What this shows — how Jonathan Parra called the 159 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 139 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

Challenge 1: Jake Rogers — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).1Challenge 2: Will Vest — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).2Challenge 3: Jake Rogers — the ump called it a ball, the robot ruled ball (upheld — ump confirmed).3

The calls that moved the game

  1. 1-0.309 · 3-1 ball called strike
    Jackson Holliday vs Kenley Jansen
  2. 2+0.285 · 1-2 strike called ball
    Jeremiah Jackson vs Framber Valdez
  3. 3-0.216 · 3-0 ball called strike
    Taylor Ward vs Framber Valdez

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 · 2 overturned (ump overruled) · 1 upheld (ump confirmed). This is Hawkeye ground truth, no model involved.

  1. 1Jake Rogers — ump said strike, robot ruled ball: overturned.
  2. 2Will Vest — ump said strike, robot ruled ball: overturned.
  3. 3Jake Rogers — ump said ball, robot ruled ball: upheld.

Our tracked-rulebook zone matched the ABS ruling on 2 of 3 — a zone-definition gap (ABS grades a standardized, height-based zone), not our error.
