What this shows — how Dexter Kelley called the 130 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 122 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. 1Willy Adames — ump said ball, robot ruled strike: overturned.
  2. 2Rafael Devers — ump said ball, robot ruled strike: overturned.
  3. 3Mitch Garver — ump said strike, robot ruled ball: overturned.
  4. 4Mitch Garver — ump said ball, robot ruled ball: upheld.

Our tracked-rulebook zone matched the ABS ruling on 3 of 4 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
