PAP is basically worthless. Cubing the difference between the number of pitches thrown (after reaching 100) and 100 is ridiculous. That's saying it is 27 times worse to throw 115 pitches than it is to throw 105 pitches. Ridiculous. I'm not saying that you can't determine pitcher abuse with statistics, but if you are not looking at the right numbers, you're basically wasting your time. Factors that need to be considered when determining pitcher abuse: total pitches thrown (worthless if used by itself), pitches thrown per inning, pitches thrown per K and per BB, wild pitches, velocity changes over an inning/game, gameday temperature and weather, etc. There is no way PAP is anything more than a thrown together stat that people accepted just b/c there are a few injury prone guys at the top of the list. Prior and Wood are abused, but that comes more from the distribution of their pitches over the course of the game rather than the total number of pitches they throw. Throwing (pitches by inning) 35, 15, 15, 15, 10, 15 and throwing 10,10,10,15,10,15,10,15,10 both have the same PAP. What do you think is worse on a pitchers' arm?
