Pittsburgh Pirates at Kansas City Royals: Final Score & Recap

The Pittsburgh Pirates defeated the Kansas City Royals 4-1 at Kauffman Stadium on August 30, 2023, in a game that was never particularly close despite the modest margin. The DiamondIQ model opened with Kansas City holding a 38% chance of winning at home, but that figure eroded steadily before reaching 0% by the final out. Pittsburgh scored in each of the first two innings, building a two-run lead that Kansas City would only partially answer in the fourth when Bobby Witt Jr. launched a home run off Andre Jackson, a swing that added 10.0% to the Royals' win probability and briefly suggested a potential comeback. That momentum, however, was quickly neutralized by Kansas City's own baserunning and contact woes, as the Royals grounded into three double plays across the fifth, seventh, and eighth innings that collectively drained 23.4 percentage points from their win-probability total.

The decisive blow came in the seventh inning when Jack Suwinski connected for a home run off Collin Snider, a swing that shifted the win probability 10.7 percentage points in Pittsburgh's favor and effectively closed the door on Kansas City's chances. Suwinski finished as the game's top batter by WPA at plus-13.8% with a RE24 of plus-1.9, while Nelson Velázquez contributed plus-8.0% WPA and Maikel Garcia added plus-7.0% WPA with a RE24 of plus-0.8. On the mound, Andre Jackson was the standout performer despite surrendering the Witt home run, finishing with a remarkable plus-19.7% WPA to lead all pitchers. Thomas Hatch added plus-6.3% WPA with a strong seventh inning, and Angel Zerpa contributed plus-5.5% WPA in relief for Pittsburgh. Kansas City finished with a error and four hits, never stringing together enough to threaten the Pirates' advantage in any meaningful way.
