Baltimore Orioles at Seattle Mariners: Final Score & Recap

The Seattle Mariners shut out the Baltimore Orioles 3-0 on June 18, 2026, at T-Mobile Park, scoring all three of their runs in the first inning and never relinquishing the lead. The DiamondIQ model's estimate had Seattle as a 59% favorite before first pitch, and that number climbed steadily to 100% by game's end, a reflection of just how thoroughly the Mariners controlled the contest from start to finish. Baltimore managed only three hits on the night and committed one error, while Seattle's pitching staff kept the Orioles off the board across all nine innings.

The most consequential sequence of the game came in the top of the eighth inning, where Baltimore mounted its most credible threat before the Mariners' bullpen slammed the door. Colton Cowser drew a walk off Bryan Woo that represented the biggest single-play swing of the game, boosting the Orioles' win probability by 8.2 percent and putting runners on base with Seattle's lead still intact. However, Eduard Bazardo stepped in and neutralized the threat decisively, as Blaze Alexander's forceout erased 7.3 percent of Baltimore's win probability and Jackson Holliday's flyout cost the Orioles another 6.4 percent. Earlier, a Leody Taveras strikeout in the second inning off Woo had drained 6.0 percent from Baltimore's chances, though Taveras did manage a single in the eighth that added 5.1 percent before the rally stalled.

On the pitching side, Eduard Bazardo was the model's top performer, generating 17.8 percent in WPA with his shutdown work, while Bryan Woo contributed 17.0 percent in a strong outing that set the tone for most of the game. Andrés Muñoz added another 2.4 percent to close things out. Among position players, Cowser led Baltimore with a WPA of plus 7.2 despite the team's futility, while Seattle's Colt Emerson paced the Mariners with a plus 3.9 WPA and the game's best RE24 mark at plus 1.8, underscoring his role in the first-inning damage that ultimately decided the contest.
