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

5 pitches went to the robots · 2 overturned (ump overruled) · 3 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.

  1. 1Sebastián Rivero — ump said strike, robot ruled ball: overturned.
  2. 2Jorge Soler — ump said ball, robot ruled strike: overturned.
  3. 3Austin Hedges — ump said ball, robot ruled ball: upheld.
  4. 4Angel Martínez — ump said strike, robot ruled strike: upheld.
  5. 5Mike Trout — ump said strike, robot ruled strike: upheld.

Our tracked-rulebook zone matched the ABS ruling on 4 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
