ABS — the Automated Ball-Strike System

4 pitches went to the robots · 4 overturned (ump overruled) · 0 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Kyle Karros — ump said strike, robot ruled ball: overturned.
  2. 2Cal Raleigh — ump said ball, robot ruled strike: overturned.
  3. 3Hunter Goodman — ump said ball, robot ruled strike: overturned.
  4. 4Cal Raleigh — ump said ball, robot ruled strike: overturned.

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