ABS — Automated Ball-Strike System
3 pitches challenged · 1 overturned (umpire overruled) · 2 upheld (umpire confirmed). This is Hawkeye ground truth on the calls, not a model.
Our tracked-rulebook zone matched the ABS ruling on 2 of 3 — a zone-definition gap (the ABS zone differs from the rulebook zone), not our accuracy.
