What this shows — how Mike Estabrook called the 127 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 120 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

7 pitches went to the robots · 6 overturned (ump overruled) · 1 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1James McCann — ump said ball, robot ruled strike: overturned.
  2. 2Jonah Heim — ump said ball, robot ruled strike: overturned.
  3. 3Michael Harris II — ump said strike, robot ruled ball: overturned.
  4. 4James McCann — ump said ball, robot ruled strike: overturned.
  5. 5Jonah Heim — ump said ball, robot ruled strike: overturned.
  6. 6Gabriel Moreno — ump said strike, robot ruled ball: overturned.
  7. 7Mauricio Dubón — ump said strike, robot ruled strike: upheld.

Our tracked-rulebook zone matched the ABS ruling on 7 of 7 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
