ABS — the Automated Ball-Strike System
4 pitches went to the robots · 3 overturned (ump overruled) · 1 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

- 2Iván Herrera — ump said strike, robot ruled ball: overturned.
- 3Xander Bogaerts — ump said strike, robot ruled strike: upheld.
- 4Iván Herrera — ump said ball, robot ruled strike: overturned.
Our tracked-rulebook zone matched the ABS ruling on 3 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
