What is a walkoff in baseball?

A walkoff in baseball refers to a game-ending play, typically a hit or a home run, which results in the winning team scoring the final run needed to win the game. The term "walkoff" is derived from the idea that the winning team can simply walk off the field as the game is over. These plays are often dramatic and exciting, and are considered one of the most thrilling moments in baseball. Some of the most famous walkoff moments in baseball history include Bill Mazeroski's home run in Game 7 of the 1960 World Series, Kirk Gibson's walkoff home run in Game 1 of the 1988 World Series, and David Freese's walkoff home run in Game 6 of the 2011 World Series.
