ABS — the Automated Ball-Strike System

7 pitches went to the robots · 6 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. 2Jonah Heim — ump said strike, robot ruled ball: overturned.
  3. 3Michael Harris II — ump said ball, robot ruled strike: overturned.
  4. 4James McCann — ump said strike, robot ruled ball: overturned.
  5. 5Jonah Heim — ump said strike, robot ruled ball: overturned.
  6. 6Gabriel Moreno — ump said ball, robot ruled strike: overturned.
  7. 7Mauricio Dubón — ump said strike, robot ruled strike: upheld.

Our tracked-rulebook zone matched the ABS ruling on 1 of 7 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
