How Long Do Baseball Games Last?

A Major League Baseball game now lasts about 2 hours and 40 minutes on average. That's noticeably shorter than it used to be — games regularly ran past 3 hours and 10 minutes before the pitch clock was introduced in 2023, which cut roughly half an hour from the average almost immediately.

That rule change is why older answers to this question are wrong, and why your memory of long games isn't mistaken.

Typical lengths by level:

Why baseball has no clock. Unlike football or basketball, baseball is not timed. A game lasts until nine innings are complete and one team is ahead. This means no game has a guaranteed end time, and the length depends entirely on what happens.

The pitch clock and what changed. From 2023, MLB pitchers have a limited time to begin their delivery — 15 seconds with the bases empty and 18 seconds with runners on — with a violation costing an automatic ball. Batters must be set in the box with time remaining. Alongside limits on pickoff attempts and bigger bases, this cut about 24 minutes from the average game in the first season, the largest single-year drop in the sport's history.

How many innings are in a baseball game? Nine in professional and college baseball. High school plays seven, and Little League usually six. Each inning has a top and a bottom, and each half ends after three outs, so a full game is a minimum of 54 outs.

Two things shorten a game:

• The home team leading after the top of the 9th. They don't bat, so the game ends after 8½ innings. This happens often.
• Weather. A game called after five complete innings (4½ if the home team leads) counts as official and the result stands.

Extra innings. A tie after nine goes to extra innings, played until one team is ahead at the end of a full inning. Since 2020 the regular season uses the automatic runner on second base to start each extra inning, which resolves most games quickly. The postseason does not use it, which is why playoff games can run very long. The longest MLB game on record went 26 innings in 1920.

What makes a game run long:

• High-scoring games — more batters, more pitching changes
• Pitching changes, each requiring warm-up
• Lots of walks and deep counts
• Replay reviews
• Rain delays, which can add hours and aren't counted in the playing time
• Playoff baseball, with longer commercial breaks and more deliberate managing

What a fan should actually plan for: allow 3 to 3½ hours at the ballpark. Even though the game averages 2h40m, you'll want time for getting in, and there's always a chance of extras or a delay.

What is a perfect game? A related question worth knowing: a perfect game is when a pitcher faces the minimum 27 batters and none reaches base — no hits, no walks, no errors. It has happened only 24 times in MLB history. A no-hitter is less strict, allowing baserunners via walks or errors as long as no hits are given up.

Other rules that affect pace: the designated hitter is now used in both leagues, which slightly raises scoring, and seven-inning doubleheaders were used temporarily but have since been dropped.
