What this shows — how John Tumpane called the 95 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 91 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

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

  1. 1Patrick Bailey — ump said strike, robot ruled ball: overturned.
  2. 2Willson Contreras — ump said strike, robot ruled strike: upheld.
  3. 3Mickey Gasper — ump said strike, robot ruled ball: overturned.
  4. 4Patrick Bailey — ump said ball, robot ruled ball: upheld.
  5. 5Patrick Bailey — ump said strike, robot ruled ball: 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.
