Home plate: Derek Thomas
“Solid and unspectacular — exactly what the job asks.”
What this shows — how Derek Thomas called the 141 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 134 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

Jackson Chourio vs Shota Imanaga - 3-0.13▲5 · 1-1 ball called strike
Sal Frelick vs Ethan Roberts
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
3 pitches went to the robots · 2 overturned (ump overruled) · 1 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Carson Kelly — ump said ball, robot ruled ball: upheld.
- 2William Contreras — ump said ball, robot ruled strike: overturned.
- 3Carson Kelly — ump said ball, robot ruled strike: overturned.
Our tracked-rulebook zone matched the ABS ruling on 2 of 3 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
