What this shows — how Todd Tichenor called the 142 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 129 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

6 pitches went to the robots · 4 overturned (ump overruled) · 2 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 strike: upheld.
  2. 2Cole Carrigg — ump said strike, robot ruled ball: overturned.
  3. 3Brett Sullivan — ump said ball, robot ruled strike: overturned.
  4. 4Spencer Horwitz — ump said strike, robot ruled strike: upheld.
  5. 5Willi Castro — ump said strike, robot ruled ball: overturned.
  6. 6Braxton Fulford — ump said strike, robot ruled ball: overturned.

Our tracked-rulebook zone matched the ABS ruling on 5 of 6 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
