What this shows — how Adam Hamari called the 170 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 161 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: Coby Mayo — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled).1Challenge 2: Tyler Heineman — the ump called it a ball, the robot ruled ball (upheld — ump confirmed).2Challenge 3: Tyler Heineman — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).3Challenge 4: Tyler Heineman — the ump called it a ball, the robot ruled ball (upheld — ump confirmed).4

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

4 pitches went to the robots · 2 overturned (ump overruled) · 2 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.

  1. 1Coby Mayo — ump said ball, robot ruled strike: overturned.
  2. 2Tyler Heineman — ump said ball, robot ruled ball: upheld.
  3. 3Tyler Heineman — ump said strike, robot ruled ball: overturned.
  4. 4Tyler Heineman — ump said ball, robot ruled ball: upheld.

Our tracked-rulebook zone matched the ABS ruling on 2 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
