The Story
The Colorado Rockies defeated the Seattle Mariners 5-3 at Coors Field on September 19, 2026, erasing an early Seattle advantage through a decisive four-run seventh inning that swung the DiamondIQ model's estimate of a Colorado win from a pre-game 44 percent all the way to a final 100 percent. Seattle had struck first with a two-run first inning and added another run in the third on a Randy Arozarena home run off Jose Quintana, a swing that shifted win probability 9.0 percent in Seattle's favor and gave the Mariners a lead they would carry into the late innings. The Mariners' three errors contributed to their undoing, and opportunities were further squandered when a Michael Arroyo double play in the top of the sixth cost Seattle 9.4 percentage points of win probability off Nick Frasso.
The seventh inning was where the game was decided. Colorado sent 10 batters to the plate against Seattle relievers Cooper Criswell and José A. Ferrer, producing four runs that turned a deficit into a lead that never changed hands. The single swing of the night belonged to Cole Carrigg, whose single off Criswell in the bottom of the seventh shifted win probability 26.5 percent toward Colorado and proved to be the most impactful play of the entire game. TJ Rumfield followed with a single off Ferrer that added another 10.9 percent to Colorado's chances, pushing the Rockies firmly in control. Carrigg finished as the game's top offensive performer by WPA at plus 20.4 percent with a RE24 of plus 1.1, while Rumfield posted plus 13.3 percent WPA. Jake McCarthy also contributed meaningfully at plus 9.2 percent WPA.
On the pitching side, Bryce Miller led all pitchers with plus 17.8 percent WPA, and Juan Mejia added plus 12.3 percent in support. Nick Frasso contributed plus 8.6 percent WPA despite allowing the Arozarena home run, as his overall work kept Seattle in check through critical stretches. Seattle finished with eight hits and three errors against Colorado's clean nine-hit, zero-error performance, a disparity in execution that the final score accurately reflected.
