What this shows — how Quinn Wolcott called the 125 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 117 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

ABS — the Automated Ball-Strike System

6 pitches went to the robots · 5 overturned (ump overruled) · 1 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Alejandro Kirk — ump said strike, robot ruled strike: upheld.
  2. 2Carlos Narváez — ump said strike, robot ruled ball: overturned.
  3. 3Carlos Narváez — ump said strike, robot ruled ball: overturned.
  4. 4Jarren Duran — ump said ball, robot ruled strike: overturned.
  5. 5Alejandro Kirk — ump said strike, robot ruled ball: overturned.
  6. 6Alejandro Kirk — ump said strike, robot ruled ball: overturned.

Our tracked-rulebook zone matched the ABS ruling on 1 of 6 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
