Cincinnati Reds at Arizona Diamondbacks: Final Score & Recap

The Arizona Diamondbacks handed the Cincinnati Reds a lopsided 9-0 defeat on August 21, 2026, at Chase Field, turning what the DiamondIQ model opened as a 59 percent home win probability into a near-certainty by the second inning. Arizona did the bulk of its damage early, scoring three runs in the bottom of the second and adding single runs in the first, third, and seventh before tacking on two more in the eighth. Cincinnati managed just four hits and never threatened against Arizona's pitching staff, which combined to hold the Reds scoreless across nine innings.

The decisive moment came in the bottom of the second when Jordan Lawlar deposited a Nick Lodolo offering for a home run, a swing worth a 10.1 percent win-probability shift in Arizona's favor. That blow, combined with Ildemaro Vargas's sacrifice fly in the same frame adding another 2.6 percent, effectively buried the Reds before they could find their footing. Lodolo continued to struggle through the inning, and a Geraldo Perdomo strikeout ended a bases-loaded threat for Cincinnati worth 5.3 percent in Arizona's direction. Ryan Waldschmidt then extended the damage in the third with a double off Lodolo valued at 4.4 percent.

On the individual ledger, Lawlar finished as the game's most impactful offensive performer with a total WPA of plus-10.5 percent and an RE24 of plus-2.0, while Perdomo contributed plus-5.8 percent and Waldschmidt added plus-4.0 percent. On the mound, Eduardo Rodriguez was the standout, posting a WPA of plus-10.8 percent as he suppressed Cincinnati throughout his outing. The DiamondIQ model's estimate reached 100 percent by game's end, a fitting reflection of how thoroughly Arizona controlled every phase of this contest.
