Definition
In baseball, an earned run is a run that scored without the aid of errors or passed balls. It's a measure of a pitcher's effectiveness, showing how well they prevented runs when playing cleanly. Think of it as a 'clean' run allowed due to the pitcher's performance alone. A pitcher wants to minimize these! It reflects solely on their pitching skill, disregarding defensive miscues. If a batter gets on base because of a hit and scores, that's an earned run. If a batter reaches base due to an error, then scores, itβs typically NOT an earned run.
