The longest World Series game on record lasted 18 innings and 7 hours 20 minutes. That mark was set in Game 3 of the 2018 World Series between the Los Angeles Dodgers and the Boston Red Sox, a game eventually won by the Dodgers on a walk-off. A more recent 18-inning affair in 2025 between the Dodgers and Blue Jays matched the 18-inning length, clocking in at about 6 hours and 39 minutes, tying the all-time record for World Series endurance. In terms of total innings, several 14-inning games also rank among the marathon matches, with durations typically ranging from roughly 5 to 6 hours, depending on pace and pauses in play.
