The Story
The Pittsburgh Pirates handed the San Francisco Giants a 5-2 defeat at PNC Park on September 3, 2026, a result the DiamondIQ model's estimate anticipated from the outset, with Pittsburgh entering at a 62% pre-game home win probability and closing at 100%. The Pirates struck early, plating two runs in the first inning, then added two more in the sixth before tacking on a final run in the eighth. San Francisco's only offense came in the seventh inning, and it proved too little to threaten a Pittsburgh club that controlled the contest from wire to wire. The Giants finished with just two hits and committed an error, while the Pirates posted five hits without a miscue.
The game's most consequential sequence began in the top of the fifth, when Nate Furman grounded into a double play off Khristian Curtis, a play that shifted win probability 9.5 percentage points against San Francisco and effectively extinguished a potential Giants rally. Pittsburgh responded in the bottom of the sixth when Jake Mangum laid down a sacrifice bunt off Reiver Sanmartin, a play credited with a 6.0% swing in Pittsburgh's favor that helped set the table for the Pirates' second two-run frame. The seventh inning produced the game's most active stretch, with Turner Hill drawing a walk and Jung Hoo Lee following with a double off Curtis, each move shifting probability roughly 5.5 points toward the Giants, but Christian Koss's lineout against Yohan Ramirez ended the threat with a 5.0% swing back to Pittsburgh.
On the individual ledger, Mangum led all batters with a WPA of plus-9.1% and a RE24 of plus-2.1, making him the game's most impactful offensive contributor by the DiamondIQ model's estimate. Jung Hoo Lee and Shay Whitcomb each registered plus-5.4% WPA on the San Francisco side, accounting for nearly all of the Giants' meaningful offensive moments. On the mound, Luke Weaver paced Pittsburgh's pitching staff with plus-8.1% WPA, supported by Lake Bachar at plus-6.2% and Ramirez at plus-6.0%, a collective effort that kept San Francisco's already thin offense from gaining any sustained footing.
