What this shows — how Erich Bacchus called the 207 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. 181 were right. Below, only the misses are plotted, alongside every challenged pitch.

The zone, as he called it

Challenge 1: Ernie Clement — the ump called it a strike, the robot ruled ball (OVERTURNED — ump overruled).

* Graded on the ABS ruling. ABS measures its own zone, set by the batter’s height and taken at the middle of the plate, and our tracking puts this pitch on the other side of the line.

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

6 pitches went to the robots · 5 overturned (ump overruled) · 1 upheld (ump confirmed). This is the ABS system’s own measurement — Hawk-Eye optical ball-tracking, not our model.

  1. 1Ernie Clement — ump said strike, robot ruled ball: overturned.
  2. 2Brandon Valenzuela — ump said strike, robot ruled ball: overturned.
  3. 3Josh Smith — ump said strike, robot ruled ball: overturned.
  4. 4Brandon Valenzuela — ump said ball, robot ruled ball: upheld.
  5. 5Brandon Valenzuela — ump said ball, robot ruled strike: overturned.
  6. 6Brandon Valenzuela — ump said ball, robot ruled strike: overturned.

Our tracked-rulebook zone matched the ABS ruling on 5 of 6 — a zone-definition gap (ABS grades a standardized, height-based zone). Where the two disagree, the umpire is graded on the ABS ruling.
