Run Line -1.5 • Seattle Mariners

Play: Seattle Mariners -1.5 +105, staking 3 units. Rationale: favorable matchup dynamics (offensive depth versus the opponent's rotation and a bullpen setup that can protect leads) suggest the Mariners have the tools to create separation over nine innings; take the line as a bet on that structural advantage rather than variance. Operationally, -1.5 implies Seattle must win by at least two runs, so the projected game flow is an early or mid-game push for a multi-run lead followed by controlled bullpen work to preserve that margin.
