  2. 2Drew Cavanaugh — ump said ball, robot ruled ball: upheld.
  3. 3Randy Arozarena — ump said strike, robot ruled strike: upheld.
  4. 4Cal Raleigh — ump said strike, robot ruled ball: overturned.
  5. 5Cal Raleigh — ump said ball, robot ruled strike: overturned.

Our tracked-rulebook zone matched the ABS ruling on 4 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
