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

The Chicago White Sox defeated the Kansas City Royals 6-4 at Kauffman Stadium on September 6, 2023, handing the home side a loss despite the DiamondIQ model's pre-game estimate giving Kansas City a 46 percent chance of winning. The White Sox collected 14 hits against just four for the Royals, and the game turned decisively in the visitors' favor through a pair of multi-run innings. Kansas City scratched across two runs in the bottom of the fourth on a Nelson Velázquez home run off Touki Toussaint that shifted win probability by plus-22.8 percent in the Royals' direction, giving the home team a brief advantage. That lead evaporated entirely in the top of the sixth, when Andrew Vaughn connected off Jordan Lyles for a home run worth plus-22.1 percent in win probability, followed shortly by a Yoán Moncada shot off Tucker Davidson that added another plus-13.0 percent swing, turning a deficit into a three-run Chicago lead in the span of a single inning.

Kansas City mounted a challenge in the bottom of the eighth, with Edward Olivares launching a home run off Aaron Bummer that added plus-24.2 percent win probability for the Royals and pulled the game to within two runs. The threat stalled there, however, as a Freddy Fermin lineout off Gregory Santos erased 12.9 percent of Kansas City's remaining win probability and effectively sealed the outcome. Santos finished as the most valuable pitcher on the night by WPA at plus-17.1 percent, while Lane Ramsey contributed plus-6.3 percent out of the bullpen. On the offensive ledger, Vaughn led all batters with a plus-25.3 percent WPA and a RE24 of plus-2.0, while Olivares posted plus-24.2 percent WPA despite his home run coming in a losing effort. Velázquez rounded out the top-three batters by WPA at plus-12.8 percent. The DiamondIQ model closed with Kansas City's win probability at zero percent, a reflection of how thoroughly the White Sox controlled the final stages of the contest.
