What this shows — how Alex MacKay called the 139 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.

The zone, as he called it

Run impact from the count run-value table: a missed strike three is worth far more than one on 3-0.

ABS — the Automated Ball-Strike System

4 pitches went to the robots · 3 overturned (ump overruled) · 1 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.

  1. 1Austin Wells — ump said strike, robot ruled ball: overturned.
  2. 2Dillon Dingler — ump said strike, robot ruled ball: overturned.
  3. 3Dillon Dingler — ump said ball, robot ruled ball: upheld.
  4. 4Dillon Dingler — ump said strike, robot ruled ball: overturned.

Our tracked-rulebook zone matched the ABS ruling on 1 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
