What this shows — how Hunter Wendelstedt called the 152 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 142 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 · 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. 1Garrett Stubbs — ump said ball, robot ruled strike: overturned.
  2. 2Seiya Suzuki — ump said strike, robot ruled ball: overturned.
  3. 3Kyle Schwarber — ump said strike, robot ruled strike: upheld.
  4. 4Carson Kelly — ump said ball, robot ruled strike: overturned.
  5. 5Trea Turner — ump said strike, robot ruled ball: overturned.
  6. 6Michael Busch — ump said strike, robot ruled strike: upheld.

Our tracked-rulebook zone matched the ABS ruling on 5 of 6 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
