Braden Montgomery hit a walk-off home run in the 10th inning of his major league debut on June 9, 2026 [1], [2].
The home run secured a 6-5 win for the Chicago White Sox against the Atlanta Braves [3]. The performance is significant because Montgomery is now only the fifth player in MLB history to hit a walk-off home run during his debut [4].
Montgomery entered the game after being called up as the No. 2 prospect for the White Sox [5]. His first at-bat resulted in the game-ending blast in Chicago [2], [6]. The victory keeps the White Sox within reach of the division lead, leaving them half-game behind the Cleveland Guardians in the AL Central [7].
The prospect has previously expressed high ambitions for his professional career. "My overall goal is to make the Hall of Fame," Montgomery said in a previous interview with the Sun-Times [8].
The 10th-inning victory was highlighted by a call from broadcaster Bob Costas [2]. The result provides an immediate spark for the Chicago roster as they compete for the top spot in their division [7].
