What this shows — how Jansen Visconti called the 149 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 139 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: Miguel Amaya — the ump called it a ball, the robot ruled ball (upheld — ump confirmed).1Challenge 2: Nico Hoerner — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled).2Challenge 3: Dansby Swanson — the ump called it a strike, the robot ruled strike (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 Hawkeye ground truth, no model involved.

  1. 1Miguel Amaya — ump said ball, robot ruled ball: upheld.
  2. 2Nico Hoerner — ump said ball, robot ruled strike: overturned.
  3. 3Dansby Swanson — ump said strike, robot ruled strike: upheld.

Our tracked-rulebook zone matched the ABS ruling on 1 of 3 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
