What this shows — how David Rackley called the 128 pitches that were taken (no swing), graded against the tracked rulebook strike zone, or, on a pitch the ABS (Automated Ball-Strike System) reviewed on a challenge, against its ruling. 115 were right. Below, only the misses are plotted, alongside every challenged pitch.

The zone, as he called it

Challenge 1: Drew Gilbert — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).1Challenge 2: Grant McCray — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).2Challenge 3: Luis Torrens — the ump called it a strike, the robot ruled strike (upheld — ump confirmed).3Challenge 4: Drew Cavanaugh — the ump called it a ball, the robot ruled ball (upheld — ump confirmed). Our tracking puts it on the other side of the line; the grade follows the ruling.4*

* Graded on the ABS ruling. ABS measures its own zone, set by the batter’s height and taken at the middle of the plate, and our tracking puts this pitch on the other side of the line.

Run impact from the count run-value table: a missed strike three is worth far more than one on 3-0.

ABS — the Automated Ball-Strike System

4 pitches went to the robots · 2 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Drew Gilbert — ump said strike, robot ruled ball: overturned.
  2. 2Grant McCray — ump said strike, robot ruled ball: overturned.
  3. 3Luis Torrens — ump said strike, robot ruled strike: upheld.
  4. 4Drew Cavanaugh — ump said ball, robot ruled ball: upheld.

Our tracked-rulebook zone matched the ABS ruling on 3 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone). Where the two disagree, the umpire is graded on the ABS ruling.
