What this shows — how Willie Traynor called the 197 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 185 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 · 2 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Gunnar Henderson — ump said strike, robot ruled strike: upheld.
  2. 2Coby Mayo — ump said strike, robot ruled strike: upheld.
  3. 3Reese McGuire — ump said ball, robot ruled strike: overturned.
  4. 4Reese McGuire — 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.
