What this shows — how Bill Miller called the 158 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 152 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: Gabriel Moreno — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).1Challenge 2: Geraldo Perdomo — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled).2Challenge 3: Masyn Winn — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled).3Challenge 4: Jimmy Crooks — the ump called it a ball, the robot ruled ball (upheld — ump confirmed).4Challenge 5: Ketel Marte — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled).5Challenge 6: Geraldo Perdomo — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled).6

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

6 pitches went to the robots · 5 overturned (ump overruled) · 1 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.

  1. 1Gabriel Moreno — ump said strike, robot ruled ball: overturned.
  2. 2Geraldo Perdomo — ump said ball, robot ruled strike: overturned.
  3. 3Masyn Winn — ump said ball, robot ruled strike: overturned.
  4. 4Jimmy Crooks — ump said ball, robot ruled ball: upheld.
  5. 5Ketel Marte — ump said ball, robot ruled strike: overturned.
  6. 6Geraldo Perdomo — ump said ball, robot ruled strike: overturned.

Our tracked-rulebook zone matched the ABS ruling on 1 of 6 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
