The Chicago Cubs escaped Petco Park with a 5-4 victory over the San Diego Padres on April 29, 2026, overcoming a DiamondIQ model pre-game home win probability of 56% in favor of San Diego. The Cubs built their lead incrementally, scoring in the second, fourth, sixth, and eighth innings, while the Padres answered with a three-run fifth and a run in the eighth to keep the game within reach. Ultimately, Chicago held on as its pitching staff navigated a tense final frame to seal the road win.
The game's most consequential sequence came in the bottom of the ninth, where Hoby Milner induced a strikeout of Ramón Laureano to close out the game, a play that registered a +31.6% swing in win probability for the Cubs. That moment represented the single largest WPA event of the night, reflecting just how close San Diego came to a potential rally. Earlier, the Padres had been dealt a critical blow in the bottom of the eighth when Manny Machado grounded into a double play off Ben Brown, a -24.2% swing that effectively deflated a San Diego threat. On the offensive side, Nick Castellanos delivered the biggest hit of the game, a home run off Jameson Taillon in the fifth inning that produced a +24.1% win-probability swing. Pete Crow-Armstrong added a fourth-inning home run off Matt Waldron worth +19.6%, and Matt Shaw's eighth-inning shot off Jason Adam at +16.7% proved to be the decisive insurance run.
Ben Brown was the clear standout of the night by the DiamondIQ model's estimate, accumulating +53.1% WPA on the mound to pace all pitchers. Laureano and Castellanos led position players with +31.6% and +31.3% WPA respectively, though Castellanos also posted a +2.1 RE24 to reflect his broader run-environment contribution. Shaw added +28.2% WPA alongside a +1.8 RE24. Bradgley Rodriguez contributed +11.5% WPA in relief support, and Taillon, despite surrendering Castellanos's home run, still finished at +9.2% WPA for his overall outing.
