The Cleveland Guardians defeated the Baltimore Orioles 4-2 at Progressive Field on April 18, 2026, in a game that turned decisively on a single swing in the bottom of the fifth inning. The DiamondIQ model's estimate entered the day favoring Cleveland at 61% and closed at 100%, with the trajectory of that probability shifting most dramatically when Brayan Rocchio connected on a home run off Dean Kremer, a play worth +35.0% in win probability. That blast was the single largest swing of the contest and effectively separated a scoreless game from a Cleveland lead that Baltimore would never fully overcome. Leody Taveras had given the Orioles a 1-0 advantage with a fourth-inning home run off Gavin Williams worth +11.6%, but Rocchio's three-run shot in the fifth erased that lead and put the Guardians firmly in control.
Baltimore made a brief push in the eighth when Gunnar Henderson hit a home run off Hunter Gaddis, a swing valued at +13.7% in win probability that pulled the Orioles to within one. Cleveland responded immediately, as Bo Naylor answered with a home run of his own off Albert Suárez in the bottom half of the inning, a blow worth +12.0% that restored the two-run cushion and effectively ended Baltimore's chances. The final line read CLE 4/3/1 against BAL 2/4/0, with Cleveland's three hits proving more efficiently deployed than Baltimore's four.
Rocchio finished as the game's top performer by both WPA and RE24, posting a cumulative +33.2% and +2.4 respectively on the strength of his pivotal fifth-inning drive. Gavin Williams led all pitchers with +17.8% WPA for Cleveland, absorbing the Taveras home run while otherwise keeping Baltimore in check across his time on the mound. Henderson's +14.7% WPA and Taveras's +8.8% represented Baltimore's most impactful individual contributions, though neither was enough to overcome the decisive moment Rocchio provided.
