The zone, as he called it

The calls that moved the game

  1. 1+0.207 · 2-1 strike called ball
    Ceddanne Rafaela vs Kyle Finnegan
  2. 2+0.133 · 1-0 strike called ball
    Hao-Yu Lee vs Ranger Suarez
  3. 3+0.1310 · 1-0 strike called ball
    Spencer Torkelson vs Garrett Whitlock

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

  1. 1Connor Wong — ump said ball, robot ruled ball: upheld.

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.
