Braden Montgomery’s Walk-Off Home Run Caps Historic MLB Debut for the Chicago White Sox

On June 9, 2026, at Rate Field, Chicago White Sox rookie outfielder Braden Montgomery delivered a two-run walk-off home run in the bottom of the 10th inning against the Atlanta Braves. With two outs, a runner on third and the Sox trailing 5-4, Montgomery faced Braves closer Raisel Iglesias and hit a 0-1 changeup for a 343-foot opposite-field blast that cleared the left-field wall and landed in the bullpen. The swing produced a 6-5 win and gave Montgomery a 2-for-5 line with three RBIs in his major-league debut.

Montgomery entered Chicago as the No. 2 prospect and the 21st-overall player in MLB Pipeline’s 2026 rankings. The 12th overall pick in the 2024 draft by the Boston Red Sox, he was traded to the White Sox in December 2024 for left-hander Garrett Crochet. Before his call-up, he posted a .314 average with ten homers and a .970 OPS across Double-A Birmingham and Triple-A Charlotte. After a 2025 season with 102 losses, the White Sox were 35-31 in 2026, a half-game behind the Cleveland Guardians for the AL Central lead and holding the top AL wild-card spot.

Montgomery’s walk-off homer made him the fifth player in MLB history to end a debut with a walk-off home run, joining Billy Parker (1971), Josh Bard (2002), Miguel Cabrera (2003) and Carlos Perez (2015). The Braves entered the game with the league’s best record at 45-22. Chicago’s win was its 17th one-run victory of the season and moved the team to 13-6 in its last 20 home games.

Montgomery called the moment “something out of dreams” and praised the team, staff and fans. Manager Will Venable called him a “special player” and said he will stay in the everyday lineup. Pitcher Erick Fedde praised Montgomery’s work ethic, noting few experience such a debut. The front office cited the Garrett Crochet trade as a key part of the rebuilding plan.

Venable called the team’s execution a “disaster,” citing failed bunts, three runners thrown out at home and missed safety squeezes. He took personal responsibility for the situational lapses, stressing that better execution is essential for sustained success.
