  2. 2Dillon Dingler — ump said ball, robot ruled strike: overturned.
  3. 3Spencer Torkelson — ump said strike, robot ruled ball: overturned.
  4. 4Steven Kwan — ump said strike, robot ruled ball: overturned.

Our tracked-rulebook zone matched the ABS ruling on 8 of 8 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
