I am reading Jon Bales mlb book and it’s got me thinking about BvP. I understand that typically there is not enough data to use BvP as a predictive measure, but have there been studies or are there tools that can be used to look at batters versus an aggregate of certain types of pitchers? I know that pitchers are typically aggregated by handedness, but what I am looking for is a subset of those pitchers. For example, is there a tool we can use to look at how Anthony Rizzo fares against righties whose fastball is 91-93 and whose primary out pitch is a slider or something along those lines?
Edit: Thinking about this a little more, can we aggregate fangraphs pitchfx data to create pitcher groups, and then analyze hitters against those groups?
