ABS — the Automated Ball-Strike System

7 pitches went to the robots · 6 overturned (ump overruled) · 1 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Patrick Bailey — ump said ball, robot ruled strike: overturned.
  2. 2Patrick Bailey — ump said ball, robot ruled strike: overturned.
  3. 3Brayan Rocchio — ump said strike, robot ruled ball: overturned.
  4. 4Rhys Hoskins — ump said strike, robot ruled ball: overturned.
  5. 5Patrick Bailey — ump said ball, robot ruled strike: overturned.
  6. 6Patrick Bailey — ump said ball, robot ruled ball: upheld.
  7. 7Patrick Bailey — ump said ball, robot ruled strike: overturned.

Our tracked-rulebook zone matched the ABS ruling on 5 of 7 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
