Home plate: Adam Hamari
“A clean sheet behind the plate — the kind of night nobody posts about.”
What this shows — how Adam Hamari called the 118 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 113 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.
The zone, as he called it

Run impact from the count run-value table: a missed strike three is worth far more than one on 3-0.
ABS — the Automated Ball-Strike System
1 pitch went to the robots · 1 overturned (ump overruled) · 0 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Matt Vierling — ump said strike, robot ruled ball: overturned.
Our tracked-rulebook zone matched the ABS ruling on 0 of 1 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
