- 1Bryce Harper — ump said strike, robot ruled strike: upheld.
- 2J.T. Realmuto — ump said ball, robot ruled strike: overturned.
- 3Yainer Diaz — ump said ball, robot ruled strike: overturned.
- 4Yainer Diaz — ump said ball, robot ruled ball: upheld.
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.
