Home plate: Brian Walsh
“Solid and unspectacular — exactly what the job asks.”
What this shows — how Brian Walsh called the 156 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 147 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

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
5 pitches went to the robots · 3 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Andy Pages — ump said strike, robot ruled ball: overturned.
- 2Jung Hoo Lee — ump said strike, robot ruled ball: overturned.
- 3Eric Haase — ump said ball, robot ruled ball: upheld.
- 4Eric Haase — ump said ball, robot ruled strike: overturned.
- 5Teoscar Hernández — ump said strike, robot ruled strike: upheld.
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.
