What this shows — how Alfonso Márquez called the 140 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 126 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

7 pitches went to the robots · 6 overturned (ump overruled) · 1 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Dillon Dingler — ump said ball, robot ruled strike: overturned.
  2. 2Dillon Dingler — ump said ball, robot ruled strike: overturned.
  3. 3Jasson Domínguez — ump said strike, robot ruled ball: overturned.
  4. 4Dillon Dingler — ump said ball, robot ruled strike: overturned.
  5. 5Austin Wells — ump said strike, robot ruled ball: overturned.
  6. 6Austin Wells — ump said ball, robot ruled strike: overturned.
  7. 7Oswaldo Cabrera — ump said strike, robot ruled strike: upheld.

Our tracked-rulebook zone matched the ABS ruling on 7 of 7 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
