Pitcher's batting average against

Big Train · 03-19-2003, 11:00 AM

I was wondering if there's either a site that has pitcher's stats for batting average against or a formula to calculate it?

Obviously it's hits/at-bats but the problem is figuring out exactly how many at- bats there were against a pitcher. I tried At-bats=Hits+Outs but my numbers were a little off then I remember ed that errors and a few other things count as at-bats.So I started just adding a few at-bats to account for these but all I can do is guess at the number.

Hmmm... a guess here....

at bats = #innings * 3 + #ER - #walks

#innings *3 is accounts for number of outs accounted for, double play or otherwise (where your forumla was off I believe)

#ER counted for batters that made base, not via error
then
Subtract # walks total to account for those on base not via hits

Hmm... something missing maybe.... ERs don't quite cut it, as with two out, an error made (allowing a runner on and inning to continue) --- any runs scored after that won't count as ERs, even if 4 consecutive batters get hits....

/ponders for a moment longer...

Huh? I'm confused what you mean. I don't se what earned runs have to do with batting averag and there is no reason to subtract walks since you aren't adding them in the 1st place.

An at-bat is either when a hitter gets a hit or makes an out or reaches base because of an error or something like a dropped third strike.

IP*3 will give you the number of outs add to that the number of hits, the problem is you're still missing the number of at-bats which resulted in errors. Another thing since a sacrifice hit counts as an out but not an at-bat that would throw it off a bit. Come to think of it double plays will also skew it because two outs are recorded as the result of one at-bat. Sorry if I'm missing something but I don't see how earned runs (or walks) have anything to do with it)

i'm not sure if there is a formula that can be taken from the "regular" statistics, but if there is, I'd like to know too.

I seriously doubt that you will be able to 100% firgure it out with out all the stats available. Sac flies and Sac bunts, Errors, hit batsmen and a few others i am sure are not counted too well for individual pitchers. I an not 100% sure but I think they would all have to be counted also,

At Bats = 3 * Innings pitched + hits allowed + reached on errors - sac hits allowed - sac flies allowed - double plays - pickoffs - caught stealing

That's the best you're gonna get

If you don't have a full dataset you can get a pretty good estimate using the following:

opponents' estimated AB = ((IP*3*.95)+H)

BA = (opponents' hits)/(opponents' estimated AB)

Simplified AB estimation: AB=IP*2.85+H

If you can find a good statistical book or service they often include BF (batters faced). Then it's simply subtracting the walks and hit batters and dividing the remaining ABs into the hits given up.

You also have to subtract sac hits, sac flies, and plays that resulted in errors.
