What this shows — how John Libka called the 139 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 131 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: Dominic Smith — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled).1Challenge 2: Miguel Amaya — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).2

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

2 pitches went to the robots · 2 overturned (ump overruled) · 0 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.

  1. 1Dominic Smith — ump said ball, robot ruled strike: overturned.
  2. 2Miguel Amaya — ump said strike, robot ruled ball: overturned.

Our tracked-rulebook zone matched the ABS ruling on 0 of 2 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
