ABS — the Automated Ball-Strike System
4 pitches went to the robots · 1 overturned (ump overruled) · 3 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.
- 1Jose Altuve — ump said strike, robot ruled strike: upheld.
- 2Nolan Schanuel — ump said strike, robot ruled strike: upheld.
- 3Cam Smith — ump said strike, robot ruled strike: upheld.
- 4Mike Trout — ump said strike, robot ruled ball: overturned.
Our tracked-rulebook zone matched the ABS ruling on 4 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
