“An honest evening's grade: nothing loud, nothing missed by much.”
What this shows — how Tom Hanahan called the 179 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 172 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
5 pitches went to the robots · 2 overturned (ump overruled) · 3 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Isaac Collins — ump said strike, robot ruled strike: upheld.
- 2Eduardo Valencia — ump said ball, robot ruled ball: upheld.
- 3Kevin McGonigle — ump said strike, robot ruled ball: overturned.
- 4Eduardo Valencia — ump said ball, robot ruled ball: upheld.
- 5Carter Jensen — ump said ball, robot ruled strike: overturned.
Our tracked-rulebook zone matched the ABS ruling on 4 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
