ABS — the Automated Ball-Strike System

8 pitches went to the robots · 5 overturned (ump overruled) · 3 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1William Contreras — ump said ball, robot ruled strike: overturned.
  2. 2Jackson Chourio — ump said strike, robot ruled strike: upheld.
  3. 3William Contreras — ump said ball, robot ruled strike: overturned.
  4. 4Max Meyer — ump said ball, robot ruled ball: upheld.
  5. 5Javier Sanoja — ump said strike, robot ruled ball: overturned.
  6. 6Luis Lara — ump said strike, robot ruled ball: overturned.
  7. 7Joe Mack — ump said ball, robot ruled strike: overturned.
  8. 8Garrett Mitchell — ump said strike, robot ruled strike: upheld.

Our tracked-rulebook zone matched the ABS ruling on 7 of 8 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
