Italy handed the Chicago Cubs a 9-4 defeat at Sloan Park on March 3, 2026, completing a comeback that the DiamondIQ model's estimate reflected starkly — Chicago entered with a 54% pre-game win probability that fell to 0% by the final out. The Cubs showed early signs of life in the bottom of the fourth, when Nico Hoerner's single off Javier Fandiño delivered a +15.5% swing in win probability, giving Chicago a 3-0 lead through five innings. That momentum, however, dissolved entirely in the top of the sixth.
The decisive sequence arrived when Italy erupted for four runs in the sixth against Jack Neely. Kyle Teel's home run off Neely represented the single largest win-probability swing of the game at +23.6%, effectively turning the contest on its head, and Owen Ayers followed with another home run off the same pitcher for an additional +12.7% swing. Italy then extended its lead with Thomas Saggese's solo home run in the seventh off Jeff Brigham, a +15.6% shift that pushed the Cubs further from any realistic path back. Ayers added to his damage with a run-producing single off Ben Heller in the eighth, capping a dominant offensive effort.
On the individual leaderboard, Ayers finished as the game's top performer by WPA at +21.4% with a +2.4 RE24, contributing in multiple critical moments. Teel followed at +19.5% WPA, while Hoerner's early impact registered at +18.3% despite ending up on the losing side. On the mound, Italy's Joe La Sorsa led all pitchers with +9.7% WPA, supported by Cubs starters Cade Horton and Ron Marinaccio, who each contributed positively before the sixth-inning damage was done. The model leans toward Italy's multi-inning surge in the sixth through eighth as the structural explanation for the final margin.
