The Cleveland Guardians handed the Arizona Diamondbacks a 10-5 defeat at Chase Field on March 24, 2026, in a game that was never truly close despite what the final margin might suggest. Cleveland struck early and decisively, plating four runs in the first inning and adding two more in the third to build a 6-0 lead before Arizona mounted any meaningful response. The DiamondIQ model entered the game with a 51 percent home win probability for Arizona, but by the final out that figure had fallen to zero, reflecting how thoroughly Cleveland controlled the contest from start to finish.
The game's decisive sequences are best understood through win-probability movement. Parker Messick kept Cleveland in check through the middle innings, but the Diamondbacks were unable to capitalize on their moments against him, with Alek Thomas grounding out in the second inning at a cost of 10.9 percent win probability and Nolan Arenado lining out in the first at a 9.1 percent swing. Jordan Lawlar's single off Messick in the fourth, which carried a 16.0 percent win-probability swing in Arizona's favor, represented the Diamondbacks' best moment of the night, driving a four-run fourth that briefly made it a 6-4 game. However, Jesus Valdez's ground into a double play in the seventh off Ross Carver extinguished a potential rally at a cost of 11.6 percent win probability, and Cleveland responded with a three-run eighth that put the game away. Nolan Schubart's home run off Sandro Santana in that eighth inning was the single biggest play of the night, adding 16.6 percent win probability from Cleveland's perspective.
Schubart finished as the game's top performer by WPA at plus-19.2 percent with a RE24 of plus-3.3, while Lawlar led Arizona's batters at plus-14.9 percent WPA despite the loss. Kyle Manzardo contributed a plus-8.0 percent WPA for Cleveland, and on the mound Ross Carver and Spencer Giesting each posted plus-8.8 percent WPA to anchor a Guardians pitching staff that held Arizona to eight hits. The model leaned slightly toward Arizona before first pitch, but Cleveland's first-inning explosion made that pregame edge essentially irrelevant within the opening frame.
