What this shows — how Ron Kulpa called the 166 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 154 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

The zone, as he called it

Challenge 1: Connor Wong — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).1Challenge 2: Connor Wong — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled).2Challenge 3: Alejandro Kirk — the ump called it a ball, the robot ruled ball (upheld — ump confirmed).3Challenge 4: Ceddanne Rafaela — the ump called it a strike, the robot ruled strike (upheld — ump confirmed).4Challenge 5: Wilyer Abreu — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled).5

Run impact from the count run-value table: a missed strike three is worth far more than one on 3-0.

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. 1Connor Wong — ump said strike, robot ruled ball: overturned.
  2. 2Connor Wong — ump said ball, robot ruled strike: overturned.
  3. 3Alejandro Kirk — ump said ball, robot ruled ball: upheld.
  4. 4Ceddanne Rafaela — ump said strike, robot ruled strike: upheld.
  5. 5Wilyer Abreu — 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.
