Mariners vs. Mets – Game Betting Preview & Prediction
Moneyline: NY Mets -120
Spread: Seattle -1.5 (+160)
Total: 8.5
Seattle Mariners Betting Outlook
The Mariners head into New York as slight underdogs with the total set at 8.5 runs. Their momentum hit a speed bump this week, dropping two straight to Baltimore after an impressive eight-game win streak. Even with back-to-back losses, Seattle has gone 9-3 in August, climbing to the top of the AL wild-card race and closing within 1.5 games of the Astros in the AL West.
Thursday’s 5-3 loss to the Orioles marked the first time this month they trailed wire-to-wire. They fell behind 5-0 but rallied late, highlighted by Julio Rodriguez’s two-run homer. The fight is there, they just need to avoid digging early holes. Luis Castillo (8-6, 3.19 ERA) gets the start, coming off a seven-inning, two-run outing against Tampa Bay. He’s been reliable and owns a 2-1 career record against the Mets.
New York Mets Betting Outlook
The Mets are slight -120 moneyline favorites but are spiraling hard, posting a league-worst 2-10 record this month. It’s a stunning fall from grace after holding the best record in MLB in mid-June. They still hold a narrow half-game lead for the final NL wild-card spot, but they’ve led in seven of their losses this month and have repeatedly let games slip late.
Thursday’s 4-3 loss to Atlanta was another gut punch, as New York blew two separate one-run leads. Sean Manaea (1-1, 4.33 ERA) takes the mound, looking to bounce back after giving up four runs in four-plus innings against Milwaukee. Historically, he’s been solid against Seattle, posting an 8-8 record and 3.88 ERA in 18 career appearances.
Prediction & Betting Angle
The Mariners are in better form, but the Mets’ desperation and home-field edge make this opener tricky to call. If Castillo keeps the ball in the yard, Seattle’s hot bats could tilt the balance.
Score Prediction: Mariners 5, Mets 4
Pick: Seattle (+103)
Total: Over 8.5 (-102)
