What this shows — how Andy Fletcher called the 150 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 137 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

1 pitch went to the robots · 1 overturned (ump overruled) · 0 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

Our tracked-rulebook zone matched the ABS ruling on 1 of 1 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
