The Seattle Mariners took a hard-fought 3-2 decision over the Houston Astros on Sunday, August 16, in a nine-inning divisional battle that came down to the final out. Bryan Woo earned the win after delivering six innings of three-hit, two-earned-run ball with five strikeouts, and Andrés Muñoz locked it down with a dominant ninth — two strikeouts, no hits, and one walk — to collect the save. Randy Arozarena, Dominic Canzone, and Cal Raleigh each contributed offensively as Seattle grinded out just enough runs against Houston's bullpen. Every competitive rep against a division opponent counts.

Bryan Woo Controls the Game, Earns the Win

Woo was the story from the jump. The right-hander went six innings, allowing just three hits and one walk while striking out five Houston batters. He was charged with two earned runs but kept the Mariners in position to win throughout his outing. Hunter Brown started for Houston and had a rougher time of it — five innings, two earned runs, five strikeouts, but also five walks, which kept Seattle's lineup alive in key spots. Brown took the loss.

Arozarena, Raleigh, and Canzone Provide the Offense

Arozarena led the way at the plate, going 2-for-5 with a home run and an RBI. Cal Raleigh added a home run of his own, going 1-for-3 with an RBI. Dominic Canzone chipped in a 2-for-4 performance with an RBI, giving Seattle three separate contributors who each put a run on the board. That balanced attack proved to be enough.

Houston's offense was kept in check for most of the game but did get home run contributions from Jeremy Peña — 1-for-4 with a solo shot — and Nick Allen, who went 1-for-2 with a home run and an RBI. Both Astros runs came via the long ball, which speaks to how well the Mariners pitching staff limited Houston's ability to string anything together.

The Bullpen Holds It Together

After Woo exited, Seattle turned to Eduard Bazardo for a clean inning, then Gabe Speier and Seranthony Domínguez navigated a tight stretch — Speier allowed two hits across two-thirds of an inning but escaped without surrendering a run, and Domínguez struck out one in a third of an inning. Muñoz then took the ball in the ninth and was nearly untouchable: two strikeouts, no hits allowed, and one walk, the game sealed.

Houston's bullpen arms — Bennett Sousa, Bryan Abreu, Steven Okert, and Josh Hader — combined to cover the final four innings after Brown's exit. Sousa was the weak link, giving up three hits and an earned run in his lone inning, which proved to be the decisive blow for Seattle's margin.

Turning Point: Canzone's RBI Extends the Lead

With Arozarena's home run and Raleigh's homer accounting for two Seattle runs, Canzone's RBI hit off Sousa in the middle innings extended the lead to 3-1 and gave the Mariners the cushion they needed. That third run proved essential once Houston's bats responded with a solo shot to cut the gap to 3-2. Seattle never gave the lead back.

What's Next

  • The Mariners will look to build on this divisional win as they continue preparing for the 2026 regular season.
  • Bryan Woo's performance reinforces his role at the front of Seattle's rotation — six innings, five strikeouts, and command of a division opponent is exactly what the coaching staff wants to see.
  • Muñoz's ninth is a strong indicator of where he stands as Seattle's late-inning option, striking out two and allowing no hits to close it out.
  • Keep an eye on Arozarena and Canzone — both went 2-for-4 or better and factored directly into the winning margin.
