what does walk off homerun mean in baseball
Walk-off home run 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 losing team (the visiting team) must then "walk off" the field immediately afterward, rather than finishing the inning. The winning runs must still be counted at home plate. This scenario can only occur if the visiting team is tied or leading after the top half of the inning.
Opening Day Opening Day is the day on which professional baseball leagues begin their regular season. For Major League Baseball and most of the minor leagues, this day typically falls during the first week of April.
Stolen base A stolen base most often occurs when a baserunner advances to the next base while the pitcher is pitching the ball to home plate.
Walk-on (sports) The term walk-on is used in sports, particularly American college athletics, to describe an athlete who becomes part of a team without being recruited beforehand or awarded an athletic scholarship. This results in the differentiation between "walk-on" players and "scholarship" players.
