What Does Walk-Off Home Run Mean in Baseball?

By Emma Wilson · May 8, 2027

A walk-off home run in baseball occurs when a batter hits a home run in the bottom of the final inning that gives their team enough runs to win the game immediately, ending the game on the spot.

What Is a Walk-Off Home Run?

In baseball, a walk-off home run is one of the most dramatic ways to end a game. It happens when the home team hits a home run in the bottom of the ninth inning or later, turning a tie or deficit into a lead, thus making further play unnecessary. The term "walk-off" refers to the fact that players can literally walk off the field once the winning run scores.

Key Conditions for a Walk-Off Home Run

The home team must be batting in the bottom half of an inning.
The game must be either tied or the home team must be trailing by no more than three runs (since a home run can score up to four runs).
The home run must provide the winning margin, ending the game instantly.
It can occur in the ninth inning or any extra inning.

History and Origin of the Term "Walk-Off"

The phrase "walk-off" was popularized in the late 1980s by pitcher Dennis Eckersley, who used it to describe game-ending home runs he had given up. Initially, he used it negatively—referring to the moment when he had to walk off the mound in defeat. Over time, the term evolved into a celebratory phrase for the offensive player who ends the game with a decisive hit.

Before "walk-off" became common, such moments were simply called "game-winning homers," but the modern term emphasizes the immediate conclusion of the game.

Types of Walk-Off Hits

While a walk-off home run is the most powerful version, other types of walk-off hits exist:

Walk-off single: A base hit that scores the winning run.
Walk-off double/triple: Less common due to baserunning requirements.
Walk-off sacrifice fly: A fly ball that brings in a run with less than two outs.
Walk-off error: A defensive mistake that allows the winning run to score.

However, the walk-off home run remains the most iconic because it requires no assistance from the defense and often clears the bases.

Frequently Asked Questions About Walk-Off Home Runs

Can a walk-off home run happen in extra innings?

Yes, a walk-off home run can occur in any extra inning as long as the home team is batting in the bottom half and the home run results in the winning run.

Does a walk-off home run always win the game?

Yes, by definition, a walk-off home run ends the game immediately because it produces the winning run during the home team's at-bat in the final inning.

Can there be multiple runs scored on a walk-off home run?

Absolutely. If the bases are loaded, a walk-off home run can score up to four runs, all of which count since the game ends only after the winning run crosses the plate.

Who holds the record for most walk-off home runs in MLB history?

Jimmie Foxx and Mickey Mantle are tied for the most career walk-off home runs with 12 each, according to historical MLB data.

Is a walk-off possible if the visiting team is leading?

No. Since the home team always bats last, only they can produce a walk-off hit. If the visiting team is leading in the final inning, the game ends when the home team fails to catch up.
