- 2Brett Sullivan — ump said ball, robot ruled ball: upheld.
- 3Brett Sullivan — ump said ball, robot ruled strike: overturned.
- 4Brett Sullivan — 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.
