Bryan Woo delivered one of the finest outings of his season on Sunday, September 6, 2026, holding the Athletics to a single hit over eight dominant innings as the Seattle Mariners blanked Oakland 2-0 at T-Mobile Park. Woo struck out nine batters, walked two, and did not allow an earned run, giving Seattle a clean divisional victory that Andrés Muñoz locked down with a perfect ninth. In a game decided by two runs and a pitching performance that left little drama, the Mariners made a clean statement against a division rival.

Bryan Woo's Eight-Inning Shutout Performance Carries Seattle

Woo was in command from the first pitch. Over eight innings of work, he surrendered just one hit, issued two walks, and punched out nine Athletics hitters. That combination — deep into the game, minimal baserunners, consistent strikeout production — defined what the Mariners got from their right-hander on this Sunday night.

The Athletics managed almost nothing offensively against him. Gage Jump absorbed the loss for Oakland after allowing two earned runs on six hits over four innings, while striking out seven Mariners hitters. Despite the strikeout total, the damage was done early enough that Seattle's 2-0 lead held without drama.

Mariners Offense Does Just Enough Against Athletics Pitching

Seattle's offense was efficient if not explosive. Randy Arozarena led the way at the plate, going 2-for-4 to pace the Mariners' attack against Oakland's pitching staff. The two runs Woo was handed proved to be more than enough given what he was doing on the mound.

After Jump exited, the Athletics bullpen held Seattle scoreless. Seth Johnson struck out four over two scoreless innings, Scott Blewett added a strikeout in one clean inning, and Yunior Tur worked the final frame. The Mariners finished with six hits against Jump before the Oakland bullpen clamped down — but the two runs they scratched out in the first four innings were all they needed.

Andrés Muñoz Closes Out the Shutout in the Ninth

Muñoz handled the ninth inning without incident, striking out one and allowing no hits or walks to preserve the shutout and earn the save. It was a clean, professional finish to a game that Woo had already put away.
