The crosstown rivalry between the Chicago Cubs and White Sox delivered pure drama on Sunday, May 17, 2026, culminating in a walk-off victory for the South Siders. What started as a promising afternoon for the Cubs at Rate Field quickly unraveled, with the White Sox snatching a hard-fought 9-8 win in ten innings, securing the rubber match of their first three-game series of the season.
Under warm and windy conditions, the game saw both Chicago teams experience wild shifts in momentum. The thrilling conclusion, played out in front of a sellout crowd of 38,608, pushed the White Sox to an 80-79 lead in the all-time interleague series between the two clubs.
The Cubs initially seized control, scoring three runs in the very first inning. Nico Hoerner kicked off the offense with a leadoff single, setting the stage for Michael Busch to launch his fourth home run of the season, a 379-foot shot to right field. That blast extended Busch's career-high on-base streak to 18 games. Later, Alex Bregman singled home Dansby Swanson, further solidifying the Cubs' advantage to 4-1 by the fourth inning. White Sox starting pitcher Erick Fedde reportedly struggled early, throwing 84 pitches through just three frames.
However, the White Sox began to chip away at the lead. Andrew Benintendi responded with an RBI double in the bottom of the fourth. The momentum shifted even more dramatically in the fifth inning, when with two outs and runners on the corners, Miguel Vargas hit a drive to right-center field. Cubs center fielder Pete Crow-Armstrong attempted a leaping catch, but the ball ricocheted off the wall, resulting in a crucial two-run double that tied the game.
The score remained knotted until the eighth inning when the White Sox appeared to take firm control, building a 7-4 lead. Tristan Peters delivered his first career home run, a three-run shot off Cubs reliever Phil Maton. Speaking on the monumental moment, Peters commented, "Couldn't ask for a better moment. Probably the most emotion I've ever showed on a field, and what a series to do it in too. It was amazing." But the Cubs were not out of it yet.
In the top of the ninth, Michael Conforto hit a crucial three-run drive off White Sox reliever Seranthony Domínguez, tying the game at 7-7. This marked Domínguez's third blown save of the season and came after an error by Miguel Vargas had set the stage for Conforto's heroics, sending the game into extra innings.
The Cubs quickly regained the lead in the top of the tenth. Alex Bregman hit a slow chopper that allowed the designated extra runner, Chase Meidroth, to score off White Sox reliever Tyler Davis, making it 8-7. But the White Sox had one last comeback left in them. In the bottom of the tenth, with Chase Meidroth on third and one out, Edgar Quero stepped up to the plate. Quero, who had been struggling with a .163 slugging percentage and only four hits in his previous 37 at-bats, delivered a two-run, game-ending home run off Cubs reliever Ryan Rolison, securing the 9-8 victory for the White Sox.
Quero's walk-off blast was his first homer of the year, capping a performance where he finished with three hits and three RBIs. Reflecting on the dramatic hit, Quero remarked that it was "pretty close to my MLB debut," adding, "Hopefully I hit another one in the World Series like that, Game 7 to win the ballgame. That's it." White Sox manager Will Venable expressed confidence in his player, stating, "I'm sure it's built up in there, I know he's very excited about that one. We believe in Edgar and he's working so hard to get himself back on track and obviously that's a good sign right there."
Despite their impressive 29-17 record and leading the NL Central, the Cubs' bullpen inconsistency was highlighted by blowing a three-run lead in the eighth and then surrendering the game in the tenth. For the White Sox, now 23-22, this resilient comeback win provided significant momentum, concluding an impressive 7-2 homestand. The series itself was a high-scoring affair, with the Cubs winning the first game 10-5 on Friday night and the White Sox taking the second 8-3 on Saturday evening. The dramatic finale underscored the enduring intensity of this fierce crosstown rivalry, leaving fans on both sides eagerly anticipating their next matchup.
