A walk-off home run is a specific type of game-winning run that occurs when the home team scores the winning run in the bottom of the ninth inning or any extra innings. It must be a home run that gives the home team the lead in the bottom of the final inning of the game - either the 9th inning, any extra inning, or any other regularly-scheduled final inning. The term "walk-off" comes from the fact that the teams can walk off the field immediately afterward, as the opponent will not have an opportunity to score any more runs. The winning runs must still round all three bases and be counted at home plate. A walk-off can be recorded in many ways, including a hit, an error, a walk with the bases loaded, a hit by pitch with the bases loaded, a sacrifice fly, an out (with less than two outs in the inning), a wild pitch, a passed ball, and a balk. Walk-off home runs are the second most common type of walk-off wins and are a fan favorite. They are uncommon enough to be dramatic when they occur, especially during the postseason. Walk-off celebrations typically consist of an entire baseball team leaving the dugout to meet a player at home plate.
