What this shows — how Brian O'Nora called the 153 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 135 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

3 pitches went to the robots · 0 overturned (ump overruled) · 3 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.

  1. 1Jonah Heim — ump said ball, robot ruled ball: upheld.
  2. 2Curtis Mead — ump said strike, robot ruled strike: upheld.
  3. 3Jonah Heim — ump said ball, robot ruled ball: upheld.

Our tracked-rulebook zone matched the ABS ruling on 2 of 3 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
