“The zone leaned, and the ledger noticed.”
What this shows — how Derek Thomas called the 150 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 141 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
3 pitches went to the robots · 1 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Pete Crow-Armstrong — ump said strike, robot ruled strike: upheld.
- 2Dillon Dingler — ump said strike, robot ruled ball: overturned.
- 3Dillon Dingler — ump said ball, robot ruled ball: upheld.
Our tracked-rulebook zone matched the ABS ruling on 1 of 3 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
