**One confirmed postseason walk-off has occurred so far in the 2026 MLB playoffs: Milwaukee's Jackson Chourio delivered a two-run RBI single in the bottom of the ninth to win NLDS Game 2 against San Diego.** The remaining schedule includes multiple ALCS and NLCS games plus a potential seven-game World Series, creating repeated opportunities in high-leverage, late-inning situations where bullpen matchups, extra-inning contests, and close scores often produce dramatic finishes. Series like the Guardians-Rays ALCS and Brewers-Dodgers NLCS have featured competitive pitching duels and occasional rallies, though no additional walk-offs have been recorded through the first LCS contests. Factors such as strong relief pitching, offensive depth in extra frames, and the pressure of elimination games will continue to influence the total.
