What this shows — how Jansen Visconti called the 142 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 133 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

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

4 pitches went to the robots · 2 overturned (ump overruled) · 2 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.

  1. 1Nolan Gorman — ump said ball, robot ruled strike: overturned.
  2. 2Freddy Fermin — ump said ball, robot ruled ball: upheld.
  3. 3Masyn Winn — ump said ball, robot ruled strike: overturned.
  4. 4JJ Wetherholt — ump said strike, robot ruled strike: upheld.

Our tracked-rulebook zone matched the ABS ruling on 2 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
