The Story

The Chicago White Sox defeated the Chicago Cubs 9-8 in ten innings on May 17, 2026, at Rate Field, completing a dramatic comeback that saw the DiamondIQ model's estimate of a home win climb from 44% before first pitch all the way to 100% by game's end. The White Sox trailed heading into the eighth inning before a three-run frame shifted the momentum, and the two clubs traded blows across the final three innings in one of the wilder editions of the crosstown rivalry.

The decisive sequence began in the bottom of the eighth, where Tristan Peters delivered a home run off Phil Maton that swung win probability 39.6 points toward Chicago's South Siders. The Cubs answered in the top of the ninth when Michael Conforto hit a home run off Seranthony Dominguez, a swing worth 41.2 percentage points that knotted things back up and sent the game to extra innings. In the tenth, Dansby Swanson drew a walk off Tyler Davis that moved the DiamondIQ model's estimate 32.0 points toward the Cubs, giving Chicago a lead. The White Sox then responded with a two-run tenth of their own, capped by Edgar Quero's walk-off home run off Ryan Rolison, a blow worth 56.3 percentage points and the single biggest win-probability swing of the night.

By WPA, Edgar Quero was the game's most impactful player at plus-51.6 percentage points, with his decisive blast supported by a RE24 of plus-0.9. Andrew Benintendi finished at plus-42.0 WPA with a RE24 of plus-2.2, having contributed throughout the lineup, including a sacrifice bunt in the tenth that registered plus-23.7 points on its own. Michael Conforto led all Cubs batters at plus-42.4 WPA with a RE24 of plus-2.0, his ninth-inning shot briefly the night's most consequential swing. On the mound, Grant Taylor led White Sox relievers at plus-15.4 WPA, followed by Hoby Milner at plus-12.7 and Jacob Webb at plus-11.4.
