Colorado Rockies at Arizona Diamondbacks: Final Score & Recap

The Colorado Rockies knocked off the Arizona Diamondbacks 3-2 at Chase Field on September 5, 2023, handing the home side a loss despite entering the game as heavy favorites. The DiamondIQ model's estimate gave Arizona a 68 percent pre-game win probability, yet the Rockies built their lead early and held it through nine innings, finishing with a clean 7-hit, 0-error performance against the Diamondbacks' 6-hit, 1-error night.

The decisive moments came in the middle innings and were sealed emphatically at the end. A Nolan Jones walk off Brandon Pfaadt in the third shifted win probability by 9.7 percent in Colorado's favor, and Brenton Doyle followed that thread with a triple off Pfaadt in the fourth worth another 9.1 percent swing. Lourdes Gurriel Jr. answered for Arizona with a double off Kyle Freeland in the bottom of the fourth that moved the needle 9.9 percent toward the home team, but the Rockies' lead proved durable. Arizona's best threats in the late innings came to nothing, most painfully when Evan Longoria struck out against Jake Bird in the bottom of the eighth, a play that swung win probability 12.9 percent against the Diamondbacks. The game's single largest win-probability event came in the ninth, when Alek Thomas popped out against Tyler Kinley, a 31.6 percent swing that formally closed the door on an Arizona comeback.

On the pitching side, Freeland and Bird were the primary architects of the Rockies' hold, contributing 26.2 and 23.3 percent in WPA respectively, with Andrew Saalfrank adding 11.1 percent in support. Among position players, Thomas led all batters with a 31.6 percent WPA figure despite a negative RE24, a reflection of how heavily his final out loomed in win-probability terms for the home side. Doyle's 0.7 RE24 made him the most efficient run-context contributor in the box score, and Brendan Rodgers chipped in 7.1 percent WPA to round out a balanced Colorado offensive effort.
