  2. 2Spencer Horwitz — ump said strike, robot ruled strike: upheld.
  3. 3Moisés Ballesteros — ump said ball, robot ruled strike: overturned.
  4. 4Henry Davis — ump said ball, robot ruled strike: overturned.
  5. 5Tyler Heineman — ump said ball, robot ruled ball: upheld.
  6. 6Mike Trout — ump said strike, robot ruled ball: overturned.
  7. 7Henry Davis — ump said ball, robot ruled ball: upheld.
  8. 8Travis d'Arnaud — ump said strike, robot ruled strike: upheld.

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.
