What this shows — how Shane Livensparger called the 139 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 124 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

4 pitches went to the robots · 3 overturned (ump overruled) · 1 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Luis Torrens — ump said ball, robot ruled strike: overturned.
  2. 2Carson Benge — ump said strike, robot ruled ball: overturned.
  3. 3Luis Torrens — ump said ball, robot ruled ball: upheld.
  4. 4Samuel Basallo — ump said ball, robot ruled strike: overturned.

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