To figure ERA take the total number of earned runs and multiply by 7 (which is a complete game in softball) then divide by innings pitched.

same as mlb but per w/e amount of innings they have

take the earned runs multiply by 9 and divide it by innings pitched. to be exact, go to the nearest 100th of a percentage point.

ERA is based on 9 innings pitched. When you see a pitcher with a 4.94 ERA that means for every 9 innings pitched, he gives up 4.94 earned runs. Example: A pitcher has pitched 150 innings and given up 60 earned runs. 1) Divide the number of earned runs (60) by the number of innings pitched (150) =0.40. 2) Then take that number (0.4) and multiply it by 9 =3.60. A pitcher who has pitched 150 innings and given up 60 earned runs has an ERA of 3.60.

To calculate ERA, you take the the number of earned runs allowed, multiply by nine, then divide by the number of innings pitched

A pitcher's era (earned run average) is calculated as follows: 1. Number of Earned Runs 2. Times 9 3. Divided by number of innings pitched So, if a pitcher gives up 3 earned runs in 5 innings then we first multiply 3 times 9 = 27. Then we take 27 and divide it by 5 (for innings pitched) to get an era of 5.4. Also, an earned run is a run that scores without the defense creating any errors.

1) Multiply the total number of earned runs by the number of innings in a full game (most fastpitch leagues play 7 inning games but some youth leagues play 6 inning games). 2) Divide the total number of innings pitched into the number derived from 1) above and round to the second decimal place. Using 17 innings pitched and 4 earned runs ... For games that are 7 innings in length, the ERA would be 1.65 (4 times 7 equal 28 and 28 divided by 17 equal 1.647 which is rounded to 1.65). For games that are 6 innings in length, the ERA would be 1.41 (4 times 6 equal 24 and 24 divided by 17 equal 1.411 which is rounded to 1.41).

That's the pitcher's Earned Run Average, i. e., the number of earned runs the pitcher allows per nine inning. To arrive at the ERA, take the number of earned runs, multiply by 9 and divide by the number of innings pitched.

ERA stands for Earned Run Average. The number of innings per game determines how ERA is calcuated. In Major League Baseball they play 9 innings so ERA is calculated with this equation, Earned Runs divided by 9. High School baseball (at least where I am located) plays 7 innings as a regulation length game. In this case a pitcher's ERA is Earned Runs divided by 7. In Little League the a regulation game is 6 innings, so ERA would be determined by Earned Runs divided by 6. If you are playing a game and it goes in to extra innings then a pitcher's ERA is not affected by the extra innings. If a regulation game is 6 innings, and the game goes into the seventh inning, then a pitcher's ERA is still determined by # of earned runs divided by 6. In summary ERA is ALWAYS determined by the amount of Earned Runs allowed divided by the number of innings played (not including extra innings).

ERA is Earned Run Average. An earned run is a run that is scored by a batter that reached base while a pitcher was on the mound, so long as the batter did not reach base on an error. Example A: If Pitcher A gives up a a single, then a home run, Pitcher A acquired 2 earned runs. Example B: If Pitcher B gives up a ground ball to the second basemen who mishandles the ball allowing the runner to reach first, and then Pitcher A gives up a home run, only 1 earned run is acquired. Example C: Pitcher C gives up a single and then is is yanked from the game. Pitcher D comes in for relief and gives up a home run. Pitcher C acquires 1 earned run for the runner on first, and Pitcher D acquires an earned run for the batter that hit the home run. Earned Run Average is calculated by determining how many earned runs a pitcher averages over nine innings. Each full inning is counted as one. If a starting pitcher is pulled from the mound with one out in the seventh inning, he pitched 6 full innings plus one third of an inning = 6 1/3 innings (this is written 6.1 innings). Lets say he gave up 4 earned runs this outing: Take 4 earned runs and divide by 6 1/3 innings and multiply by 9 innings in a game = an ERA of 5.68. Over the course of a season the numbers will get larger. In 2002, Greg Maddux gave up 58 earned runs while pitching 199.1 innings. Take 58 earned runs and divide by 199 1/3 and then multiply by 9 innings in a game = 2.62 ERA.

Supposing that all four runs were earned runs and it is a nine inning game, the ERA is 4.5... Earned runs divided by innings pitched multiplied by the the total innings of a standard game (4/8 * 9 = 4.5)

Earned runs are runs that are scored because of hits stolen bases. Un-earned runs are those where a runner gets on base because of an error and eventually scores. The earned run average (ERA) is calculated by taking the total number of earned runs scored against a pitcher and dividing that by the total number of innings that pitcher pitched. The lower the ERA the better the pitcher, usually.

Pitch more shutout innings - that is, innings where you don't give up an earned run. ERA is calculated by taking the number of earned runs a pitcher gives up, dividing it by the number of innings he/she pitched, then multiplying the result by nine. So, for example, if a pitcher has six complete innings and gives up two earned runs, their ERA becomes three (2 divided by 6 is 1/3, 1/3 multiplied by nine is 3). This works over the course of a pitcher's career, so if a pitcher gives up six earned runs over six innings in one game, his/her ERA becomes nine. If he/she then pitches a complete game shutout (nine full innings, no earned runs) their ERA drops to 3.6 (as it is now six earned runs from fifteen innings).

Earned Run Average per 9 innings It shows for every nine innings a pitcher pitches how many runs he has averaged to gived up. This does not include unearned runs (ie runs given up because of errors). Caluclation (Earned Runs/number of innings pitched)*9 innings

It is a measure to judge how effective a pitcher is. It calculated by taking the total earned runs a pitcher has allowed and dividing by (total #of innings pitched/9). Giving you an average number of runs a pitcher allows (earned runs) every 9 innings

1) 1.82 - Ed Walsh - 598 earned runs in 2964 1/3 innings between 1904-1917. 2) 1.89 - Addie Joss - 488 earned runs in 2327 innings between 1902-1910. 3) 2.02 - Jack Pfiester - 240 earned runs in 1067 1/3 innings between 1903-1911. 4) 2.03 - Joe Wood - 324 earned runs in 1436 1/3 innings between 1908-1920. 5) 2.05 - Jim Devlin - 320 earned runs in 1405 innings between 1875-1877. The current (through games of 4/22/09) pitcher with the lowest ERA with 1000+ innings pitched is Mariano Rivera of the New York Yankees with 2.27 - 260 earned runs in 1030 2/3 innings pitched.

2.76 in the regular season (713 earned runs allowed in 2324 1/3 innings pitched) and 0.95 in the World Series (6 earned runs in 57 innings pitched).

In MLB, for pitchers that threw at least 162 innings in a season, that would be Dutch Leonard who had an ERA of 0.96 for the Boston Red Sox in the 1914 season. Leonard pitched 224 2/3 innings and gave up 24 earned runs. For pitchers that threw at least 100 innings in a season it is Tim Keefe who had an ERA of 0.86 for the Troy Trojans in 1880. Keefe pitched 105 innings and gave up 10 earned runs.

it is earned runs per nine innings pitched

Bob Gibson's regular season ERA was 2.91 (1258 earned runs in 3884 1/3 innings pitched) and his World Series ERA was 1.89 (17 earned runs in 81 innings pitched).

Earned Runs Average is computed by the formula: 9 x (Earned Runs Allowed/Innings Pitched). For example, if a pitcher threw 7 complete innings, allowing 4 earned runs, the formula would be: 9 x (4/7) = 5.14 ERA.

earned runs average

yes

ERA is the average number of earned runs a pitcher allows per nine innings pitched.

Moose Haas. Haas had an ERA of 3.10 for the Brewers in 1980, giving up 87 earned runs in 252 1/3 innings. His ERA was 6th best in the American League. Relievers Bill Castro (2.72 ERA on 26 earned runs in 84 1/3 innings) and Bob McClure (3.08 ERA on 31 earned runs in 90 2/3 innings) had lower ERAs but did not pitch enough innings to qualify to be in the running for the ERA title.
