Mariners vs. Tigers Gameday
Game 3 of the ALDS shifts to Comerica Park, where the Seattle Mariners and Detroit Tigers are knotted at 1–1 in this best-of-five showdown.
The Tigers took Game 1 by a run before the Mariners answered in Game 2, setting up a pivotal swing game under cloudy skies and a light Detroit drizzle. First pitch is set for 4:08 PM ET on FS1.
Seattle enters with a 90–72 record and one of the best divisional marks in baseball (34–18). Under manager Dan Wilson, the Mariners have leaned on power and pitching balance to stay alive.
After leveling the series, they’ll look to steal one on the road now.
A.J. Hinch’s Tigers (87–75) finished just one game out of first in the AL Central and now return to their home turf, where they went 46–35 this year.
Detroit’s lineup has found timely hits all season, and with the Comerica crowd behind them, they’ll try to grab back momentum in front of their fans.
The postseason matchup has been tight — both games decided by a single run and staying under the total. Seattle dominated the regular-season series 4–2, but Detroit has held its own this October.
With the series hanging in the balance, expect another tense duel in Motown.

Seattle Mariners vs. Detroit Tigers Odds & Last 5
Oddsmakers give the edge to Seattle for Game 3, listing them at -132 on the moneyline, while Detroit sits at +112 as home underdogs. The total is 7.5, with the under slightly shaded (-117).
Each of the first two games has finished under the number, and both were decided by a single run — a clear sign of how evenly matched these teams are. The Tigers have won three of their last five overall, while the Mariners snapped a short skid with their Game 2 win.
During the regular season, Seattle’s 4–2 edge over Detroit came largely thanks to their pitching depth, but the Tigers’ home record suggests this series is far from over.
With two talented starters taking the mound, Game 3 could again hinge on late bullpen execution.
Tigers Stats
The Tigers continue to grind out offense behind a team batting average of .247 (9th) and an on-base percentage of .316 (10th). They’ve hit 198 home runs (10th) but rank just 25th in stolen bases, relying more on power than speed.
On the mound, Detroit sports a 3.97 ERA (16th) with opponents hitting just .240 against them (10th). Their 52 quality starts rank mid-pack (14th), though the bullpen has proven steady in late innings.
Spencer Torkelson remains the engine, hitting .240 with 31 home runs. Gleyber Torres and Zach McKinstry add steady contact and plate discipline.
Detroit’s offense has been streaky, but when their middle order connects, they’re a tough out.

Mariners Stats
Seattle’s attack is fueled by power — their 238 home runs rank 3rd in MLB. They hit .244 as a team (11th) with a .319 OBP (7th). When their big bats are hot, runs come in bunches.
Their pitching continues to be the backbone, holding a 3.87 ERA (12th) and limiting opponents to a .240 average (10th). With 67 quality starts (6th), the Mariners consistently get length from their rotation.
Cal Raleigh’s monster 60-HR season has been the story, while Eugenio Suárez (49 HR, 118 RBI) and Josh Naylor (.295 AVG, 92 RBI) round out one of the league’s most dangerous middle orders.
However, Naylor’s paternity leave could force lineup adjustments for Game 3.

Mariners vs. Tigers Pitching Matchup
Logan Gilbert takes the ball for Seattle with a 3.44 ERA, 1.03 WHIP, and 6–6 record. His strikeout command has been sharp, and his ability to work deep into games keeps pressure off the bullpen. If he gets ahead early, he’s capable of silencing this Detroit lineup.
Jack Flaherty counters for Detroit with an 8–15 record and 4.64 ERA. His 1.28 WHIP shows occasional command lapses, but his veteran presence and swing-and-miss stuff make him a wild card.
When his slider is working, he can still dominate.
Both pitchers bring contrasting styles — Gilbert’s precision vs. Flaherty’s power — setting up another tight duel.
Seattle Mariners vs. Detroit Tigers bottom line: Given how close this series has been, the margin for error remains razor thin.
- The Tigers have gone 3-2 straight-up in their last 5 games.
- The Tigers have hit the under in 4 of their last 5 games.
- The Mariners have a straight-up record of 1-4 in their last 5 games.
- Also, the Mariners have hit the under in 3 of their last 5 games.

ALDS – Game 3 Mariners vs Tigers Prediction: Tigers ML +112
Here is my Mariners Tigers free pick. The Tigers enter this matchup playing steady baseball, going 3-2 in their last five while covering the run line in three of those contests.
That consistency, paired with the energy of playing at home, gives them a slight but meaningful edge heading into this one.
Conversely, the Mariners have stumbled down the stretch, losing four of their last five and struggling to generate offense on the road. Their 39-42 regular-season road record highlights how different this team looks away from Seattle, and that could loom large here.
With both teams trending toward low-scoring games, execution and small-ball play will likely decide it.
Detroit’s recent ability to stay composed in close contests and take advantage of scoring chances makes them dangerous in this spot. The Mariners’ lineup simply hasn’t shown enough consistency to inspire confidence against a team feeding off home-field momentum.
Considering the price and recent form, the Tigers moneyline at +112 offers solid value. My forecast says to we’ll see Detroit’s steady pitching and timely hitting carrying them to another key playoff win.
