Earned Run Average
An earned run is a run that the pitcher is held responsible for so if the pitcher gives up a home run that 1 earned run you probably already knew that. Instead if the pitcher pitches and then the ball is hit into the outfield and a outfielder drops it and a run comes in that would not be an earned run.
