What this shows — how James Hoye called the 193 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. 178 were right. Below, only the misses are plotted, alongside every challenged pitch.

ABS — the Automated Ball-Strike System

8 pitches went to the robots · 5 overturned (ump overruled) · 3 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Alec Burleson — ump said strike, robot ruled strike: upheld.
  2. 2Andrew Knizner — ump said ball, robot ruled strike: overturned.
  3. 3Iván Herrera — ump said ball, robot ruled strike: overturned.
  4. 4Jonah Cox — ump said strike, robot ruled ball: overturned.
  5. 5Joshua Báez — ump said strike, robot ruled strike: upheld.
  6. 6Drew Cavanaugh — ump said strike, robot ruled ball: overturned.
  7. 7Drew Cavanaugh — ump said ball, robot ruled ball: upheld.
  8. 8César Prieto — ump said strike, robot ruled ball: overturned.

Our tracked-rulebook zone matched the ABS ruling on 8 of 8 — a zone-definition gap (ABS grades a standardized, height-based zone). Where the two disagree, the umpire is graded on the ABS ruling.
