## Introduction to ERA in Baseball

ERA, or earned run average, is a statistic used in baseball to measure the number of earned runs a pitcher gives up over a given amount of innings pitched. It is an important statistic for measuring the effectiveness of a pitcher and is used in both professional and amateur baseball. This article will explain what ERA in baseball means and how it is calculated.

Earned Run Average (ERA) is a statistic used to measure the number of earned runs a pitcher gives up over a given amount of innings pitched. It is calculated by dividing the number of earned runs allowed by the number of innings pitched and multiplying the result by nine. An ERA of 4.00 or below is considered good and an ERA of 6.00 or above is considered poor.

## What Does ERA Measure?

ERA measures how well a pitcher does in preventing runs from scoring. It does not take into account non-earned runs such as those that were the result of an error or passed ball. Also, it does not take into account runs that were scored on relief pitchers.

ERA also does not measure the quality of a pitcher’s pitches. It only measures how effective the pitcher is at preventing runs from scoring.

## Calculating ERA

ERA is calculated by dividing the number of earned runs allowed by the number of innings pitched and multiplying the result by nine. The formula is:

• Earned Runs Allowed / Innings Pitched X 9 = ERA

For example, if a pitcher allowed three earned runs in six innings pitched, their ERA would be 4.50.
