What this shows — how David Rackley called the 136 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 128 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: Patrick Bailey — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).1Challenge 2: Mark Vientos — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled).2Challenge 3: Patrick Bailey — the ump called it a ball, the robot ruled ball (upheld — ump confirmed).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. 1Patrick Bailey — ump said strike, robot ruled ball: overturned.
  2. 2Mark Vientos — ump said ball, robot ruled strike: overturned.
  3. 3Patrick Bailey — ump said ball, robot ruled ball: upheld.

Our tracked-rulebook zone matched the ABS ruling on 1 of 3 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
