ABS — the Automated Ball-Strike System

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

  1. 1Christian Vázquez — ump said strike, robot ruled ball: overturned.
  2. 2Maikel Garcia — ump said strike, robot ruled strike: upheld.
  3. 3Jose Altuve — ump said ball, robot ruled strike: overturned.
  4. 4Carter Jensen — ump said ball, robot ruled ball: upheld.
  5. 5Christian Vázquez — ump said ball, robot ruled ball: upheld.
  6. 6Christian Walker — ump said ball, robot ruled strike: overturned.

Our tracked-rulebook zone matched the ABS ruling on 1 of 6 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
