Carlton Ernest Fisk, nicknamed "Pudge" and "the Commander", is an American former professional baseball catcher who played 24 seasons in Major League Baseball (MLB) for the Boston Red Sox and the Chicago White Sox. In 1972, he was the first player to be unanimously voted American League (AL) Rookie of the Year. Fisk is best known for his game-winning home run in the 12th inning of Game 6 of the 1975 World Series, during which he memorably waved his arms hoping for the batted ball to remain fair.

In baseball, a walk-off home run is a home run that ends the game. For a home run to end the game, it must be hit in the bottom of the final inning and generate enough runs to exceed the opponent's score. Because the opponent will not have an opportunity to score any more runs, there is no need to finish the inning and the teams can walk off the field immediately. The winning runs must still round all three bases and be counted at home plate. A variant of the walk-off home run, the walk-off grand slam, occurs when a grand slam exceeds the opponent's score in the bottom of the final inning and ends the game.
