Home plate: Brock Ballou
“A workmanlike night — nothing to frame, nothing to fix.”
What this shows — how Brock Ballou called the 152 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 145 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
2 pitches went to the robots · 2 overturned (ump overruled) · 0 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Bryson Stott — ump said strike, robot ruled ball: overturned.
- 2Adrian Del Castillo — ump said ball, robot ruled strike: overturned.
Our tracked-rulebook zone matched the ABS ruling on 2 of 2 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
