What this shows — how Clint Vondrak called the 171 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 160 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: Jake Burger — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled).1Challenge 2: Corey Seager — 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 Hawkeye ground truth, no model involved.

  1. 1Jake Burger — ump said ball, robot ruled strike: overturned.
  2. 2Corey Seager — 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.
