ABS — the Automated Ball-Strike System

5 pitches went to the robots · 3 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Kyle Tucker — ump said strike, robot ruled ball: overturned.
  2. 2Carlos Narváez — ump said ball, robot ruled strike: overturned.
  3. 3Ceddanne Rafaela — ump said strike, robot ruled strike: upheld.
  4. 4Eliezer Alfonzo — ump said ball, robot ruled ball: upheld.
  5. 5Caleb Durbin — ump said strike, robot ruled ball: overturned.

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