What this shows — how Alex MacKay called the 158 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 148 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

ABS — the Automated Ball-Strike System

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

  1. 1Joe Mack — ump said strike, robot ruled ball: overturned.
  2. 2Richard Lovelady — ump said strike, robot ruled ball: overturned.
  3. 3Drew Millas — ump said ball, robot ruled ball: upheld.
  4. 4Drew Millas — ump said ball, robot ruled ball: upheld.
  5. 5Joe Mack — ump said strike, robot ruled ball: overturned.
  6. 6Owen Caissie — ump said ball, robot ruled strike: overturned.

Our tracked-rulebook zone matched the ABS ruling on 0 of 6 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
