What this shows — how Roberto Ortiz called the 192 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.

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

5 pitches went to the robots · 3 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Iván Herrera — ump said strike, robot ruled ball: overturned.
  2. 2Iván Herrera — ump said strike, robot ruled ball: overturned.
  3. 3JJ Wetherholt — ump said ball, robot ruled strike: overturned.
  4. 4Jordan Walker — ump said strike, robot ruled strike: upheld.
  5. 5Iván Herrera — ump said ball, robot ruled ball: upheld.

Our tracked-rulebook zone matched the ABS ruling on 2 of 5 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
