ABS — the Automated Ball-Strike System

6 pitches went to the robots · 4 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Ronald Acuña Jr. — ump said strike, robot ruled ball: overturned.
  2. 2Drake Baldwin — ump said ball, robot ruled strike: overturned.
  3. 3Jakob Marsee — ump said strike, robot ruled ball: overturned.
  4. 4Agustín Ramírez — ump said ball, robot ruled strike: overturned.
  5. 5Drake Baldwin — ump said ball, robot ruled ball: upheld.
  6. 6Michael Harris II — ump said strike, robot ruled strike: upheld.

Our tracked-rulebook zone matched the ABS ruling on 4 of 6 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
