What this shows — how Shane Livensparger 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: Sean Burke — the ump called it a ball, the robot ruled ball (upheld — ump confirmed).1Challenge 2: Yainer Diaz — the ump called it a strike, the robot ruled strike (upheld — ump confirmed).2Challenge 3: Edgar Quero — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).3

ABS — the Automated Ball-Strike System

3 pitches went to the robots · 1 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Sean Burke — ump said ball, robot ruled ball: upheld.
  2. 2Yainer Diaz — ump said strike, robot ruled strike: upheld.
  3. 3Edgar Quero — ump said strike, robot ruled ball: overturned.

Our tracked-rulebook zone matched the ABS ruling on 2 of 3 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
