What this shows — how Quinn Wolcott called the 160 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 145 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

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

6 pitches went to the robots · 4 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1TJ Rumfield — ump said strike, robot ruled ball: overturned.
  2. 2Edouard Julien — ump said strike, robot ruled ball: overturned.
  3. 3Hunter Goodman — ump said ball, robot ruled strike: overturned.
  4. 4Joe Mack — ump said ball, robot ruled ball: upheld.
  5. 5Brian Navarreto — ump said ball, robot ruled strike: overturned.
  6. 6Edouard Julien — ump said strike, robot ruled strike: upheld.

Our tracked-rulebook zone matched the ABS ruling on 6 of 6 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
