What this shows — how Alex MacKay called the 189 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 182 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 · 1 overturned (ump overruled) · 3 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.

  1. 1Vinnie Pasquantino — ump said ball, robot ruled strike: overturned.
  2. 2Travis d'Arnaud — ump said ball, robot ruled ball: upheld.
  3. 3Carter Jensen — ump said ball, robot ruled ball: upheld.
  4. 4Bryce Teodosio — ump said strike, robot ruled strike: upheld.

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.
