BABIP and xBABIP (cont)

After I posted that, I got to wondering how players batting averages would change if they were exactly meeting their xBABIP. Rather than go back and edit the original post, here it is. The first four data columns are from the google doc spreadsheet reference in the last post. The next is each batter's current batting average. The last one, which I labeled xAVG, is what they would be hitting based on xBABIP.

Why is Dominguez's xAVG < AVG when his xBABIP > BIBIP? Think you miscalculated

The Batguy said...

Good catch; two mistakes.

#1. Dominguez' actual BABIP was a typo. Should be .256, not .246.

#2. Didn't account for Sac Flies for anyone

Entire table has been updated.

Thanks for doing this, it's interesting stuff... unfortunately for the Astros, the "fair" results would still be pretty pitiful for basically all the regulars but Altuve.

I'm immediately struck by the Speed Score for George Springer. I'm expect that to increase to around a 5 as he gets more opportunity to show his speed.

The Batguy said...

Yeah, The Constable and I discussed that exact thing offline. Springer's speed is what has allowed him to beat out his swinging bunts so far.
