Baseball Stat Acronyms Pronunciation Guide


As the title describes, we'll get right to it. There's some discussion regarding what's the right and wrong way to pronounce particular baseball acronyms, so let's put it to rest.

First, there are three different types of pronunciation styles.

1. Worders. These are typically abbreviations instead of acronyms. For this, you are required to say the entire word for which it stands. AVG and SLG fall into this category.

2. Sounders. These are acronyms which spell an easy-to-pronounce word. For this, best practice is to sound it out and hope you got it right. WAR and FIP are perfect examples. wOBA is up for debate, since its non-weighted little brother belongs to the next category.

3. Spellers. These are acronyms for which one would sound stupid sounding it out but take too long to word it out. Just say the letters you see and you'll get along just fine. ERA, OBP, OBA and other similar ones belong here.

After the jump, find a list of common baseball and saber stats and exactly how you should pronounce them.

 

Star-divide

AVG - Worder. "Average." If using BA, that's a speller.

OBP - Speller. "oh-bee-pee." Sometimes a worder when shortened conversationally to "on base."

SLG - Worder. "Slugging." Don't try anything else with this one.

OPS - Speller. "oh-pee-ess." Don't be the goofball talking about "psy-OPS" or "black-OPS."

ISO - Sounder. "eye-soh," as it's short for "Isolated Slugging." If you're spelling it out (eye-ess-oh), what do those letters stand for? (nothing!)

wOBA - Sounder. "whoa-bah." It's simply too long to spell out. Or if you insist, wake me up when you're done wording it out.

BABIP - Speller. You gotta spell this one out, fellas. Sorry. "Bee-ay-bee-eye-pee." Sound it out at your own risk.

*% - This is a trick one, where * = anything like "BB," "K" or "SB." You typically will be required to say the entire word of the *, while saying "rate" intead of "percent," while the latter is still socially acceptable.

wRC and variants - Worder. If you're using this you're probably doing a little heavy lifting anyway, so just word this one out. "Runs Created based wOBA."

FIP - Sounder. "fip." Rhymes with "rip."

ERA - Speller. "eee-arrr-aay." If you see a +, just say "plus."

WAR - Sounder. "war." Rhymes with "bore" or "core," not "car" or "bar."

UZR - Speller. Nobody wants to hear you say "uhhh-zerr" so just spell it out. "You-Zee-Arr."

RAR - Sounder. Probably as goofy as "whoa-bah," "raaawr" is still better than stumbling through "R-A-R."

 

Btw (that's a worder, btw), I'm from Kansas City where we have little other claim to fame than being the general guide for national broadcaster's dialectical and inflection style. This is my only qualification for putting this together. Feel free to debate what should and should not be sounded out, but be prepared to be wrong. Enjoy!

In general, I avoid spelling out multi-syllabic letters like “double-u.” “Weighted” is a touch easier. Just a touch, but still.

While I don’t vocalize them often, in my thoughts they’re either spelled out or said in their entirety.

You may be an northern/easterner,

and you probably can’t be blamed. I mean, is the US currently in the Iraq “Waaaahr” or the Iraq “Wore?” Unless you’re from Boston, where neither matters. “Yeah Bonds has like da second highest waah of all time.”

The latter is probably most appropriate, though I can’t blame your heritage if you’re from Boston.

nope, chicagoan

but I guess we have our own way of pronouncing things too

by Barold on Mar 2, 2011 6:39 PM EST up reply actions  

I just thought it made sense

to say it as in the word “war” because it’s intuitive to assume that an abbreviation that spells out an already existing word would be pronounced like that word. Maybe that’s just me, though, because for a long time my favorite defensive stat was “you-zer.”

Then again, I don’t really have anyone to talk about saber stuff in person with, so these issues haven’t come up for me much unless I’m talking to myself.

Spelling it out is just ugly. If you don’t drag out the first syllable you’ll be fine saying it.

Also, if wOBA is too long to spell, then you have to make BABIP a sounder.

BABIP

Even though its the wrong spelling, I always felt BABIP sounded better as “BA-PIP”. Its much easier that way.

Exactly.

Sky points that out below and I updated the OP to make that point.

by Justin Bopp on Mar 3, 2011 1:46 PM EST up reply actions  

I actually disagree on quite a few of these

I just can’t behind saying ISO phonetically; for me, it has to be eye-ess-oh.
I prefer double-yoo-oh-bee-ay over whoa-ba, but I’m somewhat on the fence about that one.
wRC+, to me, should be double-yoo-ar-see-plus, and similarly for related statistics.
I’m in the surprisingly large minority of people who find it strange to pronounce FIP. (Ex-)eff-eye-pee sounds much nicer to me.
You’re absolutely in the minority who thinks that WAR should sound like the word and not rhyme with car.

Many of my preferred pronunciations are corroborated by the comments on a FanGraphs post some time ago with just this subject, although I don’t pretend to have any qualifications beyond that. I do know that I’m in the minority on FIP and xFIP, but I refuse to budge for some reason, and I’m not alone by any stretch.

I agree on spelling FIP and ISO

But I’m surprised that people would pronounce WAR like “car” and not “war”. I’ve very little opportunity to talk about these stats with my voice instead of typing, but I’ve got to think that if WAR went mainstream it would be pronounced like “war”.

by brogshan on Mar 3, 2011 8:37 AM EST up reply actions  

I'll post this again here because it's still relevant

Isn’t ISO just short for “Isolated?” Isn’t it an abbreviation and not an acronym? If so it should either be a worder or a sounder.

by J-Doug on Mar 3, 2011 1:46 PM EST up reply actions  

Yes, that's an excellent point

Now that you’ve brought that up, I can’t justify spelling it, but old habits die hard. “Eye-so,” similar as it is to “eye-ess-oh,” just doesn’t end up “sounding right” to me because I’ve been mentally pronouncing it by spelling it for as long as I’ve known of the statistic.

Question about fielding stats

SABER novice here. My understanding is that RAR stands for “Run Above Replacement,” but whenever I’m reading a fielding analysis, writers seem to describe a player’s RAR rating as “so many runs above (or below) average.” This is confusing, especially since it seems that RAR (at least on fangraphs, which I use regularly to look up stats) is a component of a player’s WAR rating, which measures against replacement level.

Does 0RAR indicate a replacement level fielder or an average fielder? Sorry if this is a dumb question.

by SuckaMD on Mar 2, 2011 11:12 PM EST reply actions  

Not a dumb question

Yes, when we’re talking fielding, replacement level is also average. But not when we’re talking pitching or hitting.

Blogger and Editor, Rational Pastime Blog. Twitter: @RationalPastime.

by J-Doug on Mar 3, 2011 2:50 AM EST up reply actions  

thanks for that

one more question: on what basis is an average fielder assumed to be replacement level? Is it really that easy (in theory) to find an average fielding CF on the scrap heap?

by SuckaMD on Mar 3, 2011 8:59 AM EST up reply actions  

Yes

Tom Tango has done the most work on that, but you basically try to identify replacement level by seeing which cutoff point makes the cost-to-win conversion linear. It just happens to work out that replacement level for fielders is also average level.

FIP spelled out does sound kinda silly, but I think “fip” sounds sillier. EFF-EYE-PEE will sometimes get confused with “if I pee” which is just funny to me.

Albert Pujols does not have "down" years. He has "~6 WAR" years.

by mattybobo on Mar 3, 2011 10:29 AM EST up reply actions  

Jon Miller has also started saying “awps” (OPS) during Giants’ broadcasts. I was actually hoping this one would be addressed in the original post, but no dice. So, here comes my two cents.

OPS is a speller, particularly since it appears so commonly as OPS+. “Awps plus” just sounds unintelligible to me.

The real question, is OPS a sounder, worder, or speller?

I’ve always sounded it like black “ops”. But it seems that I’ve known people who do all three.

I beg to differ...

I pronounce a number of these differently than above:

wOBA – spelling, for me. “double-u-oh-bee-ay” It’s an abbreviation, so this works. The alternative,“wohba” , just sounds silly.

wRC – spelling, for me. “double-u-ar-see”.

WAR – This rhymes with “car” for me. Otherwise, you’re talking about something happening in Afganistan or Libya. And why would you have WAR and RAR not rhyme?
 
BABIP -sounder, for me, “ba-bip” the first syllable rhymes with “tab” and the second with “sip”.

What about...

BB/9 = Worder? “Walks per nine” or “Walk rate.”
K/9 = Worder? I’ve mostly heard “Whiff rate.”
K/BB = ?
HR/9 = ?
HR/FB = ???

by PioneerSkies on Mar 3, 2011 12:43 PM EST reply actions  

*/9 = * “per nine”

“Whiff Rate” is K% and “Walk Rate” BB%.

If you see an acronym on both sides of the /, you have to approach them individually, but usually just apply the pronuciation for each side and then append ‘ratio’ to the end. For example:

K/BB is “kay to walk ratio” or “strikeouts to walks ratio”
HR/FB is “homer to flyball ratio” or “homerun-flyball ratio”

Fantastic question.

by Justin Bopp on Mar 3, 2011 1:05 PM EST up reply actions   1 recs

I consider "whiff rate," at least for pitchers as SwStr%.

Which means that I call K% K-rate, as it confuses me to have two whiff rates.

Also, K/BB is “K-BB ratio”.

by ThePanda on Mar 6, 2011 12:40 PM EST up reply actions  

All rates/ratios that are written as rates/ratios should be worders

This isn’t just a sabr thing, this is a universal thing. km/h is pronounced kilometers per hour, for instance.
