What this shows — how Alfonso Márquez called the 148 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 136 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

Run impact from the count run-value table: a missed strike three is worth far more than one on 3-0.

ABS — the Automated Ball-Strike System

5 pitches went to the robots · 3 overturned (ump overruled) · 2 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.

  1. 1Cal Raleigh — ump said strike, robot ruled ball: overturned.
  2. 2Austin Wynns — ump said strike, robot ruled ball: overturned.
  3. 3Cal Raleigh — ump said ball, robot ruled ball: upheld.
  4. 4Cal Raleigh — ump said strike, robot ruled ball: overturned.
  5. 5Lawrence Butler — ump said strike, robot ruled strike: upheld.

Our tracked-rulebook zone matched the ABS ruling on 1 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
