What this shows — how Tripp Gibson called the 139 pitches that were taken (no swing), graded against the tracked rulebook strike zone, or, on a pitch the ABS (Automated Ball-Strike System) reviewed on a challenge, against its ruling. 133 were right. Below, only the misses are plotted, alongside every challenged pitch.

The zone, as he called it

Challenge 1: Kyle Teel — the ump called it a ball, the robot ruled strike (OVERTURNED — ump overruled).1Challenge 2: Ryan Jeffers — the ump called it a ball, the robot ruled ball (upheld — ump confirmed).2Challenge 3: Tristan Peters — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).3

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 the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Kyle Teel — ump said ball, robot ruled strike: overturned.
  2. 2Ryan Jeffers — ump said ball, robot ruled ball: upheld.
  3. 3Tristan Peters — 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). Where the two disagree, the umpire is graded on the ABS ruling.
