ABS — the Automated Ball-Strike System

3 pitches went to the robots · 2 overturned (ump overruled) · 1 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.

  1. 1Gabriel Moreno — ump said strike, robot ruled ball: overturned.
  2. 2Corbin Carroll — ump said strike, robot ruled strike: upheld.
  3. 3Gabriel Moreno — ump said ball, robot ruled strike: overturned.

Our tracked-rulebook zone matched the ABS ruling on 0 of 3 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
