Errors in both horizontal and vertical movement have never been higher in the four years that Statcast has made some of its data publicly available. So it’s not just your imagination as you watch the game on TV: In-broadcast representations of the strike zone (like FoxTrax) take their data from Statcast, and Statcast’s errors, in turn, have bred anger with umpires and confusion over how pitches are being called. The root cause of Statcast’s troubles is unknown.
