You know that feeling when the Northwest gray starts to feel permanent? That's usually when the first photos of green grass in Arizona start hitting the timeline. Honestly, the seattle mariners spring training schedule 2025 isn't just a list of dates. It's the annual proof that summer is actually coming back. This year, things at the Peoria Sports Complex have a slightly different vibe than the usual "hope springs eternal" routine.
There is a specific kind of pressure on this squad. After narrowly missing the playoffs again, fans aren't just looking for sun tans; they’re looking for a functional offense.
The 2025 journey officially kicks off on February 21. They are doing the usual thing where they open against their complex roommates, the San Diego Padres. It’s basically a home game without the travel, which is nice for the players’ legs. But for the fans, it's the first look at whether the bats have actually woken up over the winter.
Breaking Down the Big Dates
Most people just want to know when they can sit on a lawn with a hot dog. If you're planning a trip down to Peoria, the schedule is packed, but there are some specific windows you should aim for.
The Mariners are playing 33 games in 31 days. That is a lot of baseball. They’ve got four split-squad days, which means half the team stays in Peoria and the other half hops on a bus to somewhere like Scottsdale or Mesa. If you're buying tickets, double-check that the "star" players aren't the ones being shipped off to the away game that day.

Key Home Matchups in Peoria
- February 23 vs. Arizona Diamondbacks: Early test against the local favorites.
- March 7 vs. LA Dodgers: This is usually the hardest ticket to get. Expect a sea of blue in the stands.
- March 13 vs. Arizona Diamondbacks (Night Game): One of the rare 6:40 PM starts. The desert air feels amazing once the sun goes down.
- March 14 Spring Breakout vs. Cleveland: This is the one for the prospect nerds. It’s a showcase of the young talent like Colt Emerson and Cole Young.
Basically, the home schedule is a rotation of the usual Cactus League suspects. You’ll see the White Sox on March 1 and March 7, and the Brewers swing by on March 18 and 23.
The Pitching Lab and the New Faces
We have to talk about the rotation. It is, frankly, one of the best in baseball. Luis Castillo, George Kirby, Logan Gilbert—these guys are the reason Mariners fans haven't completely lost their minds. During spring training, these guys aren't usually trying to "win" games. They're working on specific grips or trying to see if a new sweeper actually sweeps.
But the real story this spring is at third base. With the addition of Donovan Solano and the return of Jorge Polanco, the infield is a bit of a puzzle. Dan Wilson, in his first full spring as manager, has to figure out how to shuffle these pieces. You'll likely see a lot of rotation between first, second, and third base throughout February and March.
Why the Spring Breakout Game Matters
A lot of people skip the prospect games. Don't do that this year. The Mariners currently have one of the highest-rated farm systems in the league. On March 14, when they face the Cleveland Guardians’ prospects in Goodyear, you’re looking at the future of the franchise. Guys like Lazaro Montes and Michael Arroyo are going to be household names soon. Seeing them in a low-stakes spring environment is kinda the best way to catch them before they're famous.

Logistics: Tickets and Timing
If you’re heading down, you've probably realized that Peoria isn't exactly a secret anymore. Single-game tickets went on sale back in December, but you can usually find some on the secondary market if you're willing to pay a premium for the shaded seats.
Pro tip: In Peoria, the sun is no joke. The third-base side gets the shade first. If you sit on the first-base side or the outfield grass, you are going to bake.
The typical first pitch is at 1:10 PM local time. Arizona doesn't do Daylight Saving Time, so the time difference between Seattle and Peoria changes mid-month. Usually, by the time games start, Seattle is one hour behind Arizona.
Watching from Home
Not everyone can fly to Phoenix. For those stuck in the rain, the broadcast situation is always a bit of a toss-up until the last minute. ROOT SPORTS usually carries a handful of games, and Seattle Sports 710 AM picks up the bigger matchups. If you have MLB.TV, you can often catch the "webcast" versions which are basically just the stadium feed with the radio audio over it. It’s better than nothing.

Navigating the Peoria Experience
Honestly, the best part of the seattle mariners spring training schedule 2025 is the accessibility. Unlike the regular season at T-Mobile Park, you can walk right up to the fences at the practice fields.
Most mornings, the players are out on the back fields by 9:30 or 10:00 AM. It is totally free to watch. You can see Cal Raleigh taking BP or Julio Rodriguez shagging fly balls from about twenty feet away. Just don't be that person screaming for an autograph while they're in the middle of a drill. Wait until they're walking between fields; most of them are pretty cool about it.
The Final Stretch
The schedule wraps up on March 24 against the Padres. After that, the team catches a flight back to Seattle. Opening Day is March 27 against the Athletics.
Spring training is long. It's a grind. By mid-March, players are usually ready to get out of the heat and play games that actually count. For us, though, it's the perfect bridge.
If you're planning your trip now, here's the reality: Peoria is crowded, the rental cars are expensive, and you’ll probably get a sunburn. But watching a Gilbert fastball pop the glove in the quiet of a half-empty stadium? There’s nothing like it.
Next Steps for Your Trip:
- Check the official Mariners spring page for any last-minute time changes.
- Book your parking in advance if you're going to a weekend game; the Peoria lots fill up fast.
- Download the MLB Ballpark app because the stadium has gone almost entirely paperless for tickets and concessions.
