What this shows — how Adrian Johnson called the 116 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 106 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

Run impact from the count run-value table: a missed strike three is worth far more than one on 3-0.

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. 1Jorge Mateo — ump said ball, robot ruled strike: overturned.
  2. 2Freddy Peralta — ump said strike, robot ruled ball: overturned.
  3. 3Colt Keith — ump said ball, robot ruled strike: overturned.
  4. 4Liam Hicks — ump said strike, robot ruled ball: overturned.
  5. 5Brett Callahan — ump said strike, robot ruled strike: upheld.
  6. 6Nick Fortes — ump said ball, robot ruled ball: upheld.

Our tracked-rulebook zone matched the ABS ruling on 3 of 6 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
