Question

what is ERA in base ball ?

Answer 1

The letters stand for Earned Run Average. It is a figure that tries to keep track of the number of runs a pitcher would give up if he were able to pitch a complete game every time he pitches.

When a run is scored by a baserunner that got on base while facing the pitcher on the mound at the time the baserunner reached base, that run gets added onto that pitchers' runs given up total. If the baserunner got on base via a hit or a walk, hit by pitch or a fielders choice, the run he would score is considered to be an "earned run". If the base runner gets on base via a fielding error by the defense, including the pitcher, than a run scored by that baserunner is "unearned" and does not get added on to the total "earned" runs a pitcher gives up. There are instances when other baserunners can be considered "unearned" and still get on base via hit, walk or hit by pitch but we won't get into that right now.

When the pitcher is done for the night and all of the baserunners he allowed to get on has either scored or left on base after the final out of the inning, you can begin to figure out the ERA. You do this by taking the total number of earned runs, lets use 3 as an example. You then divide that number, (3) by the total number of innings the pitcher has pitched, lets say 7 innings for this example. [If the pitcher leaves the game with one out in the 8th inning, you divide the earned runs in this case by 7.3, if he got two outs you'd divide it by 7.7].

Now, 3 divided by 7 is 0,4285714 and probably a lot more numbers so we'll stop at 0.4285714. Multiply that number with 9, (ie. 9 innings in a game). Now your total is 3.857yada yada yada. Round up if the thousandth digit is 5 or higher. So the pitchers ERA for that game is 3.86.

Keep learning about baseball. It's great!

Answer 2

ERA is Earned Run Average. It is a ratio of Earned Runs surrendered by a pitcher per 9 innings pitched. Earned Runs, like so many terms in baseball, is a defined term and thus not just the number of runs that may score. But alas, that is another question with an even longer response.

Answer 3

Earned Run Average
its the average of amount of runs that a pitcher gives up in 9 innings. the lower your ERA, the better. A good ERA would be around 3.00

Answer 4

Earned run average. THe ERA is calculated by the following formula: earned runs/ innings pitched x 9. ZNote that runs are only counted as "earned" if you give up a hit which scores a run, or if you walk some people, get taken out of the game, and the next batter gets a hit. The runs count as your "earned" runs.

Answer 5

ERA is Earned Run Average

Answer 6

Earned Run Average on a pitcher through 9 innings.

Answer 7

It does stand for Earned Run Average.

There is a formula to it:

Number of Earned Runs x 9 then divide that by the number of innings pitched.

Answer 8

an era is an Earned run average. the lower the better.

Answer 9

The number of earned runs a pitcher gives up per 9 innings pitched, and by definition does not count runs that were not his due to his fault (unearned runs).

Answer 10

EArned Run Average - how many points have been scored on this pitcher. The lower the ERA the better the pitcher..................
