ABS — the Automated Ball-Strike System

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

  1. 1Matt Wallner — ump said ball, robot ruled strike: overturned.
  2. 2Josh Bell — ump said ball, robot ruled strike: overturned.
  3. 3Samuel Basallo — ump said strike, robot ruled strike: upheld.
  4. 4Ryan Jeffers — ump said ball, robot ruled ball: upheld.
  5. 5Ryan Jeffers — ump said ball, robot ruled strike: overturned.

Our tracked-rulebook zone matched the ABS ruling on 2 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
