League BABIP for hitting vs. League BABIP for pitching

+1 vote

My question is on BABIP. I noticed on fangraphs that this year the MLB-average BABIP for hitters is .297, yet the average BABIP for pitchers is .293

Why is that?

Here is the link for hitters: http://www.fangraphs.com/leaders.aspx?pos=all&stats=bat&lg=all&qual=0&type=8&season=2012&month=0&season1=2012&ind=0&team=0,ss&rost=0&age=0&filter=&players=0
Here is the link for pitchers: http://www.fangraphs.com/leaders.aspx?pos=all&stats=pit&lg=all&qual=0&type=2&season=2012&month=0&season1=2012&ind=0&team=0,ss&rost=0&age=0&filter=&players=0

Thank you kindly,
Ian

I'm not quite sure if I'm right, but I do know that in league wRC+ they incorporate wRC+ from when pitchers hit. It may be the same with BABIP, but then I'd imagine lgBABIP would be lower..

I was hoping the overseer would chime in on this one.

BABIP for pitchers includes SH because it's not something we keep track of for pitchers, while for batters we are able to remove it.

Formula for pitchers is : (H – HR) / (TBF – BB – HBP – HR – SO)

And the formula for batters is: (H - HR) / (AB - SO - HR + SF)

For pitchers we used to use the following and still do for years prior to 1916 where TBF data is not readily available: (H - HR) / (IP * 2.82 - SO - HR)

Should've known. For that very same reason I have to create my pitcher's BABIP formula in retrosheet then export/import it into my Lahman. I think this is what B-ref does?
