The longest World Series game in history is Game 3 of the 2018 World Series between the Los Angeles Dodgers and Boston Red Sox, which lasted 18 innings and 7 hours 20 minutes, ending in a 3–2 Dodgers win on a Max Muncy walk-off home run.

Core details

  • Matchup: Los Angeles Dodgers vs. Boston Red Sox in Game 3 of the 2018 World Series.
  • Innings played: 18 innings, the most ever in a World Series game (tied only by later 18-inning marathons, but still the longest by time).
  • Duration: 7 hours 20 minutes, the record for the longest World Series game by time.
  • Final score: Dodgers 3, Red Sox 2.
  • Deciding moment: Max Muncy hit a walk-off home run in the bottom of the 18th inning to end the game.

How it compares to other marathons

Several other World Series games have gone very long, but none have surpassed the 2018 epic in total time. A more recent example is Game 3 of the 2025 World Series (Dodgers vs. Blue Jays), which also went 18 innings but lasted “only” around 6 hours and 40–50 minutes, still shorter than the 2018 game.

Why this game stands out

  • The 2018 Game 3 combined marathon length with high stakes, as it was a pivotal game in a championship series between two powerhouse franchises.
  • Players, managers, and fans described the experience as exhausting and surreal, with the late‑night walk-off turning what felt like an endless grind into instant classic status in World Series lore.
