Colorado Rockies at Washington Nationals: Final Score & Recap

The Colorado Rockies dismantled the Washington Nationals 13-1 at Nationals Park on August 26, 2026, erasing what the DiamondIQ model had estimated as a 61 percent pre-game home win probability down to zero by the final out. Colorado's offense broke through decisively in the fifth inning, where Troy Johnston and Cole Carrigg each launched home runs off Will Dion, swinging win probability by 19.7 and 18.9 percentage points respectively. The Rockies added four more runs in the seventh and five in the eighth, putting the game well beyond reach before the Nationals could mount any meaningful response. Washington's lone highlight came in the second inning when Andrés Chaparro connected for a home run off Tanner Gordon, a swing worth 7.4 percentage points that briefly kept hope alive before Colorado's bats made it irrelevant.

Johnston led all position players with a 19.7 percent WPA and a RE24 of plus-1.9, while Connor Norby was the most impactful run-producer of the evening, finishing with a plus-4.0 RE24 and an 11.3 percent WPA anchored by his seventh-inning home run off Luis Perales. Carrigg contributed a 14.3 percent WPA despite a modest 0.2 RE24, reflecting the timing value of his fifth-inning blast. On the pitching side, Tanner Gordon led all hurlers with a plus-20.5 percent WPA for the Rockies, suppressing the Nationals offense across his outing and allowing the Colorado lineup to turn a competitive game into a rout. Colorado's 15 hits against zero errors underscored a clean, dominant performance on both sides of the ball.
