What this shows — how Tripp Gibson called the 132 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 128 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: Pete Alonso — the ump called it a strike, the robot ruled strike (upheld — ump confirmed).1Challenge 2: Willson Contreras — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled).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. 1Pete Alonso — ump said strike, robot ruled strike: upheld.
  2. 2Willson Contreras — ump said ball, robot ruled strike: overturned.

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.
