When fans talk about the longest World Series game ever, they aren't just measuring hours on a clock. They're talking about endurance, bullpen exhaustion, and October baseball at its most chaotic. The absolute record for the longest World Series game by innings stands at 18 innings, a feat achieved twice in Major League Baseball history. Both marathons share an uncanny connection: they took place in Game 3, they both involved the Los Angeles Dodgers, and both ended with dramatic walk-off home runs.
Understanding these historical contests requires looking beyond the basic box score. These games reshape rosters, test managerial strategy to its absolute breaking point, and force players to compete through pure exhaustion as the calendar ticks deep into the morning hours.
The 18-Inning Giants: Breaking Down the Record Marathons
Two legendary matchups share the crown for the most innings played in a single World Series game. Both contests stretched across six to seven hours, requiring teams to empty their benches and bullpens completely.
The 2018 Epic: Dodgers vs. Red Sox
On October 26, 2018, the Los Angeles Dodgers and the Boston Red Sox played a Game 3 that lasted 7 hours and 20 minutes. By the time Max Muncy launched a walk-off home run in the bottom of the 18th inning, it was 3:30 a.m. on the East Coast.
- Total Innings: 18
- Game Duration: 7 hours, 20 minutes
- Pitchers Used: 18 combined
- Total Pitches: Over 560
- Final Score: Los Angeles Dodgers 3, Boston Red Sox 2
Every available position player saw action, and managers had to get creative just to figure out who would pitch the next frame. The physical toll was immense, leaving both squads battered for the remainder of the series.
The 2025 Sequel: Dodgers vs. Blue Jays
History repeated itself in eerie fashion during Game 3 of the 2025 World Series. The Dodgers found themselves locked in another 18-inning postseason chess match, this time against the Toronto Blue Jays.
- Total Innings: 18
- Game Duration: 6 hours, 39 minutes
- Final Score: Los Angeles Dodgers 6, Toronto Blue Jays 5
Mirroring the 2018 thriller, this contest ended with a swing of the bat that shook Dodger Stadium. Freddie Freeman connected off Toronto reliever Chad Green to seal a 6-5 victory, locking down an unforgettable win after nearly seven hours of continuous play.

Other Memorable Extra-Inning World Series Marathons
While 18 innings represents the peak, several other Fall Classic games pushed players to their absolute limits.
The 2015 Opener: Royals vs. Mets
Game 1 of the 2015 World Series between the Kansas City Royals and the New York Mets went 14 innings. Lasting 5 hours and 9 minutes, the game featured intense momentum swings before Eric Hosmer hit a sacrifice fly in the 14th to give Kansas City a 5-4 win. This tone-setting victory helped propel the Royals toward their eventual championship title.
The 2005 Classic: White Sox vs. Astros
In Game 3 of the 2005 World Series, the Chicago White Sox and Houston Astros battled for 14 innings at Minute Maid Park. Clocking in at 5 hours and 41 minutes, the White Sox triumphed 7-5 to take a commanding 3-0 series lead. It was a grueling contest that heavily influenced Chicago's path to sweeping the series and breaking a decades-long championship drought.
The 1916 Pitchers' Duel: Red Sox vs. Robins
Long before bullpen games and pitch tracking, Game 2 of the 1916 World Series featured a 14-inning war of attrition between the Boston Red Sox and the Brooklyn Robins. Remarkably, despite lasting 14 innings, the entire game wrapped up in just 2 hours and 32 minutes. A 21-year-old Babe Ruth pitched 13 shutout innings for Boston, securing a 2-1 victory in what remains one of the most unique pitching performances in baseball lore.
How Longest-Game Marathons Impact Teams
Playing an 18-inning World Series game alters the competitive landscape of the entire series. Managers face immediate dilemmas that ripple through subsequent games.
- Bullpen Depletion: When a team burns through 9 or 10 pitchers in a single game, the next day's pitching staff is severely compromised. Relief pitchers have to work on short rest, increasing injury risk and vulnerability.
- Lineup Fatigue: Position players lose focus and physical stamina after standing on a field for nearly seven hours. Hitting metrics typically drop in subsequent games as hitters adjust to extreme physical tiredness.
- Tactical Shifts: Managers can no longer save their best pinch-hitters or defensive replacements for high-leverage spots in the late innings; everyone must be deployed just to survive the current frame.

Outside of the World Series, the absolute longest professional baseball game took place in the minor leagues between the Pawtucket Red Sox and Rochester Red Wings in 1981. That legendary minor league contest lasted 33 innings over multiple days before finally concluding.
How do modern extra-inning rules affect World Series games?
Major League Baseball implemented a runner-on-second-base rule for regular-season extra innings to shorten game times, but this rule does not apply to the postseason. World Series games continue under traditional extra-inning rules, meaning teams must play full traditional innings until a winner emerges organically.
