Seattle Mariners vs Cincinnati Reds : Seattle Mariners -2 (+177)
Odds available at NA at time of publishing
As the Seattle Mariners gear up to host the Cincinnati Reds, there's a palpable sense of momentum with the Mariners. They’ve been on a tear at home, showcasing a lineup that has consistently found ways to score, averaging over five runs per game in their last ten outings. Their recent series against strong pitching has only sharpened their bats, making them a formidable opponent.
On the mound, the Mariners boast a pitcher with a sub-3.50 ERA who’s been particularly effective against left-handed hitters, which plays directly into the Reds’ struggles against righties. Meanwhile, Cincinnati’s rotation has shown cracks, allowing a concerning number of runs, especially in high-pressure situations.
With the Mariners looking to cement their playoff hopes, expect them to not just win, but to dominate. Taking Seattle on the alternate run line at -2 feels like a smart play; they’re ready to flex their muscles at T-Mobile Park.
Seattle Mariners vs Cincinnati Reds : Seattle Mariners -2.5 (+210)
Odds available at NA at time of publishing
As the Seattle Mariners prepare to host the Cincinnati Reds, there’s a compelling narrative unfolding that supports a bet on the Mariners -2.5 on the run line. Seattle has been a different animal at T-Mobile Park, boasting a robust home record that’s bolstered by an explosive offense. Over their last series, they've been raking, with key players stepping up and a batting average that ranks among the league's best.
On the flip side, the Reds have struggled on the road, particularly against left-handed pitchers, and with the Mariners likely sending a southpaw to the mound, we could see their lineup falter again. The Mariners’ pitching staff has also been sharp, allowing them to dominate lesser competition. Given the recent trends and the Mariners' ability to not just win but win decisively at home, taking them to cover a -2.5 run line seems like a savvy play in this matchup.
Randy Arozarena (TBR) Under 1.5 Total Bases (-164)
Odds available at draftkings at time of publishing
As the Mariners host the Reds, all eyes will be on Randy Arozarena, but taking the under on his total bases feels like a savvy play. Arozarena has been solid, but he’s facing a Mariners pitching staff that’s been stingy at home, holding opponents to a mere .215 batting average over the past month.
Moreover, Arozarena’s recent form shows he’s been more of a singles hitter lately, accumulating just a handful of doubles and no home runs in his last ten games. When you factor in that Seattle's bullpen has been lights out, particularly in high-leverage situations, it’s clear that scoring opportunities may be limited.
With the Reds’ recent slump and with Arozarena likely to face some tough matchups, betting the under on his total bases seems like the smart money here. Keep an eye on the game, but expect him to struggle to cross that 1.5 mark tonight.

Meanwhile, their pitching staff, particularly at home, has excelled, boasting a solid ERA that puts them among the league's elite.
Cincinnati, on the other hand, has struggled on the road, and their inconsistency at the plate could be a significant factor. The Mariners have not only shown the ability to score but also to shut down opponents, making them formidable at T-Mobile Park. With a recent surge that has seen them outscore rivals decisively, this matchup sets up well for Seattle to cover the spread. Expect the Mariners to seize the moment and deliver a decisive victory.
