Mariners vs. Rays – Game Betting Preview & Prediction
Moneyline: Seattle -114
Spread: Seattle -1.5 (+145)
Total: 7.5
Tampa Bay Rays Betting Outlook
The Rays opened this homestand with authority, hammering Seattle 10-2 behind Shane Baz and a relentless 13-hit effort. That win tightened the wild-card race, trimming the gap to 4.5 games behind the Mariners with two other teams in between.
Tampa Bay turns to Drew Rasmussen (10-5, 2.64 ERA), who has been rock solid all season and particularly sharp in August, where he posted a 1.53 ERA with just three walks in nearly 30 innings. Rasmussen also has dominated his hometown Mariners, holding a 0.44 ERA across five career outings. He blanked Seattle for six frames earlier this month before taking a no-decision.
Offensively, Tampa Bay showed the kind of lineup depth that can break games open. However, they’ve also dealt with roster turnover after losing Ha-Seong Kim on waivers, shifting focus toward younger players like Carson Williams down the stretch. Bettors should expect a competitive Rays lineup built around contact and opportunistic hitting.
Seattle Mariners Betting Outlook
Seattle comes in as the narrow favorite at -114 on the moneyline, despite Monday’s lopsided loss. The Mariners still hold a better overall record, and their postseason push leans heavily on the consistency of Bryan Woo (12-7, 2.95 ERA).
Woo has been a workhorse all season, throwing at least six innings in 25 of his 27 starts. His August was elite, going 4-1 with a 2.27 ERA while piling up 39 strikeouts and keeping baserunners to a minimum with a 0.88 WHIP. He already has one win over Tampa Bay this season and owns a 1-0 mark with a 4.00 ERA in two career meetings.
Seattle’s offense is built around power threats who can shift momentum in a hurry, but their inconsistency at the plate has left the door open in the standings. With Woo on the hill, though, the Mariners remain a tough fade.
Prediction and Betting Angle
This game sets up as one of the better pitching duels of the week, with two right-handers carrying sub-3.00 ERAs. Rasmussen’s dominance against his hometown team gives Tampa Bay confidence, but Woo’s steady season makes Seattle the more trustworthy side with playoff urgency on their shoulders.
Score Prediction: Mariners 4, Rays 3
Pick: Seattle (-114)
