What this shows — how Adrian Johnson called the 143 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 131 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: Yainer Diaz — the ump called it a strike, the robot ruled strike (upheld — ump confirmed).1Challenge 2: Hao-Yu Lee — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled).2Challenge 3: Christian Walker — the ump called it a strike, the robot ruled strike (upheld — ump confirmed).3Challenge 4: Dillon Dingler — the ump called it a strike, the robot ruled ball (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 · 2 overturned (ump overruled) · 2 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.

  1. 1Yainer Diaz — ump said strike, robot ruled strike: upheld.
  2. 2Hao-Yu Lee — ump said ball, robot ruled strike: overturned.
  3. 3Christian Walker — ump said strike, robot ruled strike: upheld.
  4. 4Dillon Dingler — ump said strike, robot ruled ball: overturned.

Our tracked-rulebook zone matched the ABS ruling on 3 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
