ABS — the Automated Ball-Strike System

7 pitches went to the robots · 5 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Luis García Jr. — ump said strike, robot ruled strike: upheld.
  2. 2Nick Loftin — ump said strike, robot ruled ball: overturned.
  3. 3Keibert Ruiz — ump said ball, robot ruled strike: overturned.
  4. 4Carter Jensen — ump said ball, robot ruled strike: overturned.
  5. 5Jac Caglianone — ump said strike, robot ruled ball: overturned.
  6. 6Nasim Nuñez — ump said strike, robot ruled ball: overturned.
  7. 7Lane Thomas — ump said strike, robot ruled strike: upheld.

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.
