What this shows — how Jonathan Parra called the 161 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 150 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 · 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. 1Joe Mack — ump said strike, robot ruled ball: overturned.
  2. 2Joe Mack — ump said ball, robot ruled ball: upheld.
  3. 3Mike Trout — ump said ball, robot ruled strike: overturned.
  4. 4Vaughn Grissom — ump said strike, robot ruled strike: upheld.
  5. 5Jakob Marsee — ump said strike, robot ruled strike: upheld.
  6. 6Tyler Heineman — ump said strike, robot ruled strike: upheld.

Our tracked-rulebook zone matched the ABS ruling on 3 of 6 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
