Home plate: Alan Porter
“The kind of night where the umpire is the least of the story.”
What this shows — how Alan Porter called the 172 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 164 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
2 pitches went to the robots · 1 overturned (ump overruled) · 1 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Willi Castro — ump said strike, robot ruled strike: upheld.
- 2Hunter Goodman — ump said ball, robot ruled strike: overturned.
Our tracked-rulebook zone matched the ABS ruling on 2 of 2 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
