What this shows — how Dan Merzel called the 182 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 175 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: Drake Baldwin — the ump called it a ball, the robot ruled ball (upheld — ump confirmed).1Challenge 2: Matt Olson — the ump called it a strike, the robot ruled strike (upheld — ump confirmed).2Challenge 3: Rodolfo Durán — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).3

  3. 3+0.13▼2 · 1-0 strike called ball

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

3 pitches went to the robots · 1 overturned (ump overruled) · 2 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.

  1. 1Drake Baldwin — ump said ball, robot ruled ball: upheld.
  2. 2Matt Olson — ump said strike, robot ruled strike: upheld.
  3. 3Rodolfo Durán — ump said strike, robot ruled ball: overturned.

Our tracked-rulebook zone matched the ABS ruling on 2 of 3 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
