ABS — the Automated Ball-Strike System

6 pitches went to the robots · 4 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Christian Vázquez — ump said strike, robot ruled ball: overturned.
  2. 2Christian Vázquez — ump said strike, robot ruled ball: overturned.
  3. 3LaMonte Wade Jr. — ump said strike, robot ruled strike: upheld.
  4. 4Christian Vázquez — ump said strike, robot ruled strike: upheld.
  5. 5Esteury Ruiz — ump said ball, robot ruled strike: overturned.
  6. 6Joe Mack — ump said ball, robot ruled strike: overturned.

Our tracked-rulebook zone matched the ABS ruling on 2 of 6 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
