What this shows — how Brock Ballou called the 152 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.

The zone, as he called it

Challenge 1: Bryson Stott — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled).1Challenge 2: Adrian Del Castillo — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).2

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

2 pitches went to the robots · 2 overturned (ump overruled) · 0 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.

  1. 1Bryson Stott — ump said ball, robot ruled strike: overturned.
  2. 2Adrian Del Castillo — ump said strike, robot ruled ball: overturned.

Our tracked-rulebook zone matched the ABS ruling on 0 of 2 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
