Bryan Woo Burns Through Baltimore Lineup, Mariners Win Series

The Mariners scored three runs in each of their games against the Baltimore Orioles as they began a two-series homestand against a pair of East Coast teams, a tally of runs that is seldom enough for consistent victory. And yet thanks to some incredible pitching - from Logan Gilbert on Tuesday and from Bryan Woo on Thursday - they won two of their three games and took their first series against the Orioles since 2022.

Seattle is now two games above .500, 39-37, after playing a series without Randy Arozarena or Luke Raley and having missed Josh Naylor for two games and Julio Rodríguez for one. In spite of all their hardships over the past couple of weeks, they have kept their heads barely above water as the days of June tick forward and the halfway point inches closer. 

Bryan Woo struck back on Thursday, pitching seven scoreless innings with nine strikeouts.

This year, Woo hasn’t benefited from the incredible consistency of his 2025 campaign, coming into the game with a 4.28 ERA thanks to a newfound tendency to give up scores of hits with runners in scoring position. With a 1.037 WHIP, 3.25 FIP, and 5.27 strikeout-to-walk ratio, this ERA pace marks a significant outlier. Still, it takes a certain amount of mental fortitude to keep tough innings from becoming disasters, and Woo had given up five or more earned runs in a start four times out of his most recent nine outings. Interspersed among those games were four quality starts and one “Felix quality start” of seven innings, no earned runs, and nine strikeouts.

That seven-inning outing was repeated in style on Thursday as Woo did all three of those things once more. His ERA dipped back down to 3.94 as he mowed down the Orioles inning after inning, catching them off-guard with fastballs well above the zone and using an effective two-strike mix of heaters and breaking balls. A greater unpredictability in his pitch mix was the thing Woo cited as his main adjustment.
