An ERA is an acronym for earned run average. An ERA is the calculated mean of runs earned by a pitcher for every nine innings the pitcher pitched. An ERA is calculated by multiplying the total number of runs the pitcher gets by nine and dividing the result of that calculation by the number of innings pitched by the player. In this article, you would learn what a good ERA is for a closer and many other things about baseball ERAs and closers.

**What is a good era for a baseball closer?**

The value considered a good era is changed yearly, a century and a decade ago, there was a consensus in baseball that an era below 2.0 was a good one. A good era increased to below 4.00 a decade after, in the 1920s-1930s. Nowadays, eras under 4.00 are viewed as good eras by the baseball community. For a baseball closer, a good era is typically between the values of 2.00 and 3.00. This simply means that the average baseball pitch of a closer would averagely lead to between two and three runs for every nine baseball innings in a game.

**The formula for calculating eras in baseball **

An ERA is a very important baseball statistics calculation for baseball pitchers. The importance of calculating eras is due to the need to measure the effectiveness of baseball pitchers. The other two important baseball statistics calculations for baseball pitchers are Wins and also Strikeouts. Let’s get right into the method of calculating a baseball ERA. Here is the formula for baseball era calculation:

ERA= ER/IP ×9

The result of the above baseball statistics calculation is then rounded off to a figure with two dp( two decimal places).

**Steps for calculating eras in baseball **

Here are three steps for you to take to be able to accurately calculate baseball ERA:

- Divide the runs earned by each pitcher by the number of innings the pitcher pitched: This is the first step in the baseball era calculation process. It is important for whoever is calculating these baseball statistics to note that every out a baseball pitcher makes counts as 1/3 of a pitched inning. This means that a baseball pitcher who successfully pitches seven innings and comes back in for the eighth inning and gets that eight innings out, that pitcher would have a total of 7 1/3 as his innings when put into decimal, that is 7.33 baseball innings for that pitcher. It is also important for whoever is calculating the baseball era of a pitcher to note that only earned runs are used for calculating baseball ERAs. If a baseball runner scores because of a defensive error made by the opposing baseball team, that would not count as a baseball earned run and therefore would not count when calculating the effectiveness of a baseball pitcher.
- Multiply the result of the aforementioned calculation: After dividing the number of runs earned by the pitcher by the number of innings the pitcher pitched, the next thing for the person calculating the baseball era of a pitcher to do is to multiply the result of the division by 9. It should be multiplied by 9 because a standard game of baseball has a total of 9 innings. The era would therefore tell us how many runs a pitcher would earn within the timeframe of 9 innings. In games like baseball high school games or softball games, there are only 7 innings, so the era calculation would be modified. Instead of multiplying by nine, the person calculating would multiply by seven. If it is a little league baseball game that only has six innings, the person calculating the era would have to multiply by six instead of nine.
- Round the result to two decimal places: The last step in calculating baseball eras is to round off the result of your previous calculation to two decimal places. Rounding off the result of the baseball era calculation to two decimal places is important to make it very easy to understand. It would be difficult for interested people in the era of a baseball pitcher to understand the information if the result of the era calculation has a very long or recruiting decimal place.

**Who are closers in Baseball?**

A closer or closing pitcher in baseball is a pitcher whose responsibility is to get the final outs in a baseball game where his team is leading with a very close margin. This player is usually brought on to pitch the few outs that would help the baseball team to see off the game and ensure that it ends up in a win for them, the term for this activity by baseball closers is a “save”. Closers generally finish winning games but are not usually credited for the pitches that made their team win. For closer in a baseball game, a good era is usually between 2.00 and 3.00 because the baseball closer does not see much baseball action, and his job is to ensure that the team sees out the game, therefore an era between 2.00 and 3.00 reflects a very effective baseball closer.

**Conclusion**

Baseball-era calculations are very important for coaches and other people who are in charge of baseball teams. They are important because you as the baseball coach have to determine how effective your baseball throwers are and how to make them improve in their pitching game. Generally, ERA calculations are done at the end of the season, this helps the MLB to calculate and rank the effectiveness of pitchers around the country. But, as a baseball coach, you can calculate the era of all the throwers in your baseball team, including the closers to evaluate their effectiveness on a baseball game-by-game basis or a week-by-week basis. Apart from baseball eras, there are other statistics that modern-day baseball coaches and team handlers use to measure the effectiveness of their baseball closers, this statistic is the save. The save is a wholesome calculation of the efficiency of the closer, and it has helped a lot of teams to improve the skills of their baseball closers and helped them achieve a lot of baseballs wins because of this improvement in their baseball closer’s skills.
