What this shows — how Dan Iassogna called the 180 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 165 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

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

  1. 1Angel Martínez — ump said ball, robot ruled strike: overturned.
  2. 2Austin Hedges — ump said strike, robot ruled ball: overturned.
  3. 3Kyle Manzardo — ump said ball, robot ruled strike: overturned.
  4. 4Carter Jensen — ump said ball, robot ruled ball: upheld.

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.
