As the cool October air sweeps across downtown Detroit, the stage is set for one of the most important games of the season. The Detroit Tigers and Seattle Mariners are locked in a fierce battle in the 2025 American League Division Series (ALDS), and tonight’s Game 4 could determine everything.
For Seattle, it’s a chance to punch their ticket to the American League Championship Series (ALCS) for the first time since 2022. For Detroit, it’s survival — a do-or-die opportunity to keep their Cinderella season alive in front of a roaring home crowd at Comerica Park.

Series Overview: The Tension Is Real
After three games, Seattle holds a 2–1 series lead. The Mariners took the opener in dramatic fashion before Detroit roared back in Game 2 behind stellar pitching. But Game 3? That belonged to Seattle again, thanks to Julio Rodríguez’s two-run blast and some late-inning heroics from Andrés Muñoz out of the bullpen.
Now, Game 4 becomes the pivot point. Seattle can close it out and move on. Detroit has to find a way — any way — to force a decisive Game 5 back in Seattle.
The mood in Detroit is intense. Fans have packed Comerica Park hours before the first pitch, waving orange towels and chanting for one more win. After all, this is a city that has waited more than a decade to see playoff baseball return to relevance.
Probable Starters: Mize vs. Miller
Detroit Tigers – Casey Mize (RHP)
Casey Mize, the former No. 1 overall pick, takes the ball for the Tigers. Mize has been solid all season, posting a 14–6 record with a 3.87 ERA, but his biggest challenge has always been the long ball. The Mariners are a power-heavy team, and Mize’s ability to keep the ball down will be critical.
Pitching coach Chris Fetter said earlier this week, “Casey’s stuff plays when he’s ahead in the count. He can’t nibble. He’s got to trust that fastball.”
Mize will be pitching on six days’ rest, which could work in Detroit’s favor — he’s typically sharper when fully recovered.
Seattle Mariners – Bryce Miller (RHP)
On the other side, it’s Bryce Miller, making his first postseason start. Miller’s regular season was uneven — 4–6 with a 5.68 ERA — but Seattle believes in his raw stuff. His fastball touches 98 mph with late life, and when his slider is working, he can miss bats in bunches.
With Bryan Woo sidelined due to a pectoral injury, Miller was the logical (if risky) next man up. Manager Scott Servais said, “We believe in Bryce. He’s got the stuff to get us 12 big outs. After that, we’ll go to the bullpen.”
What’s at StakeIt’s easy to overlook, but this matchup is historic in its own way. The Tigers haven’t reached the ALCS since 2013, when Miguel Cabrera, Max Scherzer, and Justin Verlander were still wearing the Old English “D.” The Mariners, meanwhile, are trying to prove that their 2022 breakthrough wasn’t a fluke.
If Seattle wins tonight, they’ll be just four victories away from their first World Series appearance since 2001. For Detroit, it’s about fighting back — showing that this young core (Torkelson, Greene, Keith, and Mize) is ready for the big stage.
Key Storylines to Watch
1. Can Detroit’s Offense Wake Up?
In Game 3, the Tigers managed only five hits and struck out 12 times. Spencer Torkelson has done his part, collecting two home runs in the series, but he can’t do it alone. Riley Greene has been quiet, and Kerry Carpenter’s power hasn’t shown up since September.
Manager A.J. Hinch hinted at lineup tweaks, saying, “We’ve got to be more aggressive early in counts. When you fall behind against Seattle’s bullpen, it’s game over.”
2. Julio Rodríguez vs. Casey Mize
This is the heavyweight battle to watch. Rodríguez has been electric this postseason, batting .364 with two homers and five RBIs. Mize has struggled against right-handed power hitters, so expect Detroit to pitch around Julio whenever possible.
If Rodríguez gets a fastball over the plate, the crowd might not even have time to sit down before it’s gone.
3. Bullpen Chess Match
Seattle’s bullpen has been borderline elite this October. Andrés Muñoz has thrown four scoreless innings with eight strikeouts, while Matt Brash has been nearly unhittable. Detroit, meanwhile, will lean on Alex Faedo, Will Vest, and closer Jason Foley to lock down the late innings.
Because this is a day game following a night game, expect both teams to be quick on the hook. If either starter runs into trouble early, the bullpen carousel could start spinning by the fourth inning.
4. Home Field Energy
Detroit hasn’t won a postseason game at Comerica Park since 2013 — a streak the team desperately wants to break. The crowd has been electric all week, and players have acknowledged the difference.
Riley Greene said after Game 3, “We owe it to these fans. We’ve just got to give them something to cheer about.”
Live Updates (Pregame Through Mid-Game)
Pregame (2:00 p.m. ET)
Comerica Park is buzzing. Fans are pouring in early, and Tigers players are taking batting practice under bright blue skies. The weather is perfect for October baseball — 67°F and sunny, with a light breeze blowing in from left field.
Top 1st
Casey Mize opens the game with a 95-mph fastball that paints the inside corner. Julio Rodríguez works a deep count but grounds out to short. A good sign early — Mize looks locked in.
Bottom 1st
Detroit threatens early. Kerry Carpenter singles to right, and Gleyber Torres draws a walk. But Miller escapes the jam, striking out Torkelson with a high fastball. The crowd groans — that’s one the Tigers needed.
Top 3rd
Seattle draws first blood. Cal Raleigh unloads on a hanging splitter, sending it 414 feet into the right-field seats. Mariners lead 2–0. Mize slaps his glove in frustration — that pitch simply caught too much plate.
Bottom 4th
The Tigers respond. Riley Greene doubles off the wall, and Torkelson follows with an RBI single through the left side. Mariners 2, Tigers 1. Comerica Park comes alive again.
Middle Innings
The bullpens take over. Both starters exit by the fifth inning, and the relievers keep things tight. In the seventh, Julio Rodríguez doubles but is stranded as Jason Foley induces a big groundout to end the inning.
Late-Inning Drama
By the eighth, tension fills every corner of Comerica Park. The Tigers trail 3–2 after a solo homer by Eugenio Suárez, and Seattle turns to its closer, Muñoz, for a six-out save.
Detroit fights back in the bottom of the eighth — a leadoff single from Báez, a sacrifice bunt from Carpenter, and then a massive two-out hit from Colt Keith ties the game at three. The stadium erupts.
It’s baseball at its purest: two teams trading blows, every pitch carrying weight.
If this game ends the way many expect — a nail-biter decided by one swing — it will perfectly encapsulate what this series has been all about: grit, patience, and the thin line between triumph and heartbreak.
Whether Detroit forces Game 5 or Seattle seals the deal, both teams have proven they belong here.
(Live final score and postgame details will depend on the actual result once Game 4 concludes.)
What Comes Next
If the Tigers win, the series returns to Seattle for a decisive Game 5 on Friday, October 10. The pitching matchup would likely feature Detroit’s Reese Olson against Seattle’s Luis Castillo — a showdown between power and precision.
If the Mariners win, they’ll advance to face either the New York Yankees or Houston Astros in the American League Championship Series, starting Saturday.
Either way, the ALDS has delivered everything October baseball promises — drama, tension, and unforgettable moments.
