The Arizona Diamondbacks erased a four-run deficit with a five-run fifth inning and held on to defeat the Philadelphia Phillies 5-4 at Citizens Bank Park on April 10, 2026. Philadelphia had scored all four of its runs in the bottom of the first, and the game stood that way through four innings before Arizona's offense erupted against Jesús Luzardo. The DiamondIQ model's estimate of a Philadelphia win sat at 54% before first pitch, and the Phillies appeared to be validating that projection through the early going, but it shifted decisively against them once Arizona's comeback took shape.
The pivotal sequence came in the top of the fifth, when James McCann delivered a two-run double off Luzardo that represented the single biggest win-probability swing of the game at plus 22.6 percent, and Ildemaro Vargas followed with a single that added another 11.4 percent. McCann finished as the game's top batter by WPA at plus 24.0 percent with an RE24 of plus 1.6, making him the clearest difference-maker offensively. Philadelphia mounted a threat in the ninth when Justin Crawford laced a triple off Paul Sewald worth plus 12.6 percent, keeping the Phillies alive momentarily, but Trea Turner's subsequent flyout flipped 19.0 percent of win probability back to Arizona, sealing the result.
On the mound, Juan Morillo was the most valuable arm in the game, posting a plus 25.4 percent WPA that included Adolis García's strikeout in the bottom of the eighth, which represented a 16.5 percent swing in Arizona's favor. Jonathan Loáisiga contributed plus 12.8 percent and Orion Kerkering added plus 7.4 percent as the D-backs bullpen protected the one-run lead through the final frames. Arizona finished with seven hits and no errors, matching Philadelphia's line across both categories, with the outcome ultimately determined by the concentration of run production in a single inning.
