Tony Sartori’s Mariners vs Tigers Game 3 Predictions

Why The Mariners Can Win

Logan Gilbert has consistently been one of the best pitchers in the American League since being called up in 2021. That success has continued into this year, as he posted a 3.44 ERA and 1.03 WHIP through 25 starts.

His underlying metrics suggest that this success will continue into the postseason. In 2025, Gilbert recorded a 3.02 expected ERA (xERA) and .212 expected batting average (xBA).

He also ranked in the 94th percentile in strikeout rate and the 86th percentile in walk rate.

This success is likely to continue against Detroit, a team Gilbert has dominated. Over the past four meetings, the right-hander boasts a 2.45 ERA and 1.09 WHIP.

Why The Tigers Can Win

Meanwhile, the Tigers have struggled to produce runs this postseason. They have relied on their pitching, scoring three or fewer runs in four of their five playoff games.

That said, this reliance on pitching may hurt them in this matchup, as right-hander Jack Flaherty takes the mound. While Flaherty pitched well in his Wild Card start against Cleveland, he now faces an entirely different beast in Seattle.

During the regular season, the Mariners ranked in the top 10 in total runs, slugging percentage, OPS and home runs. At the same time, Flaherty’s analytics in 2025 were concerning.

The right-hander finished in the bottom half of the league in xERA, average exit velocity, barrel rate and hard-hit rate.


How To Make Mariners vs Tigers Picks

Not only does Seattle possess the edge in starting and relief pitching, but it also holds the hitting advantage. This season, the Mariners’ bullpen finished in the top 10 in ERA, fielding independent pitching (FIP) and expected FIP (xFIP).

On the other hand, Detroit’s bullpen ranked in the bottom half of the league in all three categories.

The only advantage the Tigers hold in this game is home-field advantage, but that’s not enough to offset all the other variables.

Pick: Mariners Moneyline (-130 | Play to -135)


Moneyline

As mentioned, I'm betting the Mariners moneyline.


Run Line/Against The Spread

I also like the Mariners to cover, but I find more value in just taking the outright moneyline price.


Over/Under

I lean toward the under, but don't trust Flaherty.
