“Borderline went to the battery all night.”
What this shows — how Brian Walsh called the 121 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 109 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
4 pitches went to the robots · 1 overturned (ump overruled) · 3 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Michael Busch — ump said strike, robot ruled strike: upheld.
- 2Pete Crow-Armstrong — ump said strike, robot ruled ball: overturned.
- 3Miguel Amaya — ump said ball, robot ruled ball: upheld.
- 4Tyler Stephenson — ump said ball, robot ruled ball: upheld.
Our tracked-rulebook zone matched the ABS ruling on 3 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
