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. 1Ethan Salas — ump said ball, robot ruled strike: overturned.
  2. 2Ethan Salas — ump said ball, robot ruled strike: overturned.
  3. 3Joe Mack — ump said ball, robot ruled strike: overturned.
  4. 4Heriberto Hernández — ump said strike, robot ruled strike: upheld.
  5. 5Joe Mack — ump said ball, robot ruled strike: overturned.
  6. 6Fernando Tatis Jr. — ump said strike, robot ruled strike: upheld.
  7. 7Ethan Salas — ump said ball, robot ruled ball: upheld.
  8. 8Brian Navarreto — ump said ball, robot ruled strike: overturned.

Our tracked-rulebook zone matched the ABS ruling on 6 of 8 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
