Baseball question: Does anyone know why an out counts as 1/10th of an inning instead of 1/3rd of an inning when it comes to representing total Innings Pitched? <br /><br /> Have I phrased that clearly enough? When a pitcher pitches 7 innings, and gets one out in the eight, it goes down as "7.1" innings pitched. Two-thirds of an inning is *.2 -- but why? Why? <br>
<br>
And why do we persist on using that inaccurate number for calculating things like ERA? Is it because, in the long run, the decimal point won't matter much?post:ask.metafilter.com,2007:site.64927Sat, 16 Jun 2007 15:58:29 -0800.kobayashi.baseballresolvedBy: Steven C. Den Beste

It's just a typographic convention. I think you're reading too much into it.comment:ask.metafilter.com,2007:site.64927-976730Sat, 16 Jun 2007 16:00:55 -0800Steven C. Den BesteBy: dw

Because it's a space-saving box score abbreviation. 7.1 means 7 1/3; it just saves two characters of space.comment:ask.metafilter.com,2007:site.64927-976732Sat, 16 Jun 2007 16:02:16 -0800dwBy: dw

And Elias and others in the stat biz don't use 7.1 to calculate ERA; they use 7.333....comment:ask.metafilter.com,2007:site.64927-976733Sat, 16 Jun 2007 16:03:32 -0800dwBy: jerseygirl

SCDB is right. 7.1 means "7 and one-third"; you'll never see a pitcher with 7.8 IP or other such nonsense, provided you're using a reputable source. ERA is also calculated using thirds of an inning. I assume the reason for .1 and .2 is that it would have been a pain for newspapers to typeset the 1/3 and 2/3 characters in box scores.comment:ask.metafilter.com,2007:site.64927-976735Sat, 16 Jun 2007 16:04:25 -0800SuperNovaBy: SuperNova

Others use .3 and .7, e.g. here's <a href="http://www.baseball-reference.com/h/hernafe02.shtml">King Felix's baseballreference page</a>. It's still calculated as .333 and .667.comment:ask.metafilter.com,2007:site.64927-976737Sat, 16 Jun 2007 16:06:25 -0800dwBy: spira

In print, it isn't really space-saving, but more readable. I'm one of the editors of the ESPN Baseball Encyclopedia, and we could certainly fit 1/3 or 2/3 in the space we put .1 or .2, but given that our type is already quite small, the fractions would be virtually unreadable.<br>
<br>
The problem with .3 and .7 is that no one could ever agree on whether the latter should be .6 or .7.comment:ask.metafilter.com,2007:site.64927-976742Sat, 16 Jun 2007 16:23:19 -0800spiraBy: holgate

The same convention applies for <a href="http://content-aus.cricinfo.com/engvwi/engine/match/258462.html">bowling figures in cricket</a>: .1 for each ball of a six-ball over. It's less fiddly than typesetting fractions and less confusing than trying to resolve decimals.comment:ask.metafilter.com,2007:site.64927-976789Sat, 16 Jun 2007 18:54:20 -0800holgateBy: misterbrandt

So it's really just a Base 3 notation...comment:ask.metafilter.com,2007:site.64927-977083Sun, 17 Jun 2007 10:09:31 -0800misterbrandt
