	rdfs:comment """{{sabermetric | formula = \text{ERA} = 9 \times \frac{\text{earned runs allowed}}{\text{innings pitched}}}}
In baseball statistics, earned run average (ERA) is the average of earned runs allowed by a pitcher per nine innings pitched (i.e. the traditional length of a game). It is determined by dividing the number of earned runs allowed by the number of innings pitched and multiplying by nine. Thus, a lower ERA is better. Runs resulting from passed balls, defensive errors (including pitchers&#39; defensive errors), and runners placed on base at the start of extra innings are recorded as unearned runs and omitted from ERA calculations.
