ABS — the Automated Ball-Strike System

8 pitches went to the robots · 5 overturned (ump overruled) · 3 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Jakob Marsee — ump said ball, robot ruled strike: overturned.
  2. 2Agustín Ramírez — ump said strike, robot ruled ball: overturned.
  3. 3Rafael Flores Jr. — ump said strike, robot ruled ball: overturned.
  4. 4Leo Jiménez — ump said strike, robot ruled strike: upheld.
  5. 5Agustín Ramírez — ump said strike, robot ruled ball: overturned.
  6. 6Agustín Ramírez — ump said ball, robot ruled ball: upheld.
  7. 7Nick Gonzales — ump said ball, robot ruled strike: overturned.
  8. 8Spencer Horwitz — ump said strike, robot ruled strike: upheld.

Our tracked-rulebook zone matched the ABS ruling on 3 of 8 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
