What the latest Statcast upgrade makes possible

But let’s talk about something far more interesting than that. Let’s talk about what’s become known as pose tracking, a new phrase that’s about to become extremely important.

With the old gear, players were, for lack of a better term, blobs. Their position was measured in terms of where their center of mass was, but that was about it. There was no indication of arms or legs, no real way to track explicit movements, arm motions or swing paths. That was fine, for what it was; it was, after all, the first time anyone had been able to track player movement at all in real time. It was incredibly useful to track starting depth, ending positions, different types of defensive shifts, running speed, strongest catcher throwing arms and so on.

But it was limiting, too, for all the reasons you could imagine. Did this first baseman do a better job of stretching for a throw than that one? No idea. Did a batter in a slump have a subtle change to his swing mechanics? We’d have loved to have known. Such are the limitations of blobs.

With pose tracking now an option, those kinds of questions—and more—are now potentially answerable. You can see what that means in the example picture below. See those green lines? They’re arms, legs and everything else that makes a player look like a human—and that opens all sorts of new doors.
