What this shows — how Alfonso Márquez called the 125 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 116 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: Michael Harris II — the ump called it a strike, the robot ruled strike (upheld — ump confirmed).2

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

2 pitches went to the robots · 1 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. 2Michael Harris II — ump said strike, robot ruled strike: upheld.

Our tracked-rulebook zone matched the ABS ruling on 0 of 2 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
