What this shows — how Edwin Moscoso called the 110 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 100 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 · 4 overturned (ump overruled) · 0 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Christian Vázquez — ump said ball, robot ruled strike: overturned.
  2. 2Isaac Paredes — ump said strike, robot ruled ball: overturned.
  3. 3Raynel Delgado — ump said strike, robot ruled ball: overturned.
  4. 4Stuart Fairchild — ump said strike, robot ruled ball: overturned.

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