What this shows — how John Libka called the 133 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 129 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

Challenge 1: Austin Wells — the ump called it a ball, the robot ruled ball (upheld — ump confirmed).1Challenge 2: José Caballero — the ump called it a strike, the robot ruled strike (upheld — ump confirmed).2Challenge 3: Ryan Watson — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).3

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

3 pitches went to the robots · 1 overturned (ump overruled) · 2 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.

  1. 1Austin Wells — ump said ball, robot ruled ball: upheld.
  2. 2José Caballero — ump said strike, robot ruled strike: upheld.
  3. 3Ryan Watson — ump said strike, robot ruled ball: overturned.

Our tracked-rulebook zone matched the ABS ruling on 2 of 3 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
