-- edited to add this note: I should have read the entire post before responding. -- I've got to be honest - since this isn't something I'm concerned about, I'm not willing to do the research here. But if I were going to see if I could pick something up in the data, I'd do something along the following lines... Any persistent pattern for the entire team that was due to a philosophy for the team or instruction for the coach should be measurable, if it is significant enough to matter. I believe this would show up when they either swing at pitches outside the zone or if they are laying off pitches in the zone (they are guessing on a particular pitch and get fooled) I'd first look to see where the team ranks in those measurements overall Then I would look to see where they rank in those metrics when ahead in the count and also when behind in the count to see if they are guessing in particular situations To try to find some trend, I'd look for extreme differences in behavior in the overall, early in the count and late in the count results There are a ton of problems with the analysis. First, it is really heavily influenced by the types of hitters we have in the first place. Second, when you start dividing the results by count, it becomes really hard to tell if what you're seeing is just noise or if there is evidence of a real change in approach. Third, it is really difficult to tell if there is a "problem" with the approach or if the problem lies in the execution. But if I were really interested, I'd take a look at those stats just to see if anything jumped out at me.
