Pittsburgh Pirates at St. Louis Cardinals: Final Score & Recap

The St. Louis Cardinals defeated the Pittsburgh Pirates 4-1 at Busch Stadium on August 28, 2026, with the DiamondIQ model's estimate moving from a 56 percent pre-game home win probability all the way to 100 percent by the final out. Pittsburgh's three errors proved costly against a Cardinals offense that built its lead methodically and never surrendered it, finishing with a clean fielding performance while the Pirates committed three miscues that compounded the damage.

The decisive stretch came in the third inning, when St. Louis broke a scoreless tie against Pittsburgh starter Jared Jones. Jimmy Crooks delivered the biggest single blow of the game, a home run that shifted win probability by plus 13.3 percent in the Cardinals' favor, and Nolan Gorman followed with a double that added another 7.6 percent, effectively putting St. Louis in firm command. Jones continued to struggle in the fourth, when Joshua Báez laced a double worth plus 5.1 percent in win probability and José Fermín added a single worth plus 4.6 percent to push the lead to three runs. Báez compounded Pittsburgh's misery in the eighth when a Pirates fielding error extended the Cardinals' scoring opportunity, swinging win probability an additional 5.0 percent toward St. Louis.

On the mound, St. Louis received strong contributions across its staff, with Ryan Fernandez leading all pitchers at plus 14.6 percent WPA, followed by Quinn Mathews at plus 12.7 percent and Evan Sisk at plus 6.0 percent. At the plate, Crooks and Jared Triolo each finished at plus 8.8 percent WPA, while Báez paced the Cardinals with a plus 1.5 RE24, reflecting his sustained run-creation impact throughout the game. Pittsburgh managed six hits but could not convert, and the DiamondIQ model favors Cardinals pitching depth as the primary driver of the outcome.
