  1. 1Junior Caminero — ump said strike, robot ruled ball: overturned.
  2. 2Chandler Simpson — ump said strike, robot ruled strike: upheld.
  3. 3Nick Fortes — ump said ball, robot ruled strike: overturned.
  4. 4Nick Fortes — ump said strike, robot ruled strike: upheld.
  5. 5Wyatt Langford — ump said strike, robot ruled strike: upheld.
  6. 6Elias Díaz — ump said ball, robot ruled strike: overturned.
  7. 7Elias Díaz — ump said ball, robot ruled strike: overturned.

Our tracked-rulebook zone matched the ABS ruling on 7 of 7 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
