Earned run

In baseball, an earned run is any run that was fully enabled by the offensive team's production in the face of competent play from the defensive team. Conversely, an unearned run is a run that would not have been scored without the aid of an error or a passed ball committed by the defense. An unearned run counts just as much as any other run for the purpose of determining the score of the game. However, it is "unearned" in that it was, in a sense, "given away" by the defensive team.
