What this shows — how Jansen Visconti called the 145 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

Challenge 1: Will Smith — the ump called it a ball, the robot ruled ball (upheld — ump confirmed).1Challenge 2: James McCann — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled).2Challenge 3: Edwin Díaz — the ump called it a ball, the robot ruled ball (upheld — ump confirmed).3

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

3 pitches went to the robots · 1 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Will Smith — ump said ball, robot ruled ball: upheld.
  2. 2James McCann — ump said ball, robot ruled strike: overturned.
  3. 3Edwin Díaz — ump said ball, robot ruled ball: upheld.

Our tracked-rulebook zone matched the ABS ruling on 2 of 3 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
