Benchmarks: Updates on Chase and Watch
Posted by Harry PavlidisIn short, I'll probably dispose of "Watch" and just stick with swing rates in three regions. As suggested by Tango and others, I've broken pitch locations down into three groups:
- In Tight Zone (ITZ)
- Paint, Knees or Letters (PKL)
- Outside Wide Zone (OWZ)
The zones are based on player height with a sprinkle of PITCHf/x operator data. It's based on work Mike Fast has been doing, which I'll gladly steal. I'll have more in the follow-up benchmarks article, but don't expect great detail on those zone definitions.
I'm still in pilot mode, so take a grain of salt -- but here are the swing rates in each of the three regions even though their definitions are subject to change.
ITZ PKL OWZ .559 .451 .369
I wonder if I need to tighten up the ITZ. Thoughts?

This is really intriguing, but I’m confused. The PKL zone would refer to pitches that were actually in the strike zone, correct? And what qualifies for the “tight zone”?
