What this shows — how Dan Merzel called the 136 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 128 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: Evan Carter — the ump called it a strike, the robot ruled strike (upheld — ump confirmed).1Challenge 2: Danny Jansen — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).2Challenge 3: Joey Bart — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).3Challenge 4: Konnor Griffin — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled).4

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

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

  1. 1Evan Carter — ump said strike, robot ruled strike: upheld.
  2. 2Danny Jansen — ump said strike, robot ruled ball: overturned.
  3. 3Joey Bart — ump said strike, robot ruled ball: overturned.
  4. 4Konnor Griffin — ump said ball, robot ruled strike: overturned.

Our tracked-rulebook zone matched the ABS ruling on 2 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
