Over/Under Prediction: Under 7.5 runs
Best Bet: Under 7.5 (-110)
This projects as a pitcher’s duel. With two young arms who throw hard and two inconsistent offenses, we’re siding with the under. Seattle’s bullpen is more trustworthy, and home field gives them a slight edge late in a low-scoring game.

- Mariners ML (-120)
- Julio Rodríguez Over 1.5 Total Bases (+100)
