Game date: September 12, 2026

By SportsJaw Editorial Team

Seattle Mariners at Oakland Athletics

Game outlook

The current spread lists Seattle Mariners at -1.5 (-109) and Oakland Athletics at +1.5 (-110). These are market lines, not a SportsJaw recommendation.

The total is 9.5 (-110) for the over and 9.5 (-110) for the under. A total pick concerns the teams’ combined score, independently of which team wins.

Opening vs current

SEA: opening spread -1.5 (-109); current spread -1.5 (-109). OAK: opening spread +1.5 (-110); current spread +1.5 (-110).

Opening over: 9.5 (-110). Current over: 9.5 (-110). Line changes alone do not establish an injury, lineup change, or betting advantage.

Moneyline

Seattle Mariners: -175. Oakland Athletics: +148. Moneyline picks concern the outright winner rather than the winning margin.
