What this shows — how Chad Fairchild called the 150 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 138 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

The zone, as he called it

The calls that moved the game

  1. 1+0.234 · 0-2 strike called ball
    Roman Anthony vs Andre Pallante
  2. 2-0.196 · 2-0 ball called strike
    Caleb Durbin vs George Soriano
  3. 3+0.196 · 2-0 strike called ball
    Iván Herrera vs Brayan Bello

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

1 pitch went to the robots · 1 overturned (ump overruled) · 0 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.

  1. 1Alec Burleson — ump said ball, robot ruled strike: overturned.

Our tracked-rulebook zone matched the ABS ruling on 0 of 1 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
