ABS — the Automated Ball-Strike System
3 pitches went to the robots · 2 overturned (ump overruled) · 1 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Patrick Bailey — ump said ball, robot ruled ball: upheld.
- 2Geraldo Perdomo — ump said strike, robot ruled ball: overturned.
- 3Patrick Bailey — ump said ball, robot ruled strike: overturned.
Our tracked-rulebook zone matched the ABS ruling on 2 of 3 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
