What this shows — how Cory Blaser called the 133 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 125 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: Dillon Dingler — the ump called it a ball, the robot ruled ball (upheld — ump confirmed).1Challenge 2: Wenceel Pérez — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled).2Challenge 3: Salvador Perez — 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. 1Dillon Dingler — ump said ball, robot ruled ball: upheld.
  2. 2Wenceel Pérez — ump said ball, robot ruled strike: overturned.
  3. 3Salvador Perez — ump said strike, robot ruled ball: overturned.

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.
