What this shows — how Charlie Ramos called the 127 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 121 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

3 pitches went to the robots · 3 overturned (ump overruled) · 0 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Joe Mack — ump said ball, robot ruled strike: overturned.
  2. 2Salvador Perez — ump said strike, robot ruled ball: overturned.
  3. 3Brian Navarreto — ump said ball, robot ruled strike: overturned.

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