San Francisco Giants at Cleveland Guardians: Final Score & Recap

The Cleveland Guardians handed the San Francisco Giants a decisive 8-1 defeat at Progressive Field on August 18, 2026, a result the DiamondIQ model's estimate reflected throughout, opening with a 62% pre-game home win probability that climbed to 100% by the final out. Cleveland built its advantage early, plating three runs in the first inning and two more in the second, effectively controlling the tenor of the game before San Francisco could generate any meaningful response. The Giants finished with seven hits but were undermined by two errors and an inability to convert opportunities, ending the night well outpaced by Cleveland's 12-hit attack.

The game's most consequential sequence came in the top of the fourth inning, where a Drew Gilbert walk opened the door with a 6.3% win-probability swing in San Francisco's favor, only for Andrew Knizner to ground into a double play off Foster Griffin that collapsed that opportunity entirely, swinging win probability 12.7% against the Giants in a single at-bat. The damage in the second inning had already been done by that point, as Jo Adell delivered a home run off Carson Whisenhunt in the first inning worth 4.9% in win probability before following that with a single in the second that added another 9.2%, the latter becoming the single biggest positive swing for Cleveland across the night.

Jo Adell was the clear standout by the DiamondIQ model's metrics, finishing with a game-high plus-18.5% WPA and plus-4.9 RE24, driving the Guardians' early offensive surge that proved insurmountable. Bryce Eldridge contributed a plus-8.7% WPA showing, while Angel Martínez added plus-6.2% WPA despite his second-inning flyout registering as a momentum-shifting moment for Cleveland at plus-5.4% on the play. On the mound, Foster Griffin led all pitchers with a plus-9.2% WPA, suppressing San Francisco's best threat in the fourth and preserving Cleveland's comfortable cushion through his appearance.
