ABS — the Automated Ball-Strike System

3 pitches went to the robots · 3 overturned (ump overruled) · 0 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Nick Kurtz — ump said strike, robot ruled ball: overturned.
  2. 2Shea Langeliers — ump said ball, robot ruled strike: overturned.
  3. 3Austin Wynns — ump said ball, robot ruled strike: overturned.

Our tracked-rulebook zone matched the ABS ruling on 2 of 3 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
