Note: For our leaderboards, a walk-off hit is defined as any hit in the bottom of the final inning of a game in which the RBIs generated on the play ended the game. For example, if the winning run was charged as an error, even if that error occured after a credited hit, that would not count for this leaderboard. The hit must be credited as batting in the winning run(s).
