ABS — the Automated Ball-Strike System

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

  1. 1Connor Wong — ump said strike, robot ruled ball: overturned.
  2. 2Wade Meckler — ump said strike, robot ruled strike: upheld.
  3. 3Willson Contreras — ump said strike, robot ruled strike: upheld.
  4. 4Caleb Durbin — ump said ball, robot ruled strike: overturned.

Our tracked-rulebook zone matched the ABS ruling on 3 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
