Cleveland Guardians at Chicago White Sox: Final Score & Recap

The Chicago White Sox defeated the Cleveland Guardians 5-3 at Rate Field on August 9, 2026, with the DiamondIQ model's estimate moving from a 57% pre-game home win probability to a virtual certainty by game's end. Cleveland struck first with two runs in the top of the first, and Chicago answered with one, but the game's decisive sequence came in the bottom of the third inning when the White Sox erupted for four runs against Craig Yoho to seize control. Colson Montgomery's home run was the centerpiece of that rally, adding 28.6% to Chicago's win probability in a single swing, and Randal Grichuk followed with a double that pushed the needle another 9.8%. Those two plays in the third effectively settled the outcome, with Cleveland managing only a single José Ramírez sac fly in the ninth that cost the Guardians 6.6% in win probability rather than sparking any meaningful comeback.

Montgomery was the clear standout performer, finishing with a cumulative WPA of plus 23.6% and an RE24 of plus 2.4, numbers that reflected how thoroughly his third-inning blast reshaped the game's context. Randal Grichuk contributed a plus 7.9% WPA line, while Travis Bazzana added plus 5.9% despite a slightly negative RE24 of minus 0.3. On the pitching side, Tim Herrin was the model's top-rated arm, posting a plus 12.7% WPA that was anchored in part by a Luisangel Acuña strikeout double play in the second inning, a play that cost Cleveland 8.5% in win probability. Huascar Brazobán and Sean Newcomb each contributed meaningfully as well, adding plus 7.3% and plus 7.0% respectively as Chicago's bullpen protected the lead through the final six innings of a game that was, by the model's accounting, effectively over before the fourth inning began.
