Josh Naylor delivered a bases-clearing two-out double in the eighth, flipping a 3-1 Seattle deficit into a 4-3 lead as the Mariners clinched a playoff berth. Seattle rode a late rally, backed by solid bullpen work and a dominant home run from Dominic Canzone earlier, to extend its hot stretch to 15 wins in 16 games and tighten the hunt for the AL West crown. Colorado’s McCade Brown fanned a season-best 10, but the late Seattle surge sealed the win and kept the Mariners rolling toward postseason play.

The win sets up a pivotal next step as Seattle ponders the division title with Castillo on the mound in the upcoming clash, while Colorado looks to build on right-hander Tanner Gordon’s steady outing. The tone of the night underscored Seattle’s resilience and opportunity as the season winds down.
