What this shows — how Alex MacKay called the 121 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 116 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

ABS — the Automated Ball-Strike System

4 pitches went to the robots · 2 overturned (ump overruled) · 2 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.

  1. 1Manny Machado — ump said strike, robot ruled strike: upheld.
  2. 2TJ Rumfield — ump said strike, robot ruled strike: upheld.
  3. 3Hunter Goodman — ump said strike, robot ruled ball: overturned.
  4. 4Hunter Goodman — ump said strike, robot ruled ball: overturned.

Our tracked-rulebook zone matched the ABS ruling on 2 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
