What this shows — how Hunter Wendelstedt called the 185 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 174 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

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. 1Drew Millas — ump said strike, robot ruled ball: overturned.
  2. 2Nasim Nuñez — ump said strike, robot ruled strike: upheld.
  3. 3Drew Millas — ump said strike, robot ruled ball: overturned.
  4. 4Jorbit Vivas — ump said strike, robot ruled strike: upheld.
  5. 5Caleb Durbin — ump said ball, robot ruled strike: overturned.
  6. 6Connor Wong — 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.
