Pitch-level linear weights

One of my current sabermetric obsessions is pitch sequencing. It’s a huge topic, and to try and dent it ever so slightly I have found it useful to be able to assign run values to every major event in every count. In other words: pitch-level linear weights.

Ed Sheehan wrote about this in 2008. I used a similar methodology and updated the results for the bulk of the PITCHf/x era.

Good luck, and happy analyzing.
