Home plate: Alan Porter
“Down the middle. Both dugouts had the same zone.”
What this shows — how Alan Porter called the 120 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 111 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
6 pitches went to the robots · 3 overturned (ump overruled) · 3 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Mauricio Dubón — ump said strike, robot ruled ball: overturned.

Our tracked-rulebook zone matched the ABS ruling on 6 of 6 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
