What this shows — how Mark Wegner called the 174 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 158 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

ABS — the Automated Ball-Strike System

7 pitches went to the robots · 3 overturned (ump overruled) · 4 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Jonah Cox — ump said strike, robot ruled ball: overturned.
  2. 2Andrew Knizner — ump said ball, robot ruled strike: overturned.
  3. 3Andrew Knizner — ump said ball, robot ruled ball: upheld.
  4. 4Andrew Knizner — ump said ball, robot ruled ball: upheld.
  5. 5Leo Bernal — ump said strike, robot ruled strike: upheld.
  6. 6Bryan Torres — ump said strike, robot ruled ball: overturned.
  7. 7Andrew Knizner — ump said ball, robot ruled ball: upheld.

Our tracked-rulebook zone matched the ABS ruling on 7 of 7 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
