Run impact from the count run-value table: a missed strike three is worth far more than one on 3-0.

ABS — the Automated Ball-Strike System

3 pitches went to the robots · 1 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Jordan Beck — ump said strike, robot ruled strike: upheld.
  2. 2Brett Sullivan — ump said strike, robot ruled ball: overturned.
  3. 3Zac Veen — ump said strike, robot ruled strike: upheld.

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.
