What this shows — how Brennan Miller called the 170 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 155 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: Gary Sánchez — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).1Challenge 2: Gary Sánchez — the ump called it a ball, the robot ruled ball (upheld — ump confirmed).2Challenge 3: Carlos Narváez — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).3

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 Hawkeye ground truth, no model involved.

  1. 1Gary Sánchez — ump said strike, robot ruled ball: overturned.
  2. 2Gary Sánchez — ump said ball, robot ruled ball: upheld.
  3. 3Carlos Narváez — ump said strike, robot ruled ball: overturned.

Our tracked-rulebook zone matched the ABS ruling on 0 of 3 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
