ABS — the Automated Ball-Strike System

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

  1. 1Taylor Trammell — ump said ball, robot ruled strike: overturned.
  2. 2Yainer Diaz — ump said ball, robot ruled ball: upheld.
  3. 3James Outman — ump said ball, robot ruled strike: overturned.
  4. 4Christian Walker — ump said strike, robot ruled strike: upheld.
  5. 5Dillon Dingler — ump said strike, robot ruled ball: overturned.
  6. 6Yainer Diaz — ump said ball, robot ruled ball: upheld.

Our tracked-rulebook zone matched the ABS ruling on 3 of 6 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
