What this shows — how Manny Gonzalez called the 142 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 129 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

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

  1. 1Wilyer Abreu — ump said strike, robot ruled ball: overturned.
  2. 2Joe Mack — ump said ball, robot ruled strike: overturned.
  3. 3Joe Mack — ump said ball, robot ruled ball: upheld.
  4. 4Kyle Stowers — ump said strike, robot ruled ball: overturned.
  5. 5Anthony Seigler — ump said strike, robot ruled strike: upheld.
  6. 6Caleb Durbin — ump said strike, robot ruled strike: upheld.

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