About ERA

Earned run average (ERA) is a metric that shows how many earned runs on average, a pitcher or team's pitcher, gives up over the course of nine innings. It is calculated by dividing earned runs by innings pitched then multiplying the result by 9. Generally, for ERA, lower is better. (Source)
