AL West Warfare: Unpacking the 2025 Season Series Trail
Under MLB's balanced schedule format, the Mariners and Astros faced off 13 times during the 2025 campaign, down from the traditional 19 games in pre-2023 seasons. This compressed schedule heightened the leverage of every single contest between Seattle and Houston.
Seattle established an early advantage during the spring series at T-Mobile Park, taking two out of three games behind stellar outings from Logan Gilbert and George Kirby. The Astros responded during the summer months at Minute Maid Park, leaning on veteran starter Framber Valdez to split a crucial four-game series in Houston.
The pivotal turning point arrived during their final September series in Seattle. The Mariners captured two of three games, officially securing the 7-6 season series victory. That tiebreaker proved crucial in late-season seeding, ensuring Seattle held the direct tiebreaker advantage over Houston for postseason berth tie-breakers.
