The offseason felt short. That’s what happens when you push all the way to Game 7 of the ALCS.
Now the reset button has been hit. Spring Training is here. And for the 2026 Seattle Mariners, this camp isn’t just about getting loose in the Arizona sun. It’s about defining roles, identifying depth, and figuring out whether last year’s postseason run was the beginning of something bigger.
Here’s what actually matters.
Mitch Garver Is Back — And That Matters More Than You Think
Mitch Garver returns on a minor league deal. On paper? Not flashy. His production last season did not match the price tag.
But that isn’t why this move matters.
Behind the scenes, Garver was a clubhouse stabilizer. Pitchers trusted him. There were reports that arms like Logan Gilbert specifically preferred working with him. That kind of buy-in from your rotation is not accidental.
Now the financial risk is gone. The upside remains.
If he wins a job? Great.
If he becomes Triple A depth and a mentor? Still valuable.
For a team trying to keep its ALCS core intact, this is a low-risk culture play.
The Dane Dunning Question
Dane Dunning is one of the more fascinating Spring Training storylines.
Is he rotation depth?
Is he long relief?
Is he a bullpen weapon in disguise?
The numbers last year were fine. Not dominant. Not disastrous. But here’s what jumps out: the strikeout rate. He has swing-and-miss ability.
And this organization, under Jerry Dipoto, has a track record of identifying pitchers with one standout trait and optimizing them. We’ve seen it before. A 7+ ERA somewhere else becomes a bullpen weapon in Seattle.
Spring Training won’t decide everything. But it will show us:
• Is the velocity ticking up?
• Is the command sharper?
• Does he look comfortable attacking hitters?
Stats in February lie. Mechanics and confidence do not.
Brendan Donovan’s Fit
Brendan Donovan in a Mariners uniform still feels new.
He’s not the flashiest name. He’s not a 40-homer bat. But what he brings is lineup flexibility and situational awareness.
Spring Training gives us a look at:
• Defensive versatility
• Where he slots in the batting order
• How he blends into a clubhouse that just tasted October pressure
Sometimes the most important additions are the ones that don’t need headlines.
The World Baseball Classic Factor
World Baseball Classic creates a unique wrinkle this year.
The Mariners are sending more players than ever before. That means two things:
- Established starters may see limited early reps.
- Prospects will get extended opportunities.
This is huge.
Spring games could feature real lineup combinations with legitimate prospect exposure. That kind of stage matters for development and evaluation.
If you’re paying attention, this is where future depth pieces reveal themselves.
The Prospect Watch List
One name that keeps coming up: Lazaro Montes.
There’s raw power there. Legitimate middle-of-the-order upside. You don’t see bats like that often.
Then there’s the pitching side. Ryan Sloan. Kate Anderson. Arms that are starting to buzz within the system.
But Spring Training isn’t always about the hyped names.
Every year, someone unexpected pops.
That’s what makes this stretch compelling.
A Sneaky Arm to Watch
Josh Simpson isn’t lighting up stat sheets historically. But 36 strikeouts in 30 innings last year tells you something.
Miss bats first. Refine everything else later.
If Seattle’s pitching lab gets its hands on him and finds a niche role, don’t be surprised if he becomes a midseason bullpen conversation piece.
The Bigger Picture
This Spring isn’t about proving the Mariners belong.
They proved that last October.
It’s about refinement.
• Can the pitching depth hold up?
• Can the offense sustain?
• Can young players push veterans?
• Can the organization maintain hunger after its deepest run ever?
Seattle is not used to this level of sustained sports optimism. The city is riding high. But baseball has a way of humbling momentum.
Spring Training won’t answer everything.
But it will tell us:
Who’s sharp.
Who’s confident.
Who’s ready.
And for a team trying to go from contender to consistent powerhouse, that’s where it starts.
