Kansas City Royals at Chicago White Sox: Final Score & Recap

The Kansas City Royals handed the Chicago White Sox a 7-1 defeat at Guaranteed Rate Field on September 13, 2023, overcoming a pregame environment in which the DiamondIQ model's estimate gave Chicago a 62% win probability. The Royals chipped away early and pulled away decisively late, ultimately reducing that home-side probability to zero by the final out. Kansas City finished with 10 hits to Chicago's 5, committing one error to the White Sox's none.

The game's pivotal sequence began in the second inning, when Michael Massey connected on a home run off Mike Clevinger, a swing that shifted win probability 7.7 points in Kansas City's favor. That same half-inning, a Nick Pratto strikeout with runners on added another 6.2 points for the Royals as Chicago failed to capitalize, and in the bottom half, Gavin Sheets struck out against Steven Cruz in a moment that swung probability 9.7 points away from the White Sox. Chicago's offense continued to struggle, most notably in the bottom of the fifth when Elvis Andrus grounded into a double play off Alec Marsh, a sequence that cost the home side 7.1 points of win probability. The Royals then put the game out of reach in the seventh, with Nick Loftin's single off Lane Ramsey generating an 8.4-point swing and anchoring a three-run frame.

Among individual contributors, Alec Marsh was the standout by the DiamondIQ model's accounting, accumulating 21.1 points of win probability added on the mound, while Steven Cruz added 15.7 and James McArthur contributed 5.3 in support. Offensively, Loftin led all batters with 8.9 points of WPA and a RE24 of plus-2.0, followed by Pratto at plus-8.3 WPA and Salvador Perez at plus-7.3 WPA with a RE24 of plus-1.4.
