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.
- 1Lawrence Butler — ump said ball, robot ruled strike: overturned.
- 2Donovan Walton — ump said ball, robot ruled strike: overturned.
- 3Jonah Heim — ump said ball, robot ruled ball: upheld.
Our tracked-rulebook zone matched the ABS ruling on 1 of 3 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
