What this shows — how Cory Blaser called the 137 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 130 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: Freddy Fermin — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).1Challenge 2: Iván Herrera — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).2Challenge 3: Victor Scott II — the ump called it a ball, the robot ruled strike (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 · 3 overturned (ump overruled) · 0 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.

  1. 1Freddy Fermin — ump said strike, robot ruled ball: overturned.
  2. 2Iván Herrera — ump said strike, robot ruled ball: overturned.
  3. 3Victor Scott II — ump said ball, robot ruled strike: 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.
