What this shows — how John Libka called the 179 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 173 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

The zone, as he called it

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 · 2 overturned (ump overruled) · 4 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Otto Lopez — ump said strike, robot ruled strike: upheld.
  2. 2Jose Trevino — ump said ball, robot ruled ball: upheld.
  3. 3Brian Navarreto — ump said strike, robot ruled ball: overturned.
  4. 4JJ Bleday — ump said ball, robot ruled strike: overturned.
  5. 5Brian Navarreto — ump said ball, robot ruled ball: upheld.
  6. 6Jose Trevino — ump said ball, robot ruled ball: upheld.

Our tracked-rulebook zone matched the ABS ruling on 4 of 6 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
