What this shows — how Alex MacKay called the 161 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 155 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

6 pitches went to the robots · 3 overturned (ump overruled) · 3 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Riley Greene — ump said strike, robot ruled ball: overturned.
  2. 2Shea Langeliers — ump said ball, robot ruled ball: upheld.
  3. 3Shea Langeliers — ump said ball, robot ruled strike: overturned.
  4. 4Henry Bolte — ump said strike, robot ruled ball: overturned.
  5. 5Kevin McGonigle — ump said strike, robot ruled strike: upheld.
  6. 6Zack Gelof — ump said strike, robot ruled strike: upheld.

Our tracked-rulebook zone matched the ABS ruling on 5 of 6 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
