What this shows — how Louie Krupa called the 158 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 148 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: Elias Díaz — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).1

The calls that moved the game

  1. 1-0.286 · 1-2 ball called strike
    Buddy Kennedy vs Tyler Alexander
  2. 2-0.207 · 2-1 ball called strike
    Ezequiel Duran vs Jason Foley
  3. 3+0.131 · 1-0 strike called ball
    Willy Adames vs Cody Bradford

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

1 pitch went to the robots · 1 overturned (ump overruled) · 0 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Elias Díaz — ump said strike, robot ruled ball: overturned.

Our tracked-rulebook zone matched the ABS ruling on 0 of 1 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
