What this shows — how Mark Wegner called the 165 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 159 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: Myles Straw — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled).1Challenge 2: Daz Cameron — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled).2

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

2 pitches went to the robots · 2 overturned (ump overruled) · 0 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Myles Straw — ump said ball, robot ruled strike: overturned.
  2. 2Daz Cameron — ump said ball, robot ruled strike: overturned.

Our tracked-rulebook zone matched the ABS ruling on 1 of 2 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
