What this shows — how Jeremie Rehak called the 121 pitches that were taken (no swing), graded against the tracked rulebook strike zone. He got 113 right. Below, only his misses are plotted, alongside every pitch the ABS (Automated Ball-Strike System) reviewed on a challenge.

Challenge 1: Jorge Mateo — the ump called it a strike, the robot ruled strike (upheld — ump confirmed).1Challenge 2: Freddy Peralta — the ump called it a ball, the robot ruled ball (upheld — ump confirmed).2Challenge 3: Connor Wong — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled).3

ABS — the Automated Ball-Strike System

3 pitches went to the robots · 1 overturned (ump overruled) · 2 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Jorge Mateo — ump said strike, robot ruled strike: upheld.
  2. 2Freddy Peralta — ump said ball, robot ruled ball: upheld.
  3. 3Connor Wong — 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.
