In baseball, a walk-off home run is a home run that ends the game. It must be a home run that gives the home team the lead (and consequently, the win) in the bottom of the final inning of the game. Thus the home team can walk off the field immediately afterward, rather than finishing the inning. The winning runs must still be counted at home plate.
A 'walk off' is a hit, or any other action, in the bottom of the 9th inning or the bottom any inning after that, which drives in the game-winning run. It is so named because since the earned run ends the game immediately, everyone can walk off the field. + 342 others found this useful.
