What this shows — how Hunter Wendelstedt called the 189 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 174 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

5 pitches went to the robots · 2 overturned (ump overruled) · 3 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Tyler Stephenson — ump said strike, robot ruled ball: overturned.
  2. 2Tyler Stephenson — ump said ball, robot ruled ball: upheld.
  3. 3JJ Bleday — ump said ball, robot ruled strike: overturned.
  4. 4Jimmy Crooks — ump said ball, robot ruled ball: upheld.
  5. 5Pedro Pagés — ump said ball, robot ruled ball: upheld.

Our tracked-rulebook zone matched the ABS ruling on 1 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
