What this shows — how Alex MacKay called the 159 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 153 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: Joe Mack — the ump called it a ball, the robot ruled ball (upheld — ump confirmed).1Challenge 2: Samuel Basallo — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled).2

The calls that moved the game

  1. 1+0.69▼1 · 3-2 strike called ball
    Connor Norby vs Brandon Young
  2. 2+0.13▲6 · 1-0 strike called ball
    Dylan Beavers vs Dax Fulton
  3. 3-0.09▼1 · 0-0 ball called strike
    Xavier Edwards vs Brandon Young

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. 1Joe Mack — ump said ball, robot ruled ball: upheld.
  2. 2Samuel Basallo — 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.
