What this shows — how Mike Estabrook called the 117 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 110 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: Carlos Narváez — the ump called it a ball, the robot ruled ball (upheld — ump confirmed).1Challenge 2: Ben Williamson — the ump called it a strike, the robot ruled strike (upheld — ump confirmed).2

The calls that moved the game

  1. 1+0.287 · 1-2 strike called ball
    Tsung-Che Cheng vs Chris Roycroft
  2. 2-0.138 · 1-0 ball called strike
    Anthony Seigler vs Ben Williamson
  3. 3-0.138 · 1-0 ball called strike
    Masataka Yoshida vs Ben Williamson

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 · 0 overturned (ump overruled) · 2 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.

  1. 1Carlos Narváez — ump said ball, robot ruled ball: upheld.
  2. 2Ben Williamson — ump said strike, robot ruled strike: upheld.

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