A walk-off in baseball happens when the home team scores the winning run in the bottom of the ninth inning or later, ending the game immediately.
Only the home team can record a walk-off because it bats second in each inning. Once the home team takes the lead in the bottom of the final inning, the visiting team does not get another turn at bat.
A walk-off also does not have to be a home run. It can happen on a single, walk, sacrifice fly, error, wild pitch, or several other plays.
Here’s a simple example:
Bottom of the ninth. The score is tied 3–3. A runner is on second base.
The batter singles into right field, the runner scores, and the home team takes a 4–3 lead.
The game ends right there.
That is a walk-off.
What Does Walk-Off Mean in Baseball?
A walk-off describes how a baseball game ends, not one specific type of hit.
The key is that the home team scores the run that puts it ahead in the bottom of the final inning.
MLB defines a walk-off as a situation where the home team takes the lead in the bottom of the ninth inning or an extra inning and the game ends immediately.
Why Can Only the Home Team Get a Walk-Off?
The visiting team bats in the top half of every inning.
The home team bats in the bottom half.
If the visiting team takes the lead in the top of the ninth, the home team still gets a chance to bat.
But if the home team takes the lead in the bottom of the ninth, there is no need for another inning. The visitors have already completed their turn.
That is why a road team cannot record a walk-off.
If you are still learning how innings work, see this guide to how many innings are in baseball explains regulation and extra innings in more detail.
What Types of Plays Can Be Walk-Offs?
A walk-off can happen in several different ways.
Walk-Off Home Run
This is the most famous type.
A batter hits a home run that gives the home team the lead in the bottom of the ninth or later.
Because the home run produces the winning run, the game ends as soon as the play is completed.
Walk-Off Single
A home run is not required.
Imagine the game is tied with a runner on second base.
The batter hits a single into the outfield, the runner scores, and the home team wins.
That hit is a walk-off single.
Walk-Off Walk
A game can even end without the batter putting the ball in play.
If the bases are loaded in a tie game and the pitcher throws ball four, the runner on third is forced home.
That winning run makes it a walk-off walk.
Walk-Off Sacrifice Fly
Suppose the game is tied with a runner on third and fewer than two outs.
The batter hits a deep fly ball, the runner tags up, and scores after the catch.
If that run gives the home team the lead, the sacrifice fly becomes a walk-off.
Other Walk-Off Plays
MLB also notes that walk-offs can result from an error, hit by pitch, wild pitch, passed ball, or even a balk.
The type of play can change.
The requirement does not:
The home team scores the winning run and the game ends.
Can a Walk-Off Happen in Extra Innings?
Yes. A walk-off is not limited to the ninth inning.
If the score is tied after nine innings, the game continues into extra innings.
The home team can then walk it off in the 10th, 11th, 12th, or any later inning.
For example, if a team enters the bottom of the 10th tied 5–5 and scores a run, the game ends immediately with a walk-off win.
Walk-Off vs. Game-Winning Hit
A walk-off and a game-winning hit are not always the same thing.

Walk-off |
Gives the home team the lead and immediately ends the game |
|
Game-winning hit |
Produces the run that ultimately decides the game, but can happen earlier |
For example, a player could hit a two-run homer in the sixth inning to put his team ahead 4–2.
If the final score stays 4–2, that homer provided the winning margin.
But it was not a walk-off because the game continued for several more innings.
A walk-off must end the game immediately.
Why Is It Called a Walk-Off?
The term is commonly credited to Hall of Fame pitcher Dennis Eckersley.
He used the phrase to describe a game-ending home run where the losing pitcher could simply “walk off” the field after giving it up.
Over time, the term expanded beyond home runs.
Today, “walk-off” can describe almost any play that gives the home team the winning run on the final play of the game.
The Bottom Line
A walk-off happens when the home team scores the winning run in the bottom of the final inning and the game ends immediately.
It can happen in the ninth inning or extra innings.
And it does not have to be a home run.
A single, walk, sacrifice fly, error, wild pitch, or another game-ending play can all produce the same result:
The winning run scores, the game is over, and the home team walks off the field with the win.
