Chicago/Pittsburgh (Union League) Earned Runs Charts and Records
About Earned Runs
An earned run is a run scored by the opposing team that is considered a direct result of the pitcher's actions. For example, a home run is counted as an earned run since the pitcher is directly responsible for the hit, whereas a player who scores because of a position player's defensive error, or who advanced bases due to a position player's defensive error, is not an earned run. Generally, for Earned Runs, lower is better. (Source)
