What this shows — how Ryan Additon called the 145 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 136 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: Brian Serven — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).1Challenge 2: Henry Bolte — 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 the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Brian Serven — ump said strike, robot ruled ball: overturned.
  2. 2Henry Bolte — ump said strike, robot ruled strike: upheld.

Our tracked-rulebook zone matched the ABS ruling on 1 of 2 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
