What this shows — how James Jean called the 188 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 175 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

5 pitches went to the robots · 2 overturned (ump overruled) · 3 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.

  1. 1Rodolfo Durán — ump said ball, robot ruled ball: upheld.
  2. 2Jonah Heim — ump said strike, robot ruled ball: overturned.
  3. 3Mark Leiter Jr. — ump said ball, robot ruled ball: upheld.
  4. 4Jackson Merrill — ump said ball, robot ruled strike: overturned.
  5. 5Hogan Harris — ump said ball, robot ruled ball: upheld.

Our tracked-rulebook zone matched the ABS ruling on 4 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
