Arizona Diamondbacks at Chicago Cubs: Final Score & Recap

The Chicago Cubs defeated the Arizona Diamondbacks 2-0 at Wrigley Field on May 2, 2026, in a tight, low-scoring affair that the DiamondIQ model's estimate had favoring Chicago at 67% before first pitch and climbing to 100% by game's end. The Cubs generated their offense in just two innings, plating a run in the second and another in the eighth, while Arizona managed only four hits and never pushed a run across against a Cubs pitching staff that dominated from start to finish.

Ian Happ was the offensive catalyst for Chicago, accounting for the game's two most impactful plays by win probability. His second-inning home run off Ryne Nelson added 7.4 percentage points to the Cubs' win probability, and his eighth-inning triple off Juan Morillo proved to be the single biggest swing of the night at plus 8.8 points, helping Chicago salt away what had remained a one-run game into the late innings. Michael Busch contributed as well, delivering a third-inning double off Nelson that added 8.6 percentage points and kept pressure on Arizona's starter. On the Arizona side, Lourdes Gurriel Jr. posted a sixth-inning double off Shota Imanaga in the seventh that added 6.9 percentage points for the D-backs, though the team could not convert the opportunity, and a James McCann groundout in the same frame represented a 7.7-point swing in Chicago's favor.

Shota Imanaga was the standout performer of the game by the DiamondIQ model's accounting, posting a plus-29.7 percent win probability added to lead all pitchers. Ryne Nelson, despite surrendering both Cubs runs, still finished at plus-18.6 percent WPA, reflecting how well he kept Arizona in a game where their offense never found traction. Ben Brown added plus-17.1 percent WPA in relief to close out the shutout. Happ led all batters at plus-22.0 WPA and a RE24 of plus-2.3, making him the clear individual standout on a night that belonged entirely to Chicago.
