ABS — the Automated Ball-Strike System
2 pitches went to the robots · 2 overturned (ump overruled) · 0 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Tyler Heineman — ump said strike, robot ruled ball: overturned.
- 2Elias Díaz — ump said strike, robot ruled ball: overturned.
Our tracked-rulebook zone matched the ABS ruling on 0 of 2 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
