Hope this is the right place for this question. I've Googled it several times and haven't found a good explanation. Can someone explain to me how a batting average against a particular pitch is calculated?
That stat (for example, "he's batting 0.XXX vs sliders and only 0.YYY vs changeups") is thrown around a lot but it doesn't seem to be very straightforward or a reliable stat at all. Given that batting average is hits / at bats and each at bat is made up of multiple pitches, I can't see looking at a result from one pitch from a given at bat being put in a way we can gain anything from it.
Can anyone explain this for me? I think just knowing the calculation may clear up my issue with it.
