San Diego Padres at Chicago White Sox: Final Score & Recap

The San Diego Padres closed out their road trip with a commanding 6-1 victory over the Chicago White Sox on September 30, 2023, at Guaranteed Rate Field. The DiamondIQ model's estimate gave Chicago a 41 percent chance of winning before first pitch, a figure that evaporated almost immediately as San Diego's offense and pitching combined to make the outcome feel inevitable early. The Padres plated four runs in the first inning and two more in the second, effectively ending the contest before Chicago could establish any foothold in the game.

The decisive swings in win probability came from a combination of White Sox struggles at the plate and Padres execution. Andrew Vaughn's strikeout to close the first inning shifted win probability 6.8 percent against Chicago, and Trayce Thompson's strikeout in the second inning carried a 9.3 percent swing in the same direction, both against Michael Wacha. On the San Diego side, Ji Man Choi's strikeout against Tanner Banks in the top of the second registered a 8.3 percent swing in the Padres' favor, illustrating how those plate appearances defined the game's early shape. Trent Grisham contributed a groundout in the first that added 5.4 percent to San Diego's win probability, and Juan Soto doubled in the second for a 3.2 percent swing.

Michael Wacha was the dominant individual performer, generating 25.1 percent in win probability added across his outing to lead all pitchers. Among position players, Ji Man Choi finished with a WPA of plus 8.0 and a RE24 of plus 1.3, while Trent Grisham posted a WPA of plus 6.6. Juan Soto added a WPA of plus 2.7 and a RE24 of plus 1.0 to round out the Padres' most impactful contributors. Chicago's lone run came in the eighth inning, far too late to challenge a San Diego club that had thoroughly controlled the game from the opening frame.
