What this shows — how Tom Hanahan called the 187 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 177 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 · 4 overturned (ump overruled) · 1 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1JJ Bleday — ump said strike, robot ruled strike: upheld.
- 2Carson Kelly — ump said ball, robot ruled strike: overturned.
- 3Michael Busch — ump said strike, robot ruled ball: overturned.
- 4Carson Kelly — ump said ball, robot ruled strike: overturned.
- 5Tyler Stephenson — ump said ball, robot ruled strike: overturned.
Our tracked-rulebook zone matched the ABS ruling on 3 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
