What this shows — how Tom Hanahan called the 120 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 105 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

ABS — the Automated Ball-Strike System

4 pitches went to the robots · 4 overturned (ump overruled) · 0 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Ryan O'Hearn — ump said strike, robot ruled ball: overturned.
  2. 2Ryan O'Hearn — ump said strike, robot ruled ball: overturned.
  3. 3William Contreras — ump said ball, robot ruled strike: overturned.
  4. 4Henry Davis — 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), not our error.
