Two are measures of the top and the bottom of the strike zone (sz_bot and sz_top), values that reflect the size of the zone once adjusted for batter height and stance. Finally, we use the resulting call of the pitch. In conjunction, these 5 values can tell us whether a pitch was a strike or a ball, and whether or not it was called correctly.

I’m an avid board game player, of the heavy euro strategy variety. They often employ a technique wherein all the tiles/areas of the game are split into “hexes.” These work exceptionally well at dividing up an arbitrary area into even spaces, as opposed to square grids, which can have very sharp edges. We’ll employ this technique today to visualize ...
This model assumed the vertical center of the zone was at 2.5 feet. Future research will modify this to be variable based on the batter’s height. Ideally, our formula stated above should include the batter’s height as a variable to get a more accurate zone. For now, this is currently a blind spot.
Umpires are fallible; they’re human, after all. Accurately calling a ball or strike along one axis is really hard. When two axes are involved, this become exponentially more difficult. This is why the corners of the strike zone are more accurately described by circles, and the interior edges are more accurately described by a gently sloping arc tha...

Feb 5, 2020 · Achieving consistency while calling balls and strikes starts with the definition of the strike zone. In NFHS, USA and USSSA, it is the space over home plate between the batter’s armpit and the top of the knees when the batter assumes a natural batting stance. The NCAA specifies the bottom of the batter’s sternum instead of the armpit.
