What this shows — how Adam Hamari called the 160 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 151 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

2 pitches went to the robots · 2 overturned (ump overruled) · 0 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Christian Walker — ump said ball, robot ruled strike: overturned.
  2. 2Wyatt Langford — ump said ball, robot ruled strike: 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.
