What this shows — how Mark Ripperger called the 151 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 144 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: Freddy Fermin — the ump called it a ball, the robot ruled ball (upheld — ump confirmed).1Challenge 2: Freddy Fermin — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).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. 1Freddy Fermin — ump said ball, robot ruled ball: upheld.
  2. 2Freddy Fermin — ump said strike, robot ruled ball: overturned.

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.
