ABS — the Automated Ball-Strike System

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

  1. 1William Contreras — ump said strike, robot ruled ball: overturned.
  2. 2Agustín Ramírez — ump said ball, robot ruled ball: upheld.
  3. 3Gary Sánchez — ump said strike, robot ruled strike: upheld.
  4. 4William Contreras — ump said ball, robot ruled ball: upheld.
  5. 5Connor Norby — ump said strike, robot ruled strike: upheld.
  6. 6William Contreras — ump said ball, robot ruled ball: upheld.

Our tracked-rulebook zone matched the ABS ruling on 4 of 6 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
