What this shows — how Mike Muchlinski called the 153 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.

ABS — the Automated Ball-Strike System

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

  1. 1Josh Naylor — ump said strike, robot ruled strike: upheld.
  2. 2Sam Antonacci — ump said ball, robot ruled strike: overturned.
  3. 3Randy Arozarena — ump said strike, robot ruled strike: upheld.
  4. 4Jarred Kelenic — ump said strike, robot ruled strike: upheld.
  5. 5Drew Romo — ump said strike, robot ruled ball: overturned.
  6. 6Munetaka Murakami — ump said strike, robot ruled strike: upheld.

Our tracked-rulebook zone matched the ABS ruling on 4 of 6 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
