What this shows — how Austin Jones called the 127 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 118 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: Luis Torrens — the ump called it a ball, the robot ruled ball (upheld — ump confirmed).1

The calls that moved the game

  1. 1+0.136 · 1-1 strike called ball
    Chandler Simpson vs Nate Lavender
  2. 2-0.135 · 1-0 ball called strike
    Taylor Walls vs Robert Stock
  3. 3+0.108 · 0-1 strike called ball
    Taylor Walls vs Daniel Duarte

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

  1. 1Luis Torrens — ump said ball, robot ruled ball: upheld.

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