The Seattle Mariners defeated the Houston Astros 6-1, preventing the Astros from clinching the AL West title in the first game of their series. Bryce Miller pitched seven shutout innings, allowing only two hits and striking out five, while Julio Rodríguez contributed three hits and two RBIs. This victory puts Seattle (81-76) just 1.5 games behind the final AL wild-card spot and four games behind the Astros (85-72) in the division. The Mariners had a strong offensive showing, scoring four runs in the final two frames to seal the win. Houston's Yordan Alvarez missed the game due to a knee injury, and despite a solid performance from Astros pitcher Hunter Brown, the team fell short. The two teams will meet again for the second game of the series, with Seattle looking to further narrow the gap.
