Marathon on the Mound: The Longest Baseball Game Ever and How History Was Made

Baseball is a game of strategy, skill, and sometimes, sheer endurance. For fans and players alike, there are few spectacles more impressive than a game that drags on into the night — one that challenges pitchers, hitters, umpires, and spectators alike. In this article, we’ll explore the phenomenon of the longest baseball game ever, both in general professional play and within the major-league and World Series contexts. We’ll answer questions like what was the longest baseball game ever, what is the longest MLB game, and what is the longest World Series game — all while peppering in key phrases like longest MLB game, longest world series game ever, how many innings was the longest World Series game, walk­off home run, and more.

What defines “longest” in baseball?

When we talk about the “longest baseball game,” we need to clarify what metric we’re using:

• By innings: How many innings were played.

• By elapsed time: How long the game took from first pitch to the end.

• By competition level: Major League Baseball (MLB), minor leagues, the World Series (MLB postseason), etc.

Different records apply depending on the level and metric. Let’s start broad and then drill into the standout games.

The longest baseball game ever in professional baseball (all levels)

If you include all levels of professional baseball (not just MLB), the ultimate endurance test came in the minor leagues.

• The game between the Pawtucket Red Sox and the Rochester Red Wings (Triple-A International League) in 1981 lasted 33 innings and more than 8 hours (8 h 25 m).

• The game was started April 18 & 19 and resumed June 23 at the same site.

• Because it spans the minor leagues, this is the widely recognised “longest professional baseball game ever”.

While not strictly MLB, this game sets the high‐water mark for how long a baseball game can go if the contest continues without being called. It’s worth referencing when discussing “what was the longest baseball game ever.”

The longest game in MLB history (regular season)

Turning to MLB (major league level), the records shift.

• The longest game in MLB by innings took place on May 1, 1920: the Brooklyn Robins vs. Boston Braves played to a 1-1 tie over 26 innings.

• The game lasted just under four hours despite the insane number of innings (3:50) because of the pace of play and era.

• Therefore, when someone asks “longest MLB game” without specifying postseason or time, this 26-inning tie is often cited.

Other long MLB games (by time) exist, but this innings total remains the record.

The longest World Series game ever

The stakes get even higher when we focus on the postseason, and specifically the World Series.

• The record for the longest game in World Series history (by innings and time) is held by Game 3 of the 2018 World Series between the Los Angeles Dodgers and the Boston Red Sox.

• That game lasted 18 innings (so 9 extra innings beyond the standard 9).

• The elapsed time: 7 hours 20 minutes.

• The final score: Dodgers 3, Red Sox 2.

• The winning hit was a walk-off home run by Max Muncy in the 18th inning.

So, if you search terms like “what is the longest world series game”, “longest game in world series history” or “how many innings was the longest world series game” — the answer is 18 innings (in 2018).

Why this particular World Series game matters

A deeper dive into the significance:

1. Endurance test: For players, coaches and umpires, staying sharp deep into an 18-inning battle is rare.

2. Walker-off theatre: A walk-off home run means the trailing team finishes the game at bat with a decisive scoring play — perfect dramatic flourish. Muncy’s blast sealed a long night in spectacular fashion.

3. Record-setting: It broke previous World Series records for both innings played and elapsed time.

4. Historical impact: It’s now a reference point whenever discussions arise about marathon postseason games.

Other notable marathon games and records

To give further context beyond the single biggest mark, here are other important records and “near-marathons” in baseball:

• The longest 9-inning MLB game by time: On August 18, 2006, the New York Yankees beat the Boston Red Sox 14-11 in 4 hours 45 minutes.

• The 2005 World Series featured a game that lasted 14 innings (Game 3: Chicago White Sox vs. Houston Astros) with a duration of 5 h 41 m.

• For
  “what is the longest game in MLB history” (regular season, by innings) — 26 innings.
  “what is the most innings played in a World Series game” — 18 innings (2018 WS G3).

The human side: What does a marathon game feel like?

Beyond numbers, these marathon games carry emotional and physical weight:

• For players: Pitchers must dig deep into their arsenals, relievers may be depleted, positional players may fatigue, and mental endurance becomes as important as physical skill.

• For fans: Sitting through extra innings means staying alert well past typical game time, often late into the night (or early morning). The suspense builds with every extra inning.

• For teams/coaches: Strategy shifts. Bullpen management becomes crucial. The risk of injury or fatigue increases.

• For history: These games become part of lore. When someone asks “what’s the longest World Series game”, there’s one clear answer.

For example, in the 2018 game the fact that the winning blow was a walk-off home run adds narrative drama: one swing ended an epic battle.

Why such games are rare today

Several factors explain why marathon games don’t happen as often:

• Modern pitching strategy: Teams limit pitch counts, use specialized relievers, and rotate bullpens more than in earlier eras. This makes it less likely for starting pitchers to go extremely deep and for games to drag because of fatigue.

• Pace of play initiatives: MLB has introduced rules like the pitch clock, bigger bases, stricter time between pitches, and automatic intentional walks to speed up games.

• Television/commercial considerations: Longer games affect scheduling, ad breaks, and viewer attention spans, so there’s institutional pressure for games to proceed efficiently.

• Player health concerns: Extended games mean increased risk of injury, especially for pitchers. Teams are more cautious.

Thus, when a game drags on 15, 16, 17+ innings nowadays, it becomes a talking point precisely because it’s unusual.

The legacy of the 2018 World Series Game 3 – longest world series game

Let’s revisit some details of that record-breaking game for emphasis:

• It started on October 26, 2018, at Dodger Stadium in Los Angeles and finished early on October 27.

• Home runs: The Dodgers’ Joc Pederson homered in the 2nd; the Red Sox’s Jackie Bradley Jr. tied it with a solo shot in the 8th.

• It remained tied until the 18th inning when Max Muncy launched the walk-off home run to seal the win.

• The time: 7 hours, 20 minutes. That’s longer than many entire World Series combined in earlier eras.

• Because of its length and drama, it is referenced in record lists like the Guinness World Records.

This game now holds the title for longest WS game by innings and time. Whenever the phrase “longest game in World Series history” appears, this is what people mean.

How many innings is too many?

From a rules standpoint, extra innings continue until one team leads after a completed inning (unless special rules apply). So in theory, there’s no upper limit in MLB for innings played — the game could go on indefinitely if neither team scores. That’s why we can see 26-innings, 18-innings, 33-innings games.

But some metrics to keep in mind:

• In the major league regular season, finishing 20+ innings is extremely rare.

• In the World Series, the record is 18 innings.

• Most extra-inning games end well before that.

Thus when a game reaches 15+ innings it becomes one for the ages.

Walk-off home runs and extra innings

A talk of longest games inevitably brings in dramatic endings — for example, the walk-off home run. When a game is tied in extra innings and the home team wins by scoring in its final at-bat, that’s a walk-off. In the longest World Series game:

• Max Muncy’s homer in the 18th inning was a walk-off.

• The term “walk-off” itself shows the dramatic nature of such a finish: one swing, one moment, after a marathon.

So when keywords like “walk off home run” appear in searches tied to long games, this is a key linkage.

Implications and why fans remember these games

• Historical significance: These games become part of baseball lore. Future players and fans reference them.

• Statistical oddities: They produce unusual stats — e.g., pitchers throwing deep into extra innings, many batters faced, etc.

• Emotional impact: For players the fatigue and pressure mount. For fans, staying late or witnessing a walk-off in the 18th feels unforgettable.

• Record benchmarks: They set new “longest” standards that search queries look to uncover: “what was the longest mlb game”, “what was the longest world series game”, etc.
