DIPS and BABIP
Matt gives us his take.
I’d like to point out two things:
1. SolvingDIPS (pdf) has gotten to similar conclusions in terms of the split between pitching and fielding as it relates to BABIP.
2. The conversion from BABIP to runs is usually ignored in these DIPS talks. A GB pitcher gives up more hits, but fewer % of extrabase hits, but also gets more DP. Overall, and you may find this hard to believe, in terms of RUNS per batted ball in play, GB and FB are the same! (Excludes Pops, Liners, HR.)
So, even if you find a BABIP skill, it’s irrelevant to know that. What we really want is his RUNS skill on batted balls.
And in that case, Voros’s initial claim is much more realistic.
