ABS — the Automated Ball-Strike System

5 pitches went to the robots · 4 overturned (ump overruled) · 1 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.

  1. 1James McCann — ump said strike, robot ruled ball: overturned.
  2. 2Geraldo Perdomo — ump said ball, robot ruled strike: overturned.
  3. 3Fernando Tatis Jr. — ump said ball, robot ruled strike: overturned.
  4. 4James McCann — ump said strike, robot ruled ball: overturned.
  5. 5Luis Campusano — ump said ball, robot ruled ball: upheld.

Our tracked-rulebook zone matched the ABS ruling on 2 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
