What this shows — how Clint Vondrak called the 153 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 142 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: Rafael Flores Jr. — the ump called it a strike, the robot ruled strike (upheld — ump confirmed).1

The calls that moved the game

  1. 1-0.698 · 3-2 ball called strike
    Brett Baty vs Mason Montgomery
  2. 2+0.282 · 1-2 strike called ball
    Esmerlyn Valdez vs Sean Manaea
  3. 3+0.238 · 0-2 strike called ball
    Ronny Simon vs Jack Weisenburger

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. 1Rafael Flores Jr. — ump said strike, robot ruled strike: 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.
