What this shows — how Cory Blaser called the 137 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 127 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

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. 1Freddy Fermin — ump said ball, robot ruled strike: overturned.
  2. 2Iván Herrera — ump said ball, robot ruled strike: overturned.
  3. 3Victor Scott II — ump said strike, robot ruled ball: 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.
