ABS — the Automated Ball-Strike System

3 pitches went to the robots · 0 overturned (ump overruled) · 3 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.

  1. 1Willson Contreras — ump said strike, robot ruled strike: upheld.
  2. 2Willson Contreras — ump said strike, robot ruled strike: upheld.
  3. 3Taylor Ward — ump said strike, robot ruled strike: upheld.

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