What this shows — how Dan Iassogna called the 172 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 161 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

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

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

  1. 1Nick Kurtz — ump said ball, robot ruled strike: overturned.
  2. 2José Caballero — ump said ball, robot ruled strike: overturned.
  3. 3Aaron Judge — ump said strike, robot ruled strike: upheld.
  4. 4Jazz Chisholm Jr. — ump said strike, robot ruled strike: upheld.
  5. 5Shea Langeliers — ump said ball, robot ruled ball: upheld.
  6. 6Jeff McNeil — ump said ball, robot ruled strike: overturned.

Our tracked-rulebook zone matched the ABS ruling on 3 of 6 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
