The Cleveland Guardians held off the Kansas City Royals 6-5 at Goodyear Ballpark on March 19, 2026, in a game that required a late push to secure. The DiamondIQ model entered with a 73% pre-game estimate in favor of Cleveland and finished at 100%, though the path there was anything but clean. Cleveland built its foundation early, with Kyle Manzardo delivering a home run off Noah Cameron in the bottom of the second — a swing that added 12.8% to Cleveland's win probability and gave the Guardians a 4-1 lead through two innings. Kansas City kept chipping away, and it was Connor Scott who delivered the most impactful offensive moment of the game, connecting on a home run off Connor Brogdon in the top of the seventh for a +17.0% win probability swing that narrowed the deficit to 5-4. Peyton Wilson had also kept the Royals alive with a solo shot off Parker Messick in the fifth, adding 12.4% to Kansas City's chances.
Cleveland answered in the bottom of the eighth when Carter Kieboom singled off Helcris Olivárez, a play worth +15.5% in win probability that extended the Cleveland lead back to 6-4 and effectively put the game beyond reach. Kansas City mounted a ninth-inning threat, but Ramon Ramirez's lineout against Izaak Martinez cost the Royals 10.9% in win probability and closed the door. By the final numbers, Scott led all batters with a +20.8% WPA and +1.1 RE24, while Wilson finished at +17.6% WPA and +1.2 RE24 despite being on the losing side. On the mound, Izaak Martinez paced Cleveland's pitching staff with a +15.2% WPA contribution, followed by Tim Herrin at +10.6% and Steven Cruz at +10.0%, as the Guardians converted a position of early strength into a narrow but complete victory.
