What this shows — how Dan Iassogna called the 132 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 116 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

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

  1. 1Carlos Narváez — ump said strike, robot ruled ball: overturned.
  2. 2Carlos Narváez — ump said ball, robot ruled ball: upheld.
  3. 3Tyler Stephenson — ump said ball, robot ruled strike: overturned.
  4. 4Roman Anthony — ump said ball, robot ruled strike: overturned.

Our tracked-rulebook zone matched the ABS ruling on 2 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
