The average ERA+ is set to be 100; a score above 100 indicates that the pitcher performed better than average, while below 100 indicates worse than average.
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.

In modern baseball, an ERA under 2.00 is considered exceptional and is rare. An ERA between 2.00 and 3.00 is also considered excellent and is only achieved by the best pitchers in the league. An ERA between 3.00 and 4.00 is above-average.
The formula for finding ERA is: 9 x earned runs / innings pitched. If a pitcher exits a game with runners on base, any earned runs scored by those runners will count against him. ERA should be an ideal evaluation of pitchers.
If you’ve got a pitcher on the hill that gives up an average of 3 runs or less per game, you’re going to win a lot of games. 3.00 to 3.50 - These are great ERA’s. Very bettable and very solid. 4.00 to 4.50 - This would be considered to be an average ERA.
In general, an ERA in the range of 4.00 – 5.00 is considered a good career ERA, with the best pitchers being below 2.00. According to Baseball Almanac, Ed Walsh is credited with holding the career record for ERA with 1.82.
WHIP reflects a pitcher’s propensity for allowing batters to reach base, therefore a lower WHIP indicates better performance. While earned run average (ERA) measures the runs a pitcher gives up, WHIP more directly measures a pitcher’s effectiveness against batters.

The live-ball era was the era in which baseball regained relevance and exploded in popularity.

How Do You Calculate ERA For a 7 Inning Game? It is an estimation of pitcher’s performance that is determined by dividing the total of earned runs allowed by the total of innings pitched and multiplying the result by 7.
H/9 represents the average number of hits a pitcher allows per nine innings pitched. It is determined by dividing a pitcher’s hits allowed by his innings pitched and multiplying that by nine. It’s a very useful tool for evaluating pitchers, whose goal is to prevent runs, which are usually scored by hits.
A hold is an unofficial statistic that measures the effectiveness of middle relievers. A hold is granted to a relief pitcher who enters a game with his team in the lead in a save situation, and hands over that lead to another reliever without the score having been tied in the interim.
