The Story
The Pittsburgh Pirates handed the San Francisco Giants a 9-4 defeat at Oracle Park on May 31, 2023, a result that swung decisively and early against the home side. The DiamondIQ model opened with a 53% pre-game win probability favoring San Francisco, but by the final out that figure had collapsed to 0%, reflecting how thoroughly Pittsburgh seized control of the contest. The Pirates finished with 14 hits against 12 for the Giants, with San Francisco's two errors further compounding the damage.
The third inning was where the game effectively turned. Alex Wood absorbed the brunt of Pittsburgh's offense across the middle frames, and Ke'Bryan Hayes delivered the most consequential blow of the night, a triple that shifted win probability by 19.6 percentage points in the Pirates' favor. Rodolfo Castro followed that up with a single worth another 9.5 percentage points, as Pittsburgh pushed four runs across in the third to break the game open. The Giants offered a flicker of a response in the bottom half, but Mike Yastrzemski's strikeout against Mitch Keller erased 6.3 points of San Francisco's win probability and effectively ended any realistic path back. Bryan Reynolds then extended the damage in the fourth with a single off Wood worth 14.7 percentage points, and Pittsburgh added two more runs that inning to push the lead well beyond reach.
By cumulative WPA, Hayes finished as the night's standout offensive contributor at plus-20.1%, backed by a RE24 of plus-1.7, while Reynolds and Castro each posted WPA figures of plus-15.7% and plus-13.3% respectively, with identical RE24 marks of plus-1.4. On the pitching side, Rob Zastryzny led Pittsburgh's relief corps with a WPA of plus-2.1%, followed by Dauri Moreta at plus-1.5% and Robert Stephenson at plus-1.2%, as the bullpen closed out the final innings without incident.
