ABS — the Automated Ball-Strike System

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

  1. 1Brian Serven — ump said strike, robot ruled ball: overturned.
  2. 2Victor Caratini — ump said strike, robot ruled ball: overturned.
  3. 3Victor Caratini — ump said strike, robot ruled ball: overturned.
  4. 4Luke Keaschall — ump said ball, robot ruled strike: overturned.
  5. 5Victor Caratini — ump said ball, robot ruled ball: upheld.
  6. 6Brian Serven — ump said strike, robot ruled ball: overturned.
  7. 7Ryan Kreidler — ump said ball, robot ruled strike: overturned.
  8. 8Ryan Jeffers — ump said strike, robot ruled strike: upheld.

Our tracked-rulebook zone matched the ABS ruling on 2 of 8 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
