ABS — the Automated Ball-Strike System

6 pitches went to the robots · 4 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Jorge Mateo — ump said strike, robot ruled ball: overturned.
  2. 2Freddy Peralta — ump said ball, robot ruled strike: overturned.
  3. 3Colt Keith — ump said strike, robot ruled ball: overturned.
  4. 4Liam Hicks — ump said ball, robot ruled strike: overturned.
  5. 5Brett Callahan — ump said strike, robot ruled strike: upheld.
  6. 6Kenny Piper — ump said ball, robot ruled ball: upheld.

Our tracked-rulebook zone matched the ABS ruling on 5 of 6 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
