What this shows — how D.J. Reyburn called the 117 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. 108 were right. Below, only the misses are plotted, alongside every challenged pitch.

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. 1Lawrence Butler — ump said strike, robot ruled strike: upheld.
  2. 2Weston Wilson — ump said strike, robot ruled strike: upheld.
  3. 3Jhonny Pereda — ump said ball, robot ruled strike: overturned.
  4. 4Jhonny Pereda — ump said ball, robot ruled strike: overturned.

Our tracked-rulebook zone matched the ABS ruling on 4 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.
