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

2 pitches went to the robots · 0 overturned (ump overruled) · 2 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.

  1. 1William Contreras — ump said ball, robot ruled ball: upheld.
  2. 2William Contreras — ump said ball, robot ruled ball: upheld.

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