Player Prop to Watch
Gunnar Henderson (Orioles) – Total Bases: 1.5
Henderson has recorded multiple hits in 5 of his last 7 games and continues to be a force at the top of Baltimore’s lineup. The over on 1.5 total bases offers great value in a favorable matchup.
Julio Rodríguez (Mariners) – Hits + Runs + RBIs: 2.5
Rodríguez has been streaky but is coming off a 3-for-4 night with a homer. If he stays hot, he could cash the over here with ease.
Prediction & Best Bets
Spread: Orioles -1.5 → With Rodriguez on the mound and Henderson leading the way, Baltimore should cover at home.
Total: Under 8.5 → Two elite starters on the mound could make for a low-scoring battle.
Player Prop: Gunnar Henderson Over 1.5 Total Bases → Ride the MVP candidate in his home park.
This one should be a pitcher’s duel early, but the Orioles have the bullpen and the offensive edge to pull away late. The Mariners will need a big night from Julio Rodríguez and clutch hitting from their bottom half to stay in this one. Look for the Orioles to take game one of the series in a tightly contested battle.
Final Score Prediction: Orioles 4, Mariners 2
