What this shows — how Hunter Wendelstedt called the 129 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 120 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

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. 1Cal Raleigh — ump said ball, robot ruled strike: overturned.
  2. 2Spencer Horwitz — ump said strike, robot ruled ball: overturned.
  3. 3Ryan O'Hearn — ump said strike, robot ruled ball: overturned.
  4. 4Marcell Ozuna — ump said strike, robot ruled ball: overturned.
  5. 5Endy Rodríguez — ump said ball, robot ruled ball: upheld.
  6. 6Cal Raleigh — ump said ball, robot ruled ball: 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.
