Skubal’s stingy arm meets Rodríguez’s roar in the Emerald City.

Detroit Tigers

Tigers (87-75) VS Mariners (90-72)

04 Oct 2025 | 8:38 PM ET | T-Mobile Park, Seattle, WA

Seattle Mariners
Moneyline Pick – Seattle Mariners (-220): Grade B

Seattle enters this matchup with momentum and strong situational advantages, including a bullpen that’s been dominant since the All-Star break and a lineup performing efficiently at home. Their substitute starter has been reliable in this park, and even with rotation shuffling due to injury, the Mariners maintain stability across the roster. Detroit’s lineup remains weakened without one of its key power bats, and the road venue has been particularly unkind to them in recent meetings. With postseason positioning still a factor, Seattle’s depth and late-inning edge give them the clear upper hand. This prediction leans on bullpen strength, matchup familiarity, and home-field consistency.

From a betting standpoint, the pick favors Seattle on the moneyline as the sharper side. The Tigers’ recent struggles in this setting and diminished offensive threat reduce upset potential, while the Mariners’ balanced structure supports the chalk. With motivation high and reliable arms available, backing the home favorite is the logical move.

Over/Under Pick – Under 7 (-115): Grade B+

Both starters enter in peak form, setting up a matchup where quality pitching should dominate the flow. Detroit’s ace has been particularly sharp on the road, while Seattle’s starter continues to excel in his home park, limiting traffic and hard contact. Each bullpen ranks among the league’s best in win probability added since September, ensuring that late innings should remain under control. With cooler October conditions at T-Mobile Park reducing carry on deep contact, the environment only strengthens the case for limited offense. This prediction leans on elite pitching metrics, bullpen reliability, and historical scoring trends.

From a betting standpoint, the pick favors the Under, as both teams possess arms capable of neutralizing big innings. Recent meetings and current form support a low total, and neither lineup projects as explosive in these conditions. Expect a tight, methodical contest likely to stay well below the posted number.

Spread Pick – Detroit Tigers +1.5 (-125): Grade B

Detroit’s strong record on the run line behind its ace reflects how often he keeps games close, even against playoff-caliber opponents. His command and strikeout mix give the Tigers a reliable anchor, and their lineup has shown enough on-base ability against Seattle’s pitching staff to stay competitive deep into games. The Mariners, meanwhile, have been involved in plenty of one-run outcomes over the back half of the season, underscoring how frequently their games come down to late leverage spots. With both bullpens ranked among the league’s best, separation may again be tough to find. This prediction leans on pitching consistency, bullpen parity, and historical closeness between these clubs.

From a betting perspective, the pick favors Detroit +1.5 as the smarter, lower-risk angle. Even with Seattle expected to edge the result, the Tigers’ ability to grind through tight contests behind elite starting pitching makes the cushion appealing. Given the frequency of one-run finishes in Seattle’s recent slate, the value lies with taking the extra run.
