What this shows — how Alan Porter called the 176 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 170 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 Hawkeye ground truth, no model involved.

  1. 1Ryan O'Hearn — ump said strike, robot ruled strike: upheld.
  2. 2Bubba Chandler — ump said strike, robot ruled ball: overturned.
  3. 3Carson Kelly — ump said strike, robot ruled ball: overturned.
  4. 4Carson Kelly — ump said strike, robot ruled ball: overturned.
  5. 5Joey Bart — ump said strike, robot ruled strike: upheld.
  6. 6Alex Bregman — ump said strike, robot ruled strike: upheld.

Our tracked-rulebook zone matched the ABS ruling on 3 of 6 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
