Thanks. I have read 10.22 HUNDREDS of times, but this is the first time I saw this portion. Back to remedial reading for me. I am totally embarrassed.

You have? You need to get some better reading material!

I read many things; books, magazines, newspapers, etc.

What is "better reading" than OBR, and the various Rule Books? Especially when I umpired for 44 years, and still keep up on the rules as a fan.

I was using this formula before you were born. Try re-reading my post. I asked if there was a formula to use when there are 1/3 or 2/3 of an inning. Winky has nothing re: this.

blue, that was kind of rude, considering that even your reiteration of the question makes no sense. The formula is the same, whether the IP happens to be an integer or not. Simply plug your 9.333 or 30.333 or even 0.3333 into the formula. What's the issue?

2 runs, 5 innings - 2*9/5 = 3.60 ERA
2 runs, 5 1/3 innings = 2*9/5.333333 = 3.375 ERA

I'm glad you were able to calculate ERA before some of us were born - but I fail to understand why you can do so with integer IP's, but not any other IP's.

The "issue" is, that I hadn't read 10.22 fully before. As for rude, tough noogies. The guy gave me no valid answer. And for you, I'm not a mathematician, and don't understand your gobbledygook.

No offense, here, but he gave you a perfectly valid answer. I don't think he could have assumed that the real problem here was that you didn't understand fractions. Heck (and again, no offense intended - I normally expect very solid postings and opinions from you), my 8-year old knows that 1/3 is 0.333333333... I think it's fair for us to assume that you did too.

Do you consider this a valid answer: "Originally Posted by SAump

This did NOT answer what I asked. The problem wasn't my not knowing fractions. I know fractions. But until I was shown the section of 10.22 that mentions fractions, I was unaware of using fractions in determining ERA, though I did use that system, because it made sense. But I couldn't find anything in print to validate it. I must take blame for not reading 10.22 more carefully earlier, because I hadn't noticed the mention of fractions.

Is this ERA stat only used to compare 9-inning games? Other leagues playing within appropriate age levels only allow 5, 6 or 7 inning ballgames. For example, a young child with a 6.00 ERA over 9-innings would lower his ERA to a 4.00 ERA over 6-innings. Shouldn't we adjust the ERA formula to match the number of innings at each particular age level?
