ABS — the Automated Ball-Strike System
3 pitches went to the robots · 1 overturned (ump overruled) · 2 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.
- 1Francisco Alvarez — ump said strike, robot ruled ball: overturned.
- 2Patrick Bailey — ump said ball, robot ruled ball: upheld.
- 3Luis Arraez — ump said strike, robot ruled strike: upheld.
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.
