’re desperate for that one last piece.
- The "Mystery" Option: Don't sleep on Munetaka Murakami. The Japanese slugger has been linked to Seattle for months, though that feels like a 2027 move more than a right-now move.
Real Actionable Insights for the 2026 Season
If you're trying to figure out how this roster actually shakes out by Opening Day, stop looking at the "superstar" free agents. This front office doesn't shop at the top of the market; they shop for value and control.
- Watch the "Infield Surplus" Teams: Keep an eye on the Cubs and the Rays. Both teams have more middle infielders than they have starting spots. A trade for Nico Hoerner or Brandon Lowe is far more "Mariner-like" than a $100 million free agent splash.
- Monitor the Relief Market: The Mariners non-tendered Gregory Santos and lost Mitch Garver (mutual option declined). They need high-leverage arms. Expect a flurry of minor league deals with invites to Spring Training for veteran relievers coming off injury.
- The Colt Emerson Factor: If the Mariners don't make a trade by February 1st, it means they are 100% committed to letting the kids play. Emerson and Cole Young are the future, and the team might prefer to "fail" with them than overpay for a 31-year-old stopgap.
The next few weeks will be telling. If the Giants land Donovan, the pressure on Dipoto to pivot to a "Plan B" trade will be immense. Seattle fans are patient, but after coming so close last year, "wait and see" won't fly in the 2026 season.
Next Steps for Fans: Check the 40-man roster flexibility. The Mariners currently have a few open spots after the non-tender deadline, which suggests they are clearing room for a multi-player trade. If you see them DFA a fringe reliever in the next 48 hours, a bigger move is likely brewing. Stay focused on the Cardinals and Cubs—those are the two teams that hold the keys to the Mariners' infield.
