What this shows — how Nate Tomlinson called the 171 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 165 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: Samuel Basallo — the ump called it a ball, the robot ruled ball (upheld — ump confirmed).1Challenge 2: Leody Taveras — 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. 1Samuel Basallo — ump said ball, robot ruled ball: upheld.
  2. 2Leody Taveras — 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.
