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

1 pitch went to the robots · 1 overturned (ump overruled) · 0 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.

Our tracked-rulebook zone matched the ABS ruling on 0 of 1 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
