What this shows — how James Jean 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

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. 1Luis García Jr. — ump said strike, robot ruled ball: overturned.
  2. 2Joe Mack — ump said ball, robot ruled ball: upheld.
  3. 3James Wood — ump said strike, robot ruled strike: upheld.
  4. 4Joe Mack — ump said ball, robot ruled strike: overturned.
  5. 5Drew Millas — ump said ball, robot ruled strike: overturned.
  6. 6Otto Lopez — ump said strike, robot ruled ball: overturned.

Our tracked-rulebook zone matched the ABS ruling on 4 of 6 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
