The Cleveland Guardians shut out the Milwaukee Brewers 1-0 on March 12, 2026, at Goodyear Ballpark, with the DiamondIQ model's estimate moving from a 54 percent pre-game home win probability all the way to 100 percent by the final out. Cleveland's lone run came in the first inning and proved to be all the offense either side would generate across nine frames, as Milwaukee managed just three hits and Cleveland four against a backdrop of dominant pitching on both sides.
The win-probability swings told the story of a game decided in incremental, grinding moments rather than any single explosive play. The largest single swing belonged to Aaron Walton, whose groundout in the bottom of the eighth added 7.8 percent win probability for Cleveland, reflecting how effectively the Guardians were protecting their slim lead against a Brewers lineup that could not string anything together. Milwaukee's most threatening sequence came in the top of the seventh, where Gary Sánchez singled off Connor Brogdon to generate a 6.4 percent swing in the Brewers' favor, only for Ethan Murray to strand that momentum with a strikeout that gave back 5.8 percent. Brandon Lockridge's strikeout to open the ninth off Will Dion swung 7.1 percent back toward Cleveland and effectively sealed the outcome.
On the pitching side, Slade Cecconi led all players with a 16.6 percent WPA contribution, followed closely by Will Dion at 15.2 percent and Codi Heuer at 10.8 percent, a trio that collectively kept Milwaukee off the board through the middle and late innings. Among position players, Walton's 7.8 percent WPA topped the offensive ledger, while Jett Williams contributed a steady 3.6 percent WPA with a plus-0.5 RE24, and Sánchez added 3.4 percent despite finishing with a flat run-expectancy figure. The DiamondIQ model leans toward recognizing Cleveland's pitching staff as the central factor in determining this outcome.
