“To be clear, what we have here is not a full and complete data set, at least in the same way it is for the Majors. For Triple-A, it includes all of 2023, as well as Pacific Coast League games and Charlotte home games in 2022. For Single-A, it dates back to 2021, but only for the eight Statcast-enabled Florida State League parks. There’s not any Double-A at all included at this time. Still, that’s nearly two million pitches, regular and postseason, and that’s more than enough to draw some broad conclusions.
So: What have we learned? Let’s share some big takeaways. (Unless otherwise noted, all comparisons here will be across 2021-23, regular and postseason combined.)”
